So, many of you want to run a full-size linux on your iconia. Unfortunately due to the fact that acer are a bunch of stupid mofos not releasing kernel source code and do not allow to flash unsigned ROMs we'll have to run it in chroot within android.
First thing to do is to get yourself a rootfs of linux. You can use angstrom, ubuntu.. I'm building debian using multistrap, the config is below. You'd better use pre-built ubuntu/backtrack and skip up to somewhere between steps 4 and 5, unless you have experience with dpkg and apt-get.
Code:
[General]
arch=armel
directory=/home/alexander/builds/multistrap
cleanup=false
retainsources=true
allowrecommends=false
noauth=true
unpack=true
aptsources=Grip
debootstrap=Debian
[Debian]
packages=screen openssh-server alsa-utils wireless-tools wpasupplicant nmap netcat
source=http://ftp.uk.debian.org/debian
keyring=debian-archive-keyring
suite=sid
[Grip]
packages=locales
keyring=emdebian-archive-keyring
source=http://www.emdebian.org/grip
suite=sid
Now we need to get it to iconia somehow. Running it from microsd would be incredibly slow and internal ssd is formatted to vfat. So let's loop mount it.
1. Create the loopback image
Code:
#700 mb
dd if=/dev/zero of=debian.img bs=10M count=70
mkfs.ext2 -f debian.img
2. Mount it as you always do.. on your desktop yet
Code:
mkdir /mnt/debian
mount -o loop -t ext2 debian.img /mnt/debian
3. Copy the desired files.. As a root user, you can cd to the rootfs (generated by multistrap) and
Code:
tar cvp . | tar xvp -C /mnt/debian
4. unmount the image.. (umount /mnt/debian) and copy to the /sdcard. I copy to the /sdcard/linux/debian.img. Also, I use the /sdcard/linux/uroot directory to mount the image on the tablet.
5. now, you need adb or terminal emulator and superuser permissions ('teh rewt')
Now let's make some script, name it android_sh and put it to /bin in /sdcard/linux/uroot. And make it executable (chmod +x /bin/android_sh)
Code:
#!/bin/bash
export PATH=/bin:/sbin:/usr/bin:/usr/sbin
export USER=root
export HOME=/root
export TERM=linux
if [ -z "`pidof Xtightvnc`" ] ; then
vncserver -geometry 1280x740 -depth 8
else
kill -9 `pidof Xtightvnc`
rm /tmp/.X11-unix/X*
rm /tmp/.X*lock
fi
/bin/bash -
Ok. now make another script, in /sdcard/linux
Code:
#!/bin/sh
LOOPBASE=/sdcard/linux
LOOPFILE=debian.img
LOOPTARGET=uroot
cd $LOOPBASE
if [ -z "`grep $LOOPBASE/$LOOPTARGET /proc/mounts`" ]; then
echo "mounting $LOOPFILE"
mount -o loop -t ext2 $LOOPBASE/$LOOPFILE $LOOPBASE/$LOOPTARGET
else
echo "$LOOPFILE already mounted"
fi
for i in dev proc sys
do
echo "processing $i"
if [ -z "`grep $LOOPBASE/$LOOPTARGET/$i /proc/mounts`" ]
then
echo "mounting $i"
mount -o bind /$i $LOOPBASE/$LOOPTARGET/$i
else
echo "$i already mounted"
fi
done
if [ -z "`grep $LOOPBASE/$LOOPTARGET/dev/pts /proc/mounts`" ]
then
mount -t tmpfs none $LOOPBASE/$LOOPTARGET/dev/pts
fi
echo "chroot into $LOOPBASE/$LOOPTARGET"
chroot $LOOPBASE/$LOOPTARGET /bin/android_sh
now, execute it (sh /sdcard/linux/chroot.sh). You should be in root shell now. If you're building debian using multistrap, configure the packages (dpkg-configure -a). Remember I told you to keep out of debian? Dash package is somewhat broken so you may need to lurk through mailing lists to make it install.. And you need to manually add your sid/testing mirrors to the aptitude config.
So what now? Install tightvnc server (in debian/ubuntu, use apt-get update; apt-get install tightvncserver), exit the shell and launch chroot.sh again.
If you're building rootfs yourself, don't forget to install some x desktop environment. I use lxde on debian, it is lightweight and starts automatically with tightvnc
Now, you can use the vnc client on android to connect to your X11. When chrooting, tightvnc wil tell you the number of x session, so use it as the last digit of the port (5901, 5902 etc). I welcome suggestions on how to improve the android_sh to cleanly kill all tightvnc servers and remove temporary files so that the port number is always the same
In the end you may or may not get something similiar to this:

P.S.
I recommend you to install Hacker's Keyboard which will give you the tab key, esc and arrows simultaneously and allow to use cool software like vim and emacs without pain

Cool...But I got stucked at the first step. Where can I get debian.img?
you create a new file named debian.img using dd, then you format it to ext2 using mkfs.. well. you can just take backtrack image from xoom. essentially it's just ubuntu with some software added
I'm just curious why you chose ext2 as opposed to ext4? Given that the filesystem is actually a file on a filesystem, I sort of understand ext2, especially considering you can mount it with the ext4 driver now.
This probably sounds like a stupid question, but for some reason I cannot use bash?
It may be that my paths are not configured properly, but i dont have a bin at the "/" level. I have looked in /system/bin and /system/xbin, but have not found bash there either.
I installed busybox and have been able to perform root tasks, so I am not sure what I missed.
because.. you don't have bash.. you should have it in your chroot. if you need it in android, just install it (like http://forum.xda-developers.com/showthread.php?t=537827)
I installed bash according to the link you posted, but I still don't have a /bin outside of /system. I did change the above scripts to reflect this by saying:
#!/system/bin (but then I get the error 'event not found')
My prompt reads: "sh-3.2#" after reboot, which I understand is bash replacing the stock terminal.
I tried creating the /bin directory in the root, but even with root terminal, it said it was read only. Do I have to remount the root and then create a /bin directory?
When I rooted, I don't remember their being a lengthy discussion about bash installation, or the creation of a /bin directory.
I welcome all suggestions, as I am trying to learn more about the inner workings of the tablet, but still have little experience.
you need bash only in the linux in chroot and therefore do not need to modify scripts.
anyway,
mount -o remount,rw /system
cp bash /system/bin
chmod 755 /system/bin/bash
mount -o remount,ro /system
then you can start bash by typing 'bash' in shell
Hello,
I have tried and I still can't get it run. I am not used to Linux stuffs and scared that I may screwed up my tab. Can you please pack the required files and upload it so that we can follow easier? something like this http://www.secmaniac.com/may-2011/backtrack-5-on-motorola-xoom-in-10-minutes-or-less/ would be great.
Thank you.
PS: I sincerely want to get BackTrack on my tab so that I can run R on this

I ended up installing bash, but I still had problems with chroot and getting the scripts to run, so I decided to reverse what I was doing. In the process of trying to remove the bash shell and replace with the stock sh, I must have messed something up.
I tried a factory reset, and when I loaded back up again, I can't get wifi to connect. My suspicion is that there is at least two separate things wrong:
-My shell is somewhere in permission limbo or non-existant
I try running >adb shell and I get:
"- exec '/system/bin/sh' failed: No such file or directory (2) -"
-The permissions on my wpa_supplicant are probably messed up, hence I can't connect to wifi
Any suggestions?
Well I tried a few more things:
-Tried copying over bash to /system/bin, got an error that it is a read-only file system. Funny, because I need shell (chmod?) in order to repair the shell, those bastards.
-Tried installing apk using adb, got same message about 'sh' missing. I think I will have to reflash a system.img, but I can't seem to find the Wifi-US with a working link.
Any help would be much appreciated.
Hey guys, could you upload and send me the link of a video of this working? Cause I love the idea of it but I'm not sure if its really practical

Backtrack (http://www.backtrack-linux.org)
Backtrack-Linux.org, home of the highest rated and acclaimed Linux security distribution to date. BackTrack is a Linux-based penetration testing arsenal that aids security professionals in the ability to perform assessments in a purely native environment dedicated to hacking. Regardless if you’re making BackTrack you Install BackTrack, boot it from a Live DVD or thumbdrive, the penetration distribution has been customized down to every package, kernel configuration, script and patch solely for the purpose of the penetration tester.
Here is a guide to getting ARM Backtrack Running on the Iconia A500 (tested on Wifi Only Version, running 3.0.1)
After much frustration I have gotten the GUI part of the backtrack 5 arm release working with the Motorola Xoom.
This has only been tested to work on the Iconia A500 . But it should work just fine with any other device that supports linux, and should work especially well on anything with a dual-core processor (G2X, Atrix, etc.)
Pre-requisites:
- Rooted Iconia A500
- Busybox installed (Find on market Busybox installer)
- androidVNC from the Android Market
- Terminal Emulator from the Android Market (which you should already have)
- Backtrack 5 for ARM with Gnome downloaded and setup (check the README file, and follow the instructions.)
Link: Backtrack 5 http://www.backtrack-linux.org/downloads/. This tutorial will assume you put Backtrack 5 in the folder /sdcard/BT5 like the README says.
Code:
Extract the zip file to your internal SDCARD folder (/SDCARD/BT5)
Open Terminal emulator and type
su
cd /sdcard/BT5
gunzip bt5.img.gz (take about 7-10mins)
sh bootbt
Code:
cd /sdcard/BT5
su
sh bootbt
BackTrack will start up in shell. You will get a red line that says "[email protected]:". To verify if you type:
Code:
ls pentest
It should echo back the folders in pentest, stuff like 'backdoors','database',etc.
At this point enter the following commands:
Code:
export USER=root
vncpasswd
When you type in 'vncpasswd' this is to the the password for the tightvncserver. Since I only connect locally I just use 'qwerty' for my password, and then confirm the password. [Edit] Apparently you can skip this step, as the default password for vnc is simply, 'toortoor' (root backwards, twice).
When it asks if you want to create a view only password just type 'n' and hit enter. After you have your password setup for vnc start the server up.
Code:
[COLOR="Red"]startvnc 1280x800[/COLOR]
When this happens you will get a message confirming that "New 'X' Desktop is localhost:1" and a bunch of other random stuff below it (it isn't important unless there are errors listed).
At this point, press the "HOME" button and then open the application "androidVNC".
-In the "Nickname" box, you can name it whatever you like.
-In the "password" entry, use your password (mine is 'qwerty').
-In the "Address" box you can type in localhost (or leave it blank).
****Change the port from 5900 to 5901.
I also recommend setting the color-depth to 24-bit. After that press the "connect" button, and bam! You're rocking Backtrack 5 on your Iconia A500!!
Code:
In order to exit:
- Go back to Terminal
- Type [B]stopvnc[/B]
- Type [B]exit[/B]
you are back to android terminal environment and ur androidvncviewer will get disconnected.

To mount sdcard, external sd and usb storage in backtrack, you have to modify the bootbt script like this (changes in red):
Code:
perm=$(id|cut -b 5)
if [ "$perm" != "0" ];then echo "This Script Needs Root! Type : su";exit;fi

Works perfectly! Thanks for this!
Thanks very much for this guide!
I'm having a strange issue though, hopefully someone can help. When I press the "m" key, rather than type the letter "m", it opens up the mail icon in the tool bar. Every other letter works fine, and I can't seem to find a way to edit this keyboard shortcut.
Anyone else have this issue, or now how to correct this?
thanks a lot - it will work for me without any error or something else
i use the latest update from acer (A500_1.141.01_EMEA_CUS7)
hmm, is there any trick to log off an turn off the system ? when i exit everthing an try to start again i will only see the backtrack wallpaper...
also i got an error in term-emu when i type in "exit".
I added the OP for how to exit.
Thanks for the guide, I have been waiting for something like this!

doble-tap (right click) the mail icon in the tool bar and choose to remove it from panel. It should remove the keyboard shortcut also.

Just one question.
I suppose you use a bluetooth keyboard, because the virtual one doesn't seem to work with Backtrack. But is it possible to use a mouse ? Because my big fingers don't match the tiny icons and menu choices !!!
Thanks again.

Tanks for your help.
When it asks if you want to create a view only password just type 'n' and hit enter. After you have your password setup for vnc start the server up.
Code:

startvnc 1280x800
When this happens you will get a message confirming that "New 'X' Desktop is localhost:1" and a bunch of other random stuff below it (it isn't important unless there are errors listed).

is it possible to use a different resolution? I tried to use 1280x768 (WXGA read on Wikipedia) but it didn't work.
Hi, Alberto
edit:
Now it works fine! thank you!
Sorry for my first post.
I just realize that I had confused the downloaded archive (.7 z, wich contain all stuff) and the compressed image (. gz), so I did not unpack image before running bootbt.
Unfortunately, the extraction of master archive did not work due to the soft used to extract .7z.
As i mentionned before I've checked the whole archive md5sum but did not check the extracted files.
bt5.img.gz was only 12.59 MB, extracted with androzip. (don't use it, at least for .7z!!)
interesting....
is the wifi adapter working in monitor mode???
I'm posting this in a new thread as requested...
There is a simple way to preapare a custom Ubuntu image file compiled for ARMEL with only the packages and functionalities you need.
For this procedure you will need
- a linux machine with working ADB (I tried it on a x64 ubuntu machine)
- a rooted Iconia A500 with busybox installed
- a little knowledge about what you're doing, but just a little.
1. Install Rootstock
on your linux machine, open up the terminal and type
Code:
sudo apt-get install rootstock
If you use at least Ubuntu Karmic, it should automatically pull all the dependencies, otherwise you'll have to manually install Qemu and a newer debootstrap.
2. Create the tarball
you're ready to download the packages and prepare the tarball.
Remember: rootstock doesn't automatically include a kernel, so you'll have to manually include it in the package list
Here's the syntax for a basic run (run "man rootstock" for all the parameters):
Code:
sudo rootstock \
--fqdn [COLOR="Red"]<YOUR_CHOSEN_HOSTNAME>[/COLOR] \
--login [COLOR="Red"]<YOUR_CHOSEN_USERNAME>[/COLOR] \
--password [COLOR="Red"]<YOUR_CHOSEN_PASSWORD>[/COLOR] \
--imagesize [COLOR="Red"]<IMAGE_SIZE_IN_GB>[/COLOR]G \
--seed [COLOR="Red"]<LIST_OF_PACKAGES_SEPARATED_BY_COMMAS>[/COLOR]
Here's an example for a 2GB image with OMAP kernel and a complete Kubuntu-desktop distribution:
Code:
sudo rootstock \
--fqdn ubuntu \
--login ubuntu \
--password ubuntu \
--imagesize 2G \
--seed linux-image-omap,kubuntu-desktop
In --seed you can specify whatever package you want. You could start with just the kernel and build-essential, then add whatever you need. A good start could be like this:
Code:
--seed linux-image-omap,build-essential,lxde,tightvncserver,openssh-server
This will give you a running ubuntu with a very light, performance-oriented desktop environment (lxde) with ssh and vnc.
Remember: It's still possible to add new packages with apt-get from chroot whenever you want.
Once you have chosen the packages you want, you just have to press enter and rootstock will automatic download the packages and prepare the tarball.
You'll end up with a file named "armel-rootfs-<TIMESTAMP>.tgz"
3. Prepare the img file
This is very easy and quick:
Code:
dd if=/dev/zero of=arm_ubuntu.img bs=1MB count=0 seek=[COLOR="Red"]<SIZE_IN_MB>[/COLOR]
The seek parameter defines the size in MB of your image. make it as large as you want, it should at least be as big as the size you selected for the tarball (2G in my example).
Remember: 1 GB = 1024 MB
Now we format the image. Since the Iconia supports ext4 file system, we can use it!
Code:
mkfs.ext4 -F arm_ubuntu.img
You may want to pass other flags to define advanced options, labels and reserved blocks, but this is the least you need to make it work.
4. Decompress
Now we have to mount the img file in a loop:
Code:
sudo mount -o loop arm_ubuntu.img /mnt
and decompress the tarball into it.
Code:
sudo tar -C /mnt -zxf armel-rootfs-<TIMESTAMP>.tgz
It's done!
[OPTIONAL]
This is the right time to put custom scripts in /mnt/usr/bin like this one to start the vnc server with the correct geometry for the A500:
Code:
#!/bin/bash
rm -fr /tmp/.X1*
vncserver -geometry 1280x752
NB: the A500 screen is 1280x800, but the honeycomb statusbar (1280x48px) is always on top. To avoid panning to show the ubuntu menu bar, we just subtract those 48 pixels from the ubuntu vertical resolution.
Now we just umount it.
Code:
sudo umount /mnt
5. Load on the tablet and get it running
The script to mount and boot is derived from the one in the Backtrack 5 Thread.
Load the img file on the tablet with
Code:
adb push arm_ubuntu.img /sdcard/ubuntu/arm_ubuntu.img
It will take a loooong time and there's no progress bar, so just have faith.
Next, we prepare the boot script. The only thing you need to do is to put your username in (the one you chose in rootstock).
Code:
perm=$(id|cut -b 5)
if [ "$perm" != "0" ];then echo "This Script Needs Root! Type : su";exit;fi
mount -o remount,rw /dev/block/mmcblk0p5 /system
export kit=/sdcard/ubuntu
export bin=/system/bin
export mnt=/data/local/mnt
mkdir -p $mnt
export PATH=$bin:/usr/bin:/usr/local/bin:/usr/sbin:/bin:/usr/local/sbin:/usr/games:$PATH
export TERM=linux
export USER=[B][COLOR="Red"]<THE_USERNAME_YOU_CHOSE_BEFORE>[/COLOR][/B]
export HOME=/home/$USER
export stor=$mnt/home/$USER/storage
export sdcard=$stor/sdcard
export extsd=$stor/external_sd
export usb=$stor/USB_storage
if [ -b /dev/loop2 ]; then
echo "Loop device exists"
else
busybox mknod /dev/loop2 b 7 0
fi
mount -o loop,rw,noatime -t ext4 $kit/arm_ubuntu.img $mnt
echo "mounting storage devices in $stor..."
mkdir -p $sdcard
mkdir -p $extsd
mkdir -p $usb
busybox mount --bind /mnt/sdcard $sdcard
busybox mount --bind /mnt/external_sd $extsd
busybox mount --bind /mnt/usb_storage $usb
mount -t devpts devpts $mnt/dev/pts
mount -t proc proc $mnt/proc
mount -t sysfs sysfs $mnt/sys
busybox sysctl -w net.ipv4.ip_forward=1
echo "nameserver 8.8.8.8" > $mnt/etc/resolv.conf
echo "127.0.0.1 localhost ubuntu" > $mnt/etc/hosts
busybox chroot $mnt /bin/bash
echo "Shutting down Ubuntu ARM for Iconia A500"
umount $sdcard
umount $extsd
umount $usb
umount $mnt/dev/pts
umount $mnt/proc
umount $mnt/sys
umount $mnt
Once done, we can save the file as startubuntu and adb push it to the tab. (the same folder as the img is fine)
Done! We run it by invoking the startubuntu script from the android terminal emulator (must be in superuser mode)
I hope you found this how-to useful.
And we use this distro via our tablets ssh client?

Same happened to me. Totally not fatal. the tarball is good.
For everyone out there:
I would like your help with testing. I have a crash on start problem with firefox in all the images I tried. Does any of you have the same issue?
Hi,
i get
Code:
Loop device exists
then i did
Code:
echo "$kit/arm_ubuntu.img"
and i get
Code:
/sdcard/ubuntu/arm_ubuntu.img
but then i get
Code:
mount: cannot setup loop device: No such file or directory
any ideas?
Because of firefox.
i read a while ago a tweet about a bug in meego and ubuntu in firefox for arm.
when it is this bug then you should try firefox trunk because it is fixed.
but i cannot refind it :-(

i have the same problem. You should make loop file not in /mnt/sdcard, but in /mnt/external_sd.

That would apply only if you put the image file in the external MicroSD, if you have put it in the internal memory (as described in the tutorial) the path is /mnt/sdcard. Also, the speed of the internal memory is better.
Hi,
i found out how i can make it work
but it's strange.
i don't works when i do
Code:
sh ./startubuntu
but with this it works fine:
Code:
/system/bin/sh ./startubuntu
Is this maybe because i didn't use adb.
Someone told me that copy paste might change the permissions (what the ****! really?)
on my tablet startubuntu is not executable.
And it doesn't change anything when i do chmod 755 startubuntu
but after moving it to /system/bin chmod works fine.
After then i can always just run
Code:
su
startubuntu
and ubuntu is up and running.
(many thanks by the way :-D)
Sorry guys, will this method produce a native Ubuntu install similair to how Wubi works? Or is this like the chroot methods were we have to VNC into the distro from within Android?
It is native!!!
but you need vnc to access the xserver
On my n900 i used xephyr but i don't think this is working for android because afaik they don't use X. (n900 is so cool for linux geeks ;-D)
edit:
if you mean with 'native' that it will replace android -> no -> it is a chroot
Yeah that answered my question. Thank you
I'm not going to bother until there is a native distro running with full system resources. I guess with the current bootloader situation that day may never come :-(

It is a chroot/vnc method, currently the only method available to run linux on this device, because of the locked bootloader... I seriously hope for a chance to dual boot in the future.
i was wondering what packages are needed in order to create an ubuntu netbook Edition? Is the A500 powerful enough for that kind of interface?
Thought you guys might be interested in this post.

You realize what a pain that tutorial is to follow? Could you please provide a pre built image at least if asking for scripts is probably way too much?
Hi, this is a guide to install a Linux image on your rooted Android phone with the debootstrap + chroot method.
In this guide, we'll install a Debian image, but the steps are practically the same, with a few tweaks.
If you need help to install a Linux image, feel free to ask on this thread.

VNC
________________
I. On your PC
So first, you have to create the .img file that will contain the OS.
In a GNU/Linux environment (PC) and with the root permissions, type these commands:
Code:
# mkdir debian
# dd if=/dev/zero of=wheezy-armhf.img bs=1M count=0 seek=2048
[COLOR="Red"](NOTE: "of=" will be the name of our .img file and "seek=" the size of the file (MB). Here, we create a file named "wheezy-armhf.img" of 2 GB)[/COLOR]
# mkfs.ext4 -F wheezy-armhf.img
# mount -o loop wheezy-armhf.img /debian
Then we have to fill up the filesystem.
Code:
# debootstrap --foreign --arch=armhf wheezy debian/
# umount debian
Finally, move it to your SD Card. In my case, I moved it on /data/local/
II. On your phone
On your phone, in a terminal emulator and with the root permissions, type the following commands:
Code:
# mount -o rw,remount rootfs /
# export LINUXROOT=/linux
(NOTE: here we'll install Debian on the root of the internal memory, in "/", but we can also install Debian on the SD Card or in /data/loca/linux by changing the path after "LINUXROOT=")
# mkdir $LINUXROOT
# busybox mknod /dev/block/loop100 b 7 100
# losetup /dev/block/loop100 /sdcard/wheezy-armhf.img
# mount -t ext4 /dev/block/loop100 $LINUXROOT
# chroot $LINUXROOT /bin/sh
# export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
# /debootstrap/debootstrap --second-stage
The debootstrap's second part should start. Grab a cup of coffee while it's working!
When it's finish, leave the chroot by typing
Code:
# exit
# su
Let's mount the filesystem. We're close!
Code:
# mount -t proc none /proc
# mount -t sysfs none /sys
# mount -o bind /dev /dev
# mount -t devpts none /dev/pts
Now, we have to set the environment variable. Ensure that you have set the correct path of LINUXROOT in case you've chosen another path than /linux.
Code:
# export LINUXROOT=/linux
# export TMPDIR=/tmp
# export USER=root
# export HOME=/root
# export SHELL=/bin/bash
# export TERM=linux
# export LC_ALL=C
# export LANGUAGE=C
# export LANG=C
And finally, chroot.
Code:
# chroot $LINUXROOT /bin/bash
su
Welcome on Debian!
III. DNS and Mirrors
Set a DNS. We'll set the free Google DNS but you can set yours if you want.
Code:
echo -e "domain local\nsearch local\n" >> /etc/resolv.conf
echo -e "# DNS Google\nnameserver 8.8.8.8\nnameserver 8.8.4.4\n" >> /etc/resolv.conf
You can add mirrors to your sources.list if you want. I'm french so I added french mirrors:
Code:
# echo -e "## Debian Wheezy sources.list\n\n" > /etc/apt/sources.list
# echo -e "## Debian.org FR mirror\ndeb http://ftp.fr.debian.org/debian/ wheezy main contrib non-free\ndeb-src http://ftp.fr.debian.org/debian/ wheezy main contrib non-free\n\n" >> /etc/apt/sources.list
# echo -e "## Debian security updates\ndeb http://security.debian.org/ wheezy/updates main contrib non-free\ndeb-src http://security.debian.org/ wheezy/updates main contrib non-free\n >> /etc/apt/sources.list
IV. VNC
To access your Debian in a graphical environment from your PC or your phone, you have to set up a VNC Server and install a Desktop Environment. Let's install VNC and LXDE.
We'll follow the steps described on the LXDE wiki:
Code:
su
# apt-get update
# apt-get install lxde
# apt-get install tightvncserver
Set up the VNC server by typing the following command, which will ask you to set two passwords (let the second password if you want):
Code:
# vncserver
Kill the session:
Code:
# vncserver -kill :1
Go to /root/.vnc/ and edit the xstartup file: comment out #/etc/X11/xsession and add these two lines:
icewm
lxsession
Click to expand...
Click to collapse
To start a VNC session, type "vncserver -geometry x". For the Nexus 4, we would type "vncserver -geometry 1184x768"
To access your Desktop Environment from your phone, download android-vnc-viewer and launch it.
In the password field, type your password. In the address field, type "127.0.0.1", in port type "5901" and select 24-bit color (4bpp).
V. Script
I've made three scripts to mount, launch and unmount Debian. Whenever you reboot your phone, you'll have to mount Debian, set the environment variables and chroot.

Sorry for my bad english, I hope this will help
EDIT: Feel free to correct me!
Hi, I have 2021 updates, if someone interested. Tested with rooted LineageOS 17 (selinux permissive - not sure if required, my ROM is permissive, didn't set it explicitly):
for 32-bit ARM, ext4 created by 64-bit Linux didn't work, obviously there is some 64-bit feature that was not supported at least with my kernel (3.14). I've in the end created the FS on the Android, but using "-O '^64bit'" could be sufficient in the Linux. UPDATE: I've in the end used F2FS instead of EXT4.
above mknod+losetup+mount didn't work for me (neither 'mount -o loop -t ext4 <img>'), I've used 'mount -t ext4 $(losetup -sf /sdcard/stable-armhf.img) $LINUXROOT' in the end (obviously the device name needs to be saved somewhere if one wants to cleanly umount)
there was issue with network access denied even if you are root, see here. I've fixed it by creating the group 'inet/3003' in the chroot and issuing 'newgrp inet' inside it (more details in the link).
Anyways, thanks a lot for the above instructions, it helped me much!
If we can install full Linux OS on note 10.1 2014, then it will become the truly laptop replacement.
It seems that Linux deploy is very promising, but it require a truly working root
Someone used Linux deploy to install full Linux OS on note 10.1 2012 and turned note into a full Linux laptop when needed.
https://play.google.com/store/apps/details?id=ru.meefik.linuxdeploy
Can someone savvy give it a try?
I've played around with a few installers and in the terminal by hand for a few hours. I am not able to grant permission to chroot. Even with root. I will look into this in the future.

Got Linux deploy (linuxonandroid) app working with work
Hello, Sorry meant to say Complete Linux Installer in the topic, not Linux Deploy!
I tried the Linux Deploy project with no luck. The post that was in this thread got me to the point that you need to apply a patch in the source code ShellEnv.java and then recompile. It sets it up so it prefaces all commands in the script with su when run. I was not able to recompile the code nor anyone that could give it to me. So I moved on to the Complete Linux Installer linuxonandroid app http://linuxonandroid.org/ I ran into the same problems but I was able to get around it because the script that is used to starts the Linux distribution is editable it is bootscript.sh placed in /data/data/com/zpwebsites.linuxonandroid/files this script is automatically created when you walk through the setup/install process while you are downloading an image file going through the setup process you can edit this file as it will be created at that point, where ever you see "$bbox and a xxxxx" in the script you change it to "su $bbox and xxxxxxx" so basically you have to preface all these points which there are a lot of with su. This is part of the situation. Second part is that you will need to setup the mount point for the loop directory by hand and you can see this in the script, then you will need to mount the loop directory and then create each directory inside to what is specified in the script.Then unmount the loop directory, or reboot and then you can finish the setup and launch the distribution.
You may run into errors along the way and you will need to correct them as needed. This is no easy task to setup unless you are familiar with linux and what the script is doing. Sorry I have no easy way but I was able to get it running with the Ubuntu small images to even include the display, still having so issues getting the xwindow to display correctly in the other large images which are close to a full distribution.
All my work was done with a terminal emulator, root explorer, a text editor, Complete Linux Installer(linuxonandroid from ZPWebSites), and a VNC client. Oh and using the spen and Bluetooth keyboard helps as it takes more time with just the touch interface and keyboard for what needs to be done.
It is possible to get running but you have to work at it, took me 3 hours to work through all the issues and I am familiar with Linux and its tools.
Hope this gets you in the direction you need because it was important to me to get this working for what I do. I have sent updates to the developer to hope he can automate this in the future. With Samsung's Android implementation with multiple user config it messes with the security context of scripts because each command can be run through an interactive terminal session. But the script needs to pass SU with the commands to get it to work.
I have a Samsung Galaxy Note 10.1 2014 WIFI P600 and should work with the other models too because not specific to a model. Seems this work with a Galaxy S4 as well since they are setup the same in the OS from what I have found.

Can you upload the edited script?

Yes, I will try. One thing is that the script is producing errors when you try to Exit the running distro with syntax errors on a couple of commands and I have not been able to fix them, they looks like script issues from the generated script, still need investigation and I have contacted the developer. Only way I have been able to get the system to unmount the loop device after an exit is to restart the tablet because of the script errors. Also you will need to create all the file system in the loop directory as the script is not doing it automatically.

Tried to attach file so keep getting error so pasting the script here. Just so you know this is an auto created script on setup so not sure if it is different for each install.

for those brave enough ,try SELinux Permissive Kernel,maybe all problems will be solved.

Yes the kernel in the thread you posted allows for Linux function in Complete Linux Installer. After the kernel is installed either use Wanam Xposed and disabling SELinux to set as always Permissive, or using "setenforce 0" in terminal(this is only for the session and once the system reboots will go back to Enforcing or if "setenforce 1")
At that point if you use getenforce at a terminal will show as Permissive and Linux will boot normally with full function.
My hat goes off to the developer of the kernel because now I have everything on the tablet I need.
FYI on my Ubuntu large installs I am running into a new SELinux issue, even with it in Permissive doing an apt-get upgrade, causes issues with an error related to invalid security context selinux, cant remember the full error. I am not seeing this with the Fedora large image. When this happens with the Ubuntu ones it breaks the KDE GUI and the Application menu ends up blank. The error occurs when install packages try to address the Ubuntu Group security, packages like colord is just an example which do a security group change. Still plowing through how to fix. Till then using Fedora which I haven't used in years
Hi,
I tried with the large Ubuntu image and get an error as well with apt-get update...not being too conversant on Linux on Android, I would like to find out if you had a fix or a resolution from the developers? Might have to stay with the Xperia Z Tablet for Linux in the meantime...
Fedora 19 via Complete Linux Installer. Have Selinux Permissive Kernel, Selinux Mode Changer, and root of course. Otherwise FW is stock MJ6.
Just a few remarks:
The Fedora image is a bit small for a full blown Linux desktop. I copied the contents to a larger 8 GB image. Had to reformat the SD card with exFAT in order to store the image there. Copying was done on a desktop computer because MTP connection just stops at 4 GB.
Changes to scripts include changing the mount command for external_sd to /storage/extSdCard in boot script. Once Linux is up and running, change /root/init.sh, find the line that starts vncserver and append -dpi 300, otherwise fonts in Linux are barely readable. Wigdets are still kind of small but at least the fonts are readable now.
If you get a connection refused in AndroidVNC, you may have to set a password on the Linux terminal for user, that is su - fedora, then vncpasswd.
Todo: find out why second start of Linux fails on loop mount busy and why shutdown complains about umount of dev.
So, my note happily runs KDE desktop, LibreOffice, and kile for LaTeX. The latter was the main reason for putting Linux on the note.

Thanks for the post. I played around with linux on my note 2 and have been waiting to get it running on my 2014. How well does it handle linux?

It runs reasonably well. I guess the limiting factor is disk I/O, or SD I/O in this case. I run KDE 4 in desktop mode with graphical desktop effects disabled and most of the KDE services like indexing disabled. It takes about 15-20 seconds from finished boot to desktop. Once the desktop is up and running, opening apps like LibreOffice is fast enough. Feels like with the first generation Atom netbooks. KDE is a resource hog, it would probably make sense to go for something that is lighter on resources but I chose KDE for girlfriend compatibility. She only knows KDE and I won't force her to learn the XFCE way or something even more obscure like Gnome3 http://forum.xda-developers.com/images/smilies/tongue.gif .
Vncserver runs at native full screen, ie 2560x1600 at 300 dpi. There was a noticable screen redraw lag when closing windows. That was easily fixed by disabling the desktop background image. I have not yet done any high load tasks. Only opened LibreOffice and kile for a quick check.
I have a cheapo foldable bluetooth keyboard. Need to get a small bluetooth mouse. Any recommendations? Or a small keyboard/touchpad combo I can take with me when traveling.

Hum, a step by step guide would be rather longish. To answer the question: Complete Linux Installer scripts are located in /data/data/com.zpwebsites.linuxonandroid/files. There is the bootscript.sh. However, editing it is not strictly necessary. It should work as is. Alright, let's see
Preliminaries:
* need root on your device along with the usual suspects like busybox and terminal emulator (both on Google Play)
* need selinux set to permissive -> flash selinux permissive kernel (to be found in xda forums) and install something like SELinuxModeChanger (Play) set to always change SELinux mode to permissive, check by rebooting and then Configuration > General > Device Info, it should say Permissive
* useful apps include a decent file manager (I like TotalCommander), ZIP extractor (ZArchiver), text editor (Jota), these make things somewhat easier
* required app: AndroidVNC (Play)
1. Install Complete Linux Installer from Play
* start the app and open the menu by touching the < sign at the top left
* choose installation guides (or the like, my interface is not English)
* choose Fedora 19, there are four tabs, work through them in sequence, second tab presents a download button, if you have not yet installed Terminal and AndroidVNC you can use the two other buttons to do it now
* third tab asks you to unzip the downloaded image, the ZIP will probably be in /storage/emulated/0/download, move it to the root of your external SD card, unzip with Zarchiver
* there should now be a new folder fedoraXXXXX with two files in it, the fedora-*.img and an md5 file, you can safely delete the md5 file and maybe rename the image to something like fedora.img, likewise for the enclosing folder
* read the rest of tab 3 and 4
2. Start Linux
* go back to CompLinInstaller menu and push the second entry labeled Start
* a page will open and probably say Ubuntu in the drop down combo box above the Start button, change it to Fedora and type in the path to the image, like /storage/extSdCard/fedora/fedora.img
* push the Start button
* a terminal will open and a few lines will fly by. If everything goes well, you will be asked to set passwords two times, just use a trivial one like 12345678, you can change it later if you are paranoid about passwords
* you will be asked to set the resolution for VNC, type 2560x1600 which is the native resolution of the tab
* you will be asked whether you want to autostart VNC, type y
* you will be asked whether you want to start SSH server, type n
* your choice will be saved right beside the image file, in my case the file is called fedora.img.config, you can change it with any text editor
3. In the chroot terminal
* still in the terminal, the prompt should now say [email protected]
* while you are there, type su - fedora , the prompt should change to [email protected]
* type vncpasswd to set a password for VNC access, just use the same password as above, then type exit
* you are back at [email protected] If you have a keyboard (bluetooth or USB), you can edit the file init.sh with vi and append -dpi 300 to vncserver startup line. This setting will take effect at next start because vncserver. If you do not have a keyboard or do not know vi editor, you can skip this for now.
4. VNC
* start AndroidVNC, Nick: fedora, Password: 12345678, Address: localhost, Port: 5900, Color Format: 24-bit color (4bpp), Connect
* you should now see a linux desktop with tiny fonts
* hit the tabs config button to bring up AndroidVNC options, change input mode to touchpad
* you can now move the linux pointer with your finger on the display
5. Shutdown
* in VNC Linux logout just as you would log out of any other Linux desktop
* terminate VNC session by choosing Disconnect from AndroidVNC config menu
* switch to the still running terminal and type exit
* Linux now stops, wait a few seconds and close the terminal
There are still some minor problems with shutdown which I am trying to trace. A subsequent start of Linux will not work because of busy devices. So best reboot the tab and try again.
That's it for the base setup. Uh, the text is long indeed. Has it worked for you so far? Next comes customization
Corrections welcome, I typed this down from memory...
script
So we need to create script ourselves, when i've done it, i was set resolution to my tablet's resolution, then all is poor to see, that words and windows is too small to work, so it's horrible at the moment, but else works good enough. Is anyone know how to get normal UI on that big resolution? Sorry for my bad english.
Hey guys is there a walk through on how to increase the IMG size for fedora in a windowc pc ? i al ready have the SD partitioned just need to encrease the size to 10 GB
sits at boot up
My device is rooted, chroot installed, vnc installed, and busybox installed.
I install SELinux Permissive and systems sits at bootup screen. never boots to OS at any point. Just sits and the Samsung screen.
I have the Galaxy Note 10.1 SM-P600 (2014 Edition).
How long does it sit at the Samsung Boot screen before finally booting the rest of the way?
I installed using Odin 3.09.
I have running Ubuntu (xfce) on my Note 3 with Linux Deploy. VNC is not the way, it is slow. You should use framebuffer mode and you will be astonished how nice its running. Also, I modified xorg.conf for the phone to only react to stylus input and the stylus button to be right click. This setup is also working on my Note 10.1 old edition.

Can we use it without linux deploy, because it doesn't work on sm-p605? Can you point us to some guide or documentation? Thanks.
