I started using Arch some months ago and I really enjoying it. Coming from a released based distro, it feels really nice been able to choose exactly what you want to run in your system and always have the packages up to date. For a while I have been planning on running ubuntu in my transformer but I just don't feel too comfortable with ubuntu , so decided to run arch in my transformer. I couldn't find a tutorial so I scavenged the net and found bits and peace that I put together to make this tutorial. What I like about arch is that I am in control of my system and I can run exactly what I want, thanks awesomely documented Arch!
This is a tutorial that will show you how to run Arch Linux in a chrooted environment within your Asus Tarsnformer. I will not provide a simple script that if you run it will do everything for you, instead I will teach you how to make your own installation by grabbing all necessary elements.
You will need:
Arch Live image: Go to http://archlinuxarm.org/developers/downloads and grab the omap 3/4 package.
Install environment: It can be your internal storage or a sd/micro card. Here I will show how to use the micro sd card.
Script for starting the chroot: I grabbed mine from http://forum.xda-developers.com/showthread.php?t=1517993&highlight=chroot and did some modifications. Thanks-miska-
Rooted Asus Transformer(Prime?) with Terminal: You need root to mount the file system and loop devices. In theory this should work in the Prime too.
Linux Machine
Step 1:
For installing arch in a (micro)sd card (I prefer micro as I don't need the dock for using it), first you need to format the card and make two partitions. (I used gparted) Make one partition fat and assign a small amount of space(I have a 4gb micro and assigned 128mb to the fat partition), then make the rest ext4. Make sure the fat partition is first and the ext one is second.
Step 2:
Now as root you need to extract the package in the ext partition of your card. REMEMBER to be root, I got stuck thinking there was something wrong with the package I downloaded but it was that I was unpacking as normal user.
Code:
# tar -c /path/to/extpartition -xzf ArchLinuxARM-omap-smp-latest.tar.gz
Now you have a arch environment in your (micro)sd card.
Step 3:
In your asus transformer create a folder called 'arch' in the root of your internal storage.
Code:
#mkdir /sdcard/arch
Or use a file manager.
Now place this script somewhere in your transformer, I usually keep it in /sdcard/Downloads
Code:
#!/bin/sh
# Modify this according to your needs
DEVICE="/dev/block/mmcblk1p2"
LOOP="no"
# Maybe this as well
MNT_PATH="/mnt/sdcard/arch"
# Modify only if you know, what are you doing
BINDS="dev dev/pts proc sys mnt/sdcard"
ANDROID_BINDS=" /system /data "
TMPS="tmp var/tmp var/log var/run"
MY_MOUNTS=""
unset PS1
# Helper functions
die() {
echo " $1"
exit 1
}
safe_mount() {
mkdir -p "$MNT_PATH""$2"
if [ "$3" ]; then
OPTION=" $3 "
else
OPTION=""
fi
if [ -z "`mount | grep " $MNT_PATH$2 "`" ]; then
mount $OPTION "$1" "$MNT_PATH$2" || die "Can't mount $2!!!"
fi
MY_MOUNTS="$MNT_PATH$2 $MY_MOUNTS"
}
# Real work
[ "`whoami || echo root`" = "root" ] || die "You must be root first!"
LOOP_ARG=""
[ "$LOOP" = "no" ] || LOOP_ARG=" -o loop "
safe_mount $DEVICE "" "$LOOP_ARG -t ext4 "
for i in $BINDS; do
safe_mount "/$i" "/$i" " -o bind "
done
if [ -d /Removable ]; then
for i in /Removable/*; do
[ -d "$i" ] && safe_mount $i /mnt$i " -o bind "
done
fi
for i in $ANDROID_BINDS; do
safe_mount $i /mnt/android$i " -o bind "
done
for i in $TMPS; do
safe_mount none /$i " -t tmpfs "
done
mount -o remount,ro "$MNT_PATH"
chroot "$MNT_PATH" /sbin/fsck.ext2 -y "$DEVICE"
mount -o remount,rw "$MNT_PATH"
# Tweak configuration of the chroot during first start
#if [ \! -f "$MNT_PATH"/etc/profile.d/tweak.sh ]; then
#mkdir -p "$MNT_PATH"/home/opensuse
echo 'nameserver 8.8.8.8' > "$MNT_PATH"/etc/resolv.conf
#echo 'net:x:3003:root,opensuse' >> "$MNT_PATH"/etc/group
#echo 'opensuse:x:1000:100::/home/opensuse:/bin/bash' >> "$MNT_PATH"/etc/passwd
#echo 'opensuse:$1$joWqOQdr$YsapocP32UtdiR3PKBXVM1:15395:0:::::' \
# >> "$MNT_PATH"/etc/shadow
#sed -i 's|^root:.*|root:$1$joWqOQdr$YsapocP32UtdiR3PKBXVM1:15395:0:::::|' \
# "$MNT_PATH"/etc/shadow
#echo '#!/bin/sh
#export TERM=linux
#export LANG="en_US.utf-8"
#export EDITOR="busybox vi"
#alias vi="busybox vi"
#precmd() { :; }
#if [ "`whoami`" = root ]; then
# export HOME=/root
# export USER=root
# hostname -F /etc/HOSTNAME
#fi
#if [ -z "$CHROOTED" ]; then
# export CHROOTED=yes
# export HOME="/home/opensuse"
# export USER="opensuse"
# su opensuse
#fi
#' > "$MNT_PATH"/etc/profile.d/tweak.sh
#fi
export PATH="/bin:/sbin:/usr/bin:/usr/sbin:/system/xbin:/system/bin"
# Chroot
chroot "$MNT_PATH" /bin/bash
#chroot "$MNT_PATH" /root/init.sh
# Cleanup
echo "Umount everything"
for i in $MY_MOUNTS; do
umount -l $i
done
Step 4:
Chmod +x the script and run it as root.
Code:
su
#chmod +x scriptname.sh
sh scriptname.sh
The script will mount the ext partition of your (micro)sd card in /sdcard/arch and will chroot into it. It also does other really nice things, such as mounting your android partitions to /mnt so you can access them from within your arch environment. I have disabled some lines that are used to set up a some environment variables, but you should still be able to get a fully functional command-line environment and you can enable them and modify them as you want.
Step 5:
The rest is completely up to you, now you have arch running in your transformer. But what!? You need X?! really???? Ok, so lets create a vnc server so we can remote into it.
Your network connection should work, so the first thing to do is an update
Code:
#pacman -Syu
Now install xorg
Code:
#pacman -S xorg-server xorg-xinit xorg-twm xorg-xclock xterm
Now install a vncserver
Code:
#pacman -S tightvnc
And now this is the tricky part(And I spent a lot of time in this).
I grabbed this script from the UbuntuInstaller post. This is the script they use for setting a resolution at each boot. What I did was to remove the resolution prompt and fix the resolution to 1280x752(fullscreen) and remove some ubuntu stuff. I also added an export for HOME and USER that will allow you to run 'vncserver' as root.
Code:
#!/bin/bash

/etc/rc.d/sshd stop
Place this script in /root/, give it the name 'init.sh' and make sure it is executable(chmod +x). Now in the previous script comment the line:
Code:
chroot "$MNT_PATH" /bin/bash
and uncomment the line
Code:
chroot "$MNT_PATH" /root/init.sh
Step 6:
Now you should be able to start a vncserver with twm as your window manager and a xterm.
You can now go to
https://wiki.archlinux.org/index.php/Desktop_Environment
or
https://wiki.archlinux.org/index.php/Window_Manager
and set up the desktop environment that you like the most.
Remember that you need to set up the graphical environment to start manually and not at boot. In a normal environment you would usually use 'startx' which will read the .xinitrc file and run the programs from there. In our case put everything that needs to go into .xinitrc into ~/.vnc/xstartup. An example of my ~/.vnc/xstartup
Code:
#!/bin/bash
xrdb $HOME/.Xresources
exec startfluxblox
This will start an empty fluxbox window manager.
I know there is a script to make CM nightlies but I can find it, is there anyone who can point me to the right direction I have a ubuntu server 1Gbps line and 16gb ram that's its sitting idle and I wanna use it for something positive so why not help the community so someone please help me.

I would contact somebody on the cm team.
I saw one of the devs were using one but I can't find the thread to contact him.

They use a compiling bot to auto-compile nightly version.
But I can remember the name of it
I know there is a not but there is also a bash script that does it too.

Here is the script I use to do an automatic sync, build & upload to my site.
This is built on my machine then uploaded to my site.
Its not perfect, but it works everytime, assuming you can build without issues now.
What it does,
Repo syncs with -f (forced) & -j32 (16 or 32 concurrent downloads)
Clobbers
Builds with -j16 (my system has 8 cores so can handle the pressure, reduce this as necessary, also I build for the ace, be sure to change this)
Removes the old build from your system (no need to keep them locally if you upload them)
Moves them to a folder of your choice (currently ~/Dropbox/Public)
Renames them (CM7Unofficial-%TIME_%DATE_%MD5Hash) be sure to edit this to add in your build target - line 69
Uploads them to your webserver, via FTP using ncFTP. Be sure you have installed ncFTP and set it up & created the necessary folder on your webserver - line 80
Also you'd need to change,
The repo location - lines 9 & 50
The build target, mine is ace (Desire HD) - line 36
The output location - lines 43, 50, 53, 62 & 80
And you'd need to set up ncFTP.
I have added comments in for my own reference, but they should point you to the right location should you wish to modify it.
Sadly, other than helping you with this script, I cannot help you with setting up your build machine or anything related to build errors. Use search or Google.
Also remember these are not official builds and should not be named as such.

You'd need to sync the ICS repo and have that ready to build. All my script does is sync a working repo, build & upload.
With Android 4.2's multi-user stuff and the dreaded "0" folder, Google broke mounting of CIFS shares for good. (They basically implemented something utterly useless for my needs, and broke something I need on a daily basis.) Cyanogenmod fixed that for mounts outside the /storage hierarchy, but many apps can't go there. And with 4.2.2, Google made using adb on the device very annoying as well, which adds to problems for a workaround for mounting shares in a useful place.
So I looked around for various fixes for that issue and compiled those into one method that works perfectly well for me on a P6810 running the current PAC ROM 20130629. It should probably work for any other CM10.1 or PA3.6x-based ROM as well. A nls_utf8.ko module compiled for the Nexus 10 is included as well, which can be loaded via punchmod (at least in PAC), so you can access shares with Ümläüts in them.
Prerequisites: SManager, SMWidgets, and a working Busybox install (I use Stericson's Busybox Installer).
1.) Extract nls_utf8.ko and punchmod from the attached .zip file and put them in /system/lib/modules. You can put them in some other place as well, but my scripts need to be adjusted then. Next, give the files sufficient permissions:
Code:
chmod 644 /system/lib/modules/nls_utf8.ko
chmod 755 /system/lib/modules/punchmod
2.) Optional: if you want the module to auto-start, create a file called 00punch-nls_utf8 (or whatever you like) with the content below, put it in /etc/init.d and chmod it to 755. To check if nls-utf8 is loaded after a reboot, type lsmod in a terminal window or adb shell - it should display the module name. If punchmod auto-detection fails, read here how to get the right vermagic string for your device: http://forum.xda-developers.com/showthread.php?p=41920265#post41920265
Code:
#!/system/bin/sh
sleep 10
/system/lib/modules/punchmod /system/lib/modules/nls_utf8.ko ""
3.) Here's the script that mounts a CIFS share. Edit the settings on top and either put your correct vermagic string as well, or delete the "$VERMAGIC" part in line 22 and try your luck with auto-detection. I put some sanity checks in the script, but it might not work for all directories in /sdcard (or, /data/media/0, to call it by its 'real' name/location). If you don't want to use the nls-utf8 module, just delete lines 18-23, and iocharset=utf8 in line 67.
Name the script mount-music.sh or something, put the script wherever you like, open SManager and navigate to the script. Run the script with SU permissions. If everything goes well, it will ask you to accept an adb RSA key, and then adb mounts the share. You can also add a desktop widget for quick access to the script with SMWidgets.
Code:
#!/system/bin/sh
# Your settings here
IP="192.168.1.123"
SHARE="Music"
USER="yourusername"

MOUNTPOINT="/data/media/0/cifs"

if [ "$RESULT" = "" ] ; then
echo "FAILED! //$IP/$SHARE could not be mounted."
else
echo "SUCCESS! //$IP/$SHARE has been mounted on $MOUNTPOINT/$SHARE."
fi
echo
echo All done. You may close this script window now.
4.) This is the script to unmount the share. Name it unmount-music.sh or similar, and edit your settings at the beginning of the script. Again, run it in SManager with SU permissions, and add a desktop widget with SMWidgets if you like.
Code:
#!/system/bin/sh
# Your settings here
SHARE="Music"
MOUNTPOINT="/data/media/0/cifs"
# Check if $SHARE directory exists
if [ -d $MOUNTPOINT/$SHARE ] ; then
# Check if $SHARE directory is empty - if not, unmount the share
if [ "$(su root -c busybox ls -A $MOUNTPOINT/$SHARE 2> /dev/null)" == "" ] ; then
echo "$MOUNTPOINT/$SHARE is empty."
else
su root -c busybox umount -l $MOUNTPOINT/$SHARE
fi
fi
# Show some results
RESULT=`mount | grep $MOUNTPOINT/$SHARE`
if [ "$RESULT" = "" ] ; then
echo "SUCCESS! $MOUNTPOINT/$SHARE has been unmounted."
else
echo "FAILED! $MOUNTPOINT/$SHARE could not be unmounted."
fi
echo
echo All done. You may close this script window now.
Hope this helps some of you. It sure stumped me how incredibly convoluted this simple and much needed procedure has become on Android 4.2.2... just because of that multi-account stuff and new restrictions on adb.

You can try loading the UTF8 module without vermagic string as well, it should work on PAC. Or, make sure you have a blank space at the end of the vermagic string, it is required. Maybe read the short tutorial here: http://forum.xda-developers.com/showthread.php?p=41920265#post41920265

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.

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.

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.

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.
Hey guys, I've just decided to get inside of the Android development world. Anyways, I'm mostly a fan of Linux, so I've made my first Linux script, I know it's simple, but I've never interacted with the user before, or picked an output. When I knew that Android made use of Linux in its core, my interest on working inside it grew up faster than ever.
In my script, firstly, you type the filename. For compatibility reasons, it'll everytime save to /sdcard/filename. Then, it will ask you how many times you want the script to log everything, and lately, every how many seconds should it save everything to the file.
The script will save, before every entry at the log, the screen status (if it's on or off), that can help to, for example, if your device has been lagging as a result of a bad screen driver or UI error.
Last thnig: it also works on recovery (maybe it give some error, and if no dumpsys is present on your recovery's ramdisk, it'll save everything as OFF).
Remember to send it anywhere excepting from /storage and any sbudir, it won't work as the Android permissions system blocks script execution on those dirs.
Code:
clear
# Wipe $logfile content in /sdcard (if any existing)
echo "Please type the filename where you want to save the log: "
read -r logfile
echo "" > /sdcard/$logfile
echo "Deleted previous log."
echo "SCREEN | CPU" >> /sdcard/$logfile
#cont=60
cont=1
#SHOWLOG=X
echo "Please type how many times the cycle must repeat: "
read -r maxcont
echo "Please type how many seconds will the interval take: "
read -r maxmin
clear
# Here it counts how many times the logging script has been ran
while [ $cont -lt $((maxcont + 1)) ];
do
# That nested while takes control of how many seconds have passed in the current cycle
while [ "$contmin" -lt "$maxmin" ];
do
contmin=$((contmin + 1))
sleep 1
clear
echo "C: $cont/$maxcont - T: $contmin/$maxmin"
done
# echo "$maxmin seconds passed."
# Logs the fist line of "busybox top" to a var
LOGVAR=$(busybox top -d 1 -n 1 | grep "idle")
# Logs the screen state (on or off) to another var
SCREENSTATE=$(dumpsys input_method | grep mScreenOn | tr -dc '[:alnum:]\n\r' | tr '[:upper:]' '[:lower:]')
# Saves a string that tells what it should expect if the screen is on
SCREENSTATEON="msystemreadytruemscreenontrue"
if [ "$SCREENSTATE" == "$SCREENSTATEON" ]
then
echo "ON: $LOGVAR" >> /sdcard/$logfile
else
echo "OFF: $LOGVAR" >> /sdcard/$logfile
fi
cont=$((cont + 1))
contmin=0
done
echo "Show logged values? [Y/N]"
read -r SHOWLOG
case $SHOWLOG in
[yY] | [yY][Ee][Ss] )
cat /sdcard/$logfile
;;
[nN] | [n|N][O|o] )
echo "Ok, goodbye. You'll see a what you've asked me to log in /sdcard/$logfile";
exit 1
;;
*) echo "You must write Y or N to continue."
;;
esac
exit 0
For example, save it as script.sh (remember to save it using Unix codifcation, if you're running Windows, else, it'll tell you that it's unable to find many binaries, as long as Linux isn't ok with CR+LF and requires LF as newline). Then, send it to the sdcard (over USB or adb push script.sh /sdcard/) , now, run ADB shell. Type the following commands:
Code:
su -c "cp -f /sdcard/script.sh /data/local/;chmod 777 /data/local/script.sh"
Then, if you want to run it:
Code:
su
sh /data/local/script.sh
That's all, I hope you enjoy it and not so many people kills me for explaining and feeling so grateful for that simple script.
