Disabling authors screensaver

Is it possible to completely disable the automatic activation of the screensaver? I don't see it in settings, the longest interval for this to happen is 1 hour, but no option to disable it completely. I already installed the No Lock app, but this only helped me to get rid of the slide to unlock screen. Thank you for any ideas.

All settings are here:
http://developer.android.com/reference/android/provider/Settings.System.html
In you case you'll need:
adb shell
sqlite3 /data/data/com.android.providers.settings/databases/settings.db
-- check current value
select * from system where name='screen_off_timeout';
120000 - 2 min
3600000 - 1 hour
2147483647 = 596.5 hours
-- set
update system set value='2147483647' where name='screen_off_timeout';

or you can pull/mod/push alternatively.

Won't disabling the screensaver keep the screen and IR sensors active, thus eating up battery life significantly when not in use?
I know some folks would like to get rid of the swipe, waking up on a screen tap (mostly for accessibility issues), but I think some sort of screen (actually, battery) saver is still important.
Great link, ApokrifX. Would you happen to know if WIFI_SLEEP_POLICY does anything on the NST? I use Tasker to shut wifi off when the screen goes off, but I wonder if that might be easier?

No idea.
I bet, it won't work...
Try and let us know?

I need to find a program that will let me know when wifi is on or off relative to the screen. On other devices, I can see that info in the battery status, but I'm not finding a similar option for the NST.
I *did* find a little program that would toggle it, but the NST lasts so long on battery, it's hard to tell if it's making any difference.

Actually, to disable the screensaver completely:
Code:
update system set value=-1 where name='screen_off_timeout';
I haven't found a way to disable the keyguard yet, but if you have one of the side keys set as Menu that dismisses the keyguard.

Hi Renate again ( you adviced me with manual time set in NST
http://forum.xda-developers.com/showthread.php?p=30560605#post30560605, thanks).
I like the tweak (to disable the screensaver completely) also. But not understanding how to do this in internal terminal. Not shell and not busybox know the sqlite3 app and update command?

I fixed it so:
you must install SQLite3 to the NST you can just push it to the device. [unzip sqlite3 (push to n2e).zip]
Code:
adb shell mount -o rw,remount -t ext2 /dev/block/mmcblk0p5 /system
adb push sqlite3 /system/bin
download it from here:

This makes a lot of sense... it explains my battery drain when the screen gets stuck on the "drag to unlock your NOOK" page after a reboot. Basically you have to make sure the Nook really goes to sleep.
Disabling the IR sensors and wifi are then the key to long battery life on the NST.

For anyone trying this technique: I used the pull/mod/push approach and Renate's recommendation of a -1 value, and everything seems to be working well, but I had to powercyle (power down, then power up) my Nook to get the change to take effect.

back button LED for notifications, anyone?

FWIW, I FOUGHT WITH THIS FOR A WEEK AND GOT NO WHERE. THE TASKER PROFILE LISTED IN THE REDDIT THREAD BELOW WORKS GREAT ON MY ROOTED PHONE. ALSO, LIGHTFLOW WORKED ON MY ROOTED PHONE. SO I AM JUST GOING TO ASSUME THIS REQUIRES ROOT
So, i have been searching and reading and asking around and I STILL cannot get the power button LED to light up with notifications.
I have lightflow installed
I have the notification and accessability settings turned on for the app
I have back button led 1 and 2 turned on
I have them turned to "always" on for notifications (I dont expect it to pulse)
I have the brightness set at 255 (But i have tried all other numbers in between)
I am NOT rooted
I am on stock 4.4.2
all other LED notifications seem to be working just fine and are the colors/speeds I set them to.
anyone able to get it working? not sure what else I can try to get it working.
if you have it working on stock rooted 4.4.2 let me know what options you have checked and unchecked in the "settings" page.

guess I'm the only one with this problem eh? lol

I didn't think it did light up. Only time mine does is when unlocking the screen.

Haha, on AOSP ROMs I used tasker to run a script that changed the values in the file that controlled the 2 back LEDs to 255 when I got a notification. Then it cleared the file, and so on until I turned the screen on.
I don't remember it exactly, and I'm pretty sure it would need root.

interesting, I poked around for a bit in tasker and didn't see anything in there for the back buttons. if you happen to come across this, or remember it, please let me know.
edit: i found the profile on Reddit to do this. going to give it a try in a little bit

Oh, please link me the reddit profile. It is probably better than mine. Haha.
Edit: Found my profile. I set it to trigger at a notification event. Works for me. (Remove the .txt at the end if you want to load it into tasker and look at it).

here is the reddit thread. looks like it requires Root so I didn't even try it.
http://www.reddit.com/r/lgg2/comments/20769k/how_to_use_tasker_to_control_the_back_button_led/
but thanks for your profile. I loaded it, and it isn't giving me any errors, but I'm still not getting it to work. I have it set to trigger when a notification event happens...I set Hangouts to the "owner application" and still not getting it working.....I have almost given up on this working without root.
thanks for you help though. if you think of anything, I would greatly appreciate any help, but dont bend over backwards for me...haha

[Q] Scheduled Shutdown

Hi,
I recently got fed up with forgetting to power off my nook. So I figured out I could use Tasker to shut it down at night when it is idle, etc., but I while I was testing it I realized that when my Nook is shut down, it shows the last state of the screen before having been shut down. It is quite annoying, especially that I cannot find a workaround, since Tasker cannot unlock the locked screen.
So, my question is, that does somebody know whether there is a shell command to power off the Nook like when you press the power off button?
Or any other suggestions would also be great.

In my experience letting the nook go into standby for 8-12 hours before using it again uses less battery than shutting down completely and rebooting it.

I use Quick Boot v4.2, Plus version which has an additional command useful for phones: Hot Boot. Free version is good enough for NST:
http://play.google.com/store/apps/details?id=com.siriusapplications.quickboot
I use a WiFi shutdown timer on my phone though, as sleep function on shoutcast radio.
P.S. As mentioned before in my apps listings thread for standby & screen blanking I use Screen Off FX:
http://play.google.com/store/apps/details?id=jp.co.kixx.tool.offwidget

Well, maybe I wasn't making myself clear enough. The most important part here is automation. So while screen off fx is awesome, I can't really use it in this situation since my screen is already locked when I want to turn my Nook off.
The thing I am searching for is a command or an app that could shut down my Nook (even when my screen is locked) in a way that it shows the usual "Your Nook has turned off completely" picture. (Every app that I tried has made the Nook show the screen that is has shown before having been shut down.) And I would like to do all of that automated, probably with Tasker.

The way I would do it is unlock the screen, overlay an image of whatever you want to be shown using a scene, and then shutdown.
To unlock the screen, try Simulating the "n" button command with tasker to unlock the screen before shutting down. (assuming slide to unlock is disabled):
Procedure for simulating button:
In your Tasker task, Create a new Run Shell Action. (Found in the "Script" category)
In the command section, put the following:
Code:
sendevent /dev/input/event1 1 102 1
sendevent /dev/input/event1 0 0 0
sendevent /dev/input/event1 1 102 0
sendevent /dev/input/event1 0 0 0
This will send a press and a release event of the n button.
​
Check the Use Root Option.
NOTE: If this is the first time you've used root with tasker, the root confirmation dialog will appear. Make sure to check the always allow option so that it doesn't pop up again.
Just For Reference:
If you would want to use other buttons do the following:
Replace 102 with:
Power Button: 116
Replace event1 with event0 AND 102 with:
Top Left Page Button: 412
Bottom Left Page Button: 139
Top Right Page Button: 407
Bottom Right Page Button: 158
Good Luck!

Absolutely woderful!
This is exactly how I wanted to do it. :victory:
It works perfectly, thank you very much.

Pushing stuff into /dev/input is lower level than it need be.
You'll be working with scan codes there.
In a shell this sends a press of the power button (using a KEYCODE)
Code:
input keyevent 26
Shutdown is easy enough (with one small hitch).
Simply send a android.intent.action.ACTION_REQUEST_SHUTDOWN
The problem is that this is a privileged intent and can only be sent by system apps.
System apps are those that have the system signature.
You can do that by re-signing your system.
You need to have android.permission.SHUTDOWN in the manifest.

You can do that by re-signing your system.

Well, how can I do that?
And does this command you mentioned have the same efect as reboot -p?

Ok, good to know. I just went for the scan codes because I knew how to quickly get them from shell getevents.

If all your looking for is to do a shutdown or reboot, and are already using a Tasker task, the action Misc > Reboot has the ability to shutdown or do a reboot. My guess is that it does exactly what Renate NST is telling you to do - send a shutdown intent - behind the scenes. Granted, I don't know, and I don't have Tasker installed on my nook so I can't confirm that it will actually work, I have just used Tasker on other devices and it seems to work fine.
Just seems like the easiest, cleanest way would be to keep all the actions under one roof.

Hmm, I don't know. A regular root and su won't work.
You'd either have to have a system-signed app or hack the permission system.
There is no clear info on the difference between an Android shutdown and a Linux shutdown.
Given the choice, I'd go for the Android shutdown.

Well I had a stack overflow link that shows a way to do it, but I can't post links yet. Either way, apparently there is a way with only root. The code from the link was:
Code:
try {
Process proc = Runtime.getRuntime()
.exec(new String[]{ "su", "-c", "reboot -p" });
proc.waitFor();
} catch (Exception ex) {
ex.printStackTrace();

How to change power-off timeout on Nook Simple Touch?

Hi, does anyone know how to change the power-off timeout on the Nook Simple touch? When it automatically switches off and leaves a screen saying "Your Nook has been turned off to conserve battery power" or something.
I've looked in /data/data/com.android.providers.settings/databases/settings.db but there is no setting available.

What do you mean by "power-off timeout"? That screen appears only when you have intentionally shut down your device by long pressing the power button and then confirming through the onscreen dialog that you want to power off the device.
Or are you talking about the forced shutdown when the device decides there is not enough battery power to stay on?
The only "timeout" I can think of is the screensaver timeout which is found in Settings.

My Nook will shutdown at 60% battery power, or 40%, or 20% or something, and it will say that. I remember the word in particular is 'conserve'. I think when it's run out of battery it says something different.
Is there another way to have it shutdown after a period of time? I've seen a thread about using Tasker, but you have to purchase that from the Google Play store. I'd prefer to use a script or something.

It should not be shutting down until it's in the 20's, maybe less. Something is not right--but you knew that.
The question is, hardware or software? If it's software and you do a backup, factory reset and restore the backup, you may be right back where you started. If it's hardware, nothing you do will fix it.
A third option is to do a factory restore and rebuild your system, rather than restore a potentially corrupted backup. That way if it's not hardware, you may solve the problem.
As an afterthought, there are some "battery recalibration" apps out there--not sure if any for Eclair, though. I'm a little leery of their promises, but it might be another thing to look into.
Tasker can do many things, but I'm not sure this is one of them. There is only one version that runs on the NST. PM me for more info if you want to go that route.

I think I will make an app that does what I want. Where can I find documentation on Android 2.1 and/or information on building an app for Android 2.1? I can't find any on google, nor and the official documentation seems to only be for the newest Android versions.

You can prepare custom tailored file named "debuglog.sh".
Then put it into /system/bin folder.
NST's android will run it every ~10 seconds.

I will check that running the script doesn't significantly increase battery consumption. If not, then this should be very very helpful in extending the battery life

nook cannot wakup easily from case like this

So after running my script for the night, the battery has gone down by 11%, so running it with a wakelock is not a viable solution.
Ideally I could have the kernel schedule wake-ups, like I was trying before, but I can't seem to do that.
Apparently /dev/alarm is used by Android to schedule wakeups, but everything I find talks about using it from an app, instead of writing to it directly from commandline.

What service/task would You like to keep running against battery saving? Epaper driver may be power hungry, but maybe You can turn off some android services or wifi driver?

The script is what eats up battery, nothing much I can do to improve it, it's running the 'timeout cat ...' command.

I'm a little late to the thread, but I use a simple app called AutoPowerOff to control this. It doesn't seem to have any affect on battery when the system is on.
AutoPowerOff for Android - APK Download
Download AutoPowerOff apk 1.0.2 for Android. Auto power off your device to save battery life.
apkpure.com
In the app itself, you can only set the timeout to a maximum of 23 hours 59 minutes. I wanted a bit of a longer timeout, though, and found that if you edit the app's settings XML file in /data/data, you can set whatever timeout you want. I use 72 hours, which is perfect for my habits. If I go three days without using my Nook, usually it means I'm going to go a few weeks. This way, I still have a nice charged battery when I do come back.

Question Tasker acting weird.

I have a Problem with tasker. Ive set up a profile to blink one of the glyphs endless if a notification arrives untill it is gone. It works but as soon as the screen turns off and the phone isnt moving, the task is very slow. The glyph should blink for 0.25 sec every 2 seconds but instead the glyph-on-time is at least 30 seconds. As soon as i move the phone, its normal speed again. I did disable battery optimization for tasker but that wont help. Also ive gone through this list and found nothing helpful. Anyone a hint for me?

Can I ask how you made Tasker to cooperate with glyphs in the first place?
