Version 1.0
It bugged me that there was no way to switch off the touchkey backlights on the Nexus S, so I looked into it. Starting with the Netarchy kernel I made some modifications exposing two switches in /sys/.../backlightnotification/ to manually turn on/off the button backlights. However on my i9020 the button backlights get activated automatically once you use the touchkeys - I could not check the i9023 since I do not have one. This behaviour seems to be controlled by the touchkey firmware which only is available as a binary, so without some hex editing the binary there seems to be no way to change this. The next best thing would be to disable the touchkey backlights everytime they get activated, however since I am lazy instead I chose a quick and dirty approach of using a cron daemon to simply trigger the off-switch once every minute. This is good enough so the backlight does not bother me while watching movies, etc. and the extra battery drain is practically zero.

**** ALSO OUTDATED !!!! SEE BELOW ****
Version 2.0
Based on the latest BLN version 9, I made some modifications to implement a backlight dimmer which does not need an external program (like cron) to trigger an off-switch.
To activate the dimmer, just echo the dim interval in ms (this is milliseconds; 1000ms = 1s) into /sys/class/misc/backlightnotification/in_kernel_dimmer. If you pass a value of 0, the dimmer will be deactivated.
Here are the modifications to the source code: http://www.pastie.org/2378721
**** UPDATE ****
Version 3.0
Another day, another backlight dimmer version.
The previous implementations had the drawback that the time when the touchkey backlights were switched off was entirely independent of the time the touchkeys were pressed (and thus reactivated) for the last time. Consequently, the time until the backlights were deactivated was essentially random and could vary from practically zero up to the defined interval value.
Some people commented on that and I agree that it would simply look much more elegant if the dimmer would behave more consistently. So I sifted through the source code and found a way to detect the a press of the touchkeys which both works for the i9020 and i9023. This made it possible to link the dimming of the touchkey backlights to a touchkey press and have the backlights switched off with a consistent delay.
Also, this time instead of being lazy and simply hacking the dimmer functionality into BLN, this implementation does not depend on BLN anymore and can be included in the kernel independently of BLN (with CONFIG_BLD=y). This should improve the maintainability in case BLN or this tweak gets updated.
In /sys/class/misc/backlightdimmer, pass 1 or 0 to 'enabled' to enable or disable the dimmer. Pass the delay in ms (this is milliseconds; 1000ms = 1s) to 'delay'. The default state is disabled and a delay of 5000 = 5s.

The 2.3.4 kernels should work for ns4g. If you run into problems I will look into it again.
I also send Netarchy the changes to the kernel I made and asked him if he could integrate it into his kernel, so I do not have to compile my own version each update. If you feel that this tweak is useful, sending him a PM and telling him that you like this tweak might help (but please do not get on his nerves; he has more important stuff to do).
ah alright, cool thanks
Thanks!

I asked Netarchy if he could include the changes in his kernel but have not received an answer yet.
I am using the latest stable CM, so everytime a new stable CM version using a new kernel will be released I will compile a modified version of corresponding Netarchy kernel (with bfs) including these backlight tweaks for my personal use. So, I can upload these and put the links in here.
However, I am not planning on providing modified kernels for all versions of the Netarchy kernel and for all possible variations (cfs - bfs, custom - stock) anymore. I have published the changes I made to the source code and every kernel dev can easily intregrate these into his custom kernel. So if you want this feature available in your favourite kernel, contact the corresponding kernel dev and ask him nicely to integrate these backlight tweaks.
I too would like this option. I love how sleek the Nexus looks as a black slate. Is making just the changed files into a flashable zip possible? That way anyone on any kernel can use this?

I do not see any way one can achieve the same without a custom kernel.
Alright, I wish I knew how to compile a kernel. I would love to see this option implemented in Netarchy's or Mathkids kernel. I have attempted to contact both in regards to this.
anaglich, I will definitely look into it. Sorry for the late response!
ezekeel: since i only looked at the cron .zip last night after nightshift, i didn't see crond and there is none on my phone. Do you have an arm version to slap on there?
Unless it's part of busybox 1.17, then i'm a victim of old ass cm7 busybox it;s 1.16 and does not have crond either.
Alright, there is also such a thing as "too new", exactly 1.17.1 and there is a crond.
now let's see about installing this. patch is long in.
EDIT: Thanks, seems to work just fine. Can't say it ever bothered me, but i don't watch movies on it either.
EDIT2: Thanks again, users like it. Really appreciate you offering this.
You are welcome. I am glad some of you kernel devs have already integrated this tweak into your kernels.
It was fun figuring out how to compile a kernel and how to package it properly, but once I knew it, it was quite repetitive and got old fast. So for me personally, I am glad that now I have a broader choice of kernels available without modifying it myself. Yeah I am lazy.
Now if I can get Netarchy to include it too, I would be settled for future updates.
Hello all.
I just thought that a pure stock kernel with no other addons except double tap to wake is very much required for our Z phone. That way we would have a complete stock experience(Very much similar to the Z tablet) with minimal inconsistencies in the usage of the phone. I think the present stock kernels are having too many features. Is it possible for the devs in the forum to compile a pure stock kernel with just double tap to wake. Thanx in advance.
So you think there are TOO many features? Why not wait for the 4.4 update, that should have it. Or instead of begging for developers to do things for you, do it yourself.
Q&A for [ROM][M7][SEP2014] AICP - 6.0 - KK 4.4.4
Some developers prefer that questions remain separate from their main development thread to help keep things organized. Placing your question within this thread will increase its chances of being answered by a member of the community or by the developer. Thanks for understanding and for helping to keep XDA neat and tidy! :smile:
I've had this flashed for some time on my M7_UL because it functions so beautifully.
I love it so much that I've forgiven it for making my phone crash 50% of the time when trying to answer a phone call, and at other random times about once a day. Not sure if the newest 7.0 release has fixed that or not.
One feature I'd suggest is enable some sort of default CPU O/C controls and maybe smartassv2.
EDIT: Didn't mean for this to end up in Q&A

Even though the rom now supports wake gestures, the Wake Gestures xposed module doesn't seems to recognize it. It says the kernel doesn't support it or it's not enabled.

You need to flash a kernel that supports wake gestures. Elemental x for example.
Wake gestures are not support in th Stock M7 kernel.
Elemental x is for sense based roms. Not for aosp. And if this rom doesn't support wake gestures, whats this?

The problem still remains the same. I used Elemental x as an example (mainly because I don't know which kernels support wake gestures for aosp roms.)
But the fact remain weather a Rom support wake gestures or not is irrelevant if the kernel running it doesn't support wake gestures they won't work. These gestures are an after market feature for the m7. Only the m8 supports Wake gestures officially.

Hi, is it possible to restore the old s2w and s2s behavior? I would love to update to 7.0 but since the new kernel, I can't wake my device when in deepsleep, or it needs 5 or 6 attempts. Can anyone advice me which kernel I need to flash?
What firmware are you guys using with this ROM for the m7_ul? I've got the ATT version and I want to make try to get rid of some freezing issues I've been having.

This only affects certain carriers. The below fix worked for me.
Do this from ADB shell:

Hi guys,
Just flashed latest nightly of lollipop.
Is the kernel included in the zip best for stability and battery time? Or is there an alternative to be recommended?
A few things I noticed :
Performance settings in ROM control leads to an empty screen that allows searching for all control panel items, is that intentional? I expected kernel tweaker?
Can the x pixel battery bar line be added?
Under settings, and screen, I have an advanced settings headline, but nothing below it? http://i.imgur.com/KYJWJP7.png
What is the status of lollipop in terms of mods that are ported? A lot from 4.4.4 is not ported yet, and xposed can't help due to art runtime. I am aware that lollipop is VERY different from kitkat, and I am not nagging about 'when will x and y be here', just a status from HQ about the transition from KK to LP
Does anyone know about customizing the soft keys and enabling logo key? And does the standard kernel support it?
Any way to customize toggles on kitkat?
I got the wrong apn settings from my carrier, but I guess that's their problem (or mine for running an unsupported Android version they probably do not detect correctly)..
Any way to remove carrier text and camera /call shortcuts from lock screen? So far I have found a guy who will mod system ui apk......
All in all lollipop is awesome, and running superb!! :good:
Thanks to all devs for their time and effort :good::good:
Kind Regards

Battery line at the top of the display. On AICP KK edition it can be 1 to 4 px thick.
Toggles and shortcuts, fair enough
Kernel advice / options?
I miss the Xposed framework, and the rom options for customization, but I will be patient, lollipop is very different from kitkat, and the work being put into this by devs is truly amazing!
I have had a few instant reboots, that's all the problems with this rom so far, and that's really very acceptable

Hello, I'd like if somebody could just confirm that. Also, are they trying to achieve it or it is just impossible?
I think some of the roms have some of the moto actions. You will have to read them to find out which ones.

No Moto apps are present in any of the ROMs
But in CM 12 based ROMS You have gestures which have been ported
1. if u wave over your phone the display will pulse kinda like active dsiplay
2. You can silence the call also by waving over the Screen
3. You can Open camera by twisting like stock rom
4. You can open flashlight by chop gesture
And in Render Kernel for CM 12 you can double tap to wake the mobile
So either u can use stock + gravity box or move over to CM12 which has theme engine and other useful features
Personally i came back to Stock from cm12 because of Performance and battery

Dt2w always working. But .... it seems that the tapping is time sensitive. Tapping 'slow' does not work.

If your ROM has it built in, which many do, then it is really buggy and simply setting dt2w in elementalx - it will still use ROM implementation. If you want to use Kernel DT2w, you must also set one of the sweep options too.
I'm on stock Android with ElementalX, I wonder why it only works sometimes. I have that enabled as well as sweep 2 sleep on. The double tap isn't always 100% responsive.

How are you activating dt2w?
If it is with an app may be activating google dt2w and not flar2's gestures. From what I understand, when dt2w is unreliable is if you are using the incomplete google code found in stock android. But flar2 wake gestures are much more reliable. I found double tap and sweep up to be 100% reliable as far as I noticed. I'm using the donate elementalx app to adjust the settings and elementalx kernel with cataclysm rom.

I meant one of the sweep to wake gestures.
if you're not finding elementalX gestures reliable, its a timing issue as someone else suggested.

yeah both options just write the same thing to a text file, so it makes no difference.
The sweep to wake option only improves dt2w if you're using the "stock implementation" that wasn't actually implemented. Only if you've downloaded a stock rooted "custom" rom would you have this.
That said, i found dt2w very dodgy in my pockets when I had no screenlock on so I only use sweep now.
