[FIX][UPDATED 5/28/2012]VivoW AOSP Capacitive Buttons Backlight Fix

---

Hey everyone,

With some edits of cm9 source i managed to get softkeys backlight working.

I have only tested it on cm9 but it should work on MIUI and maybe AOKP.

Thanks

Excited to test it out

alright attached fix to the thread. sorry it took so long as i felt that the button-light-doesn't-turn-off-after-screen-turns-off bug is pretty major and i cant release it until thats fixed.
well that took a lot longer than expected but i think its fixed. It might take up to 5+ seconds for the light to switch but if it take longer than that please tell me.

Thanks

After modifying a light script in Aeroevan's cm9 build I managed to get the buttons backlight semi-working (at least more working than before).

It should work on cm9, AOKP, CNA, and maybe MIUI.

Bugs:
- Sometimes there will be a few seconds lag between screen on/off and buttons backlight on/off
- (Fixed, I think. Need more testing) Sometimes the backlight won't turn off after screen is off. If that happens just turn the screen on and off again and that should fix it.

I based my editing on Aeroevan's script so credit goes to him.
This is just an initial fix and I will try to improve this later on.

Great job, still needs some tweaking but its better than having to adjust the brightness all the time

I didn't try the fix yet but I see that you are modifying the /sys/class/leds/button-backlight-landscape/brightness files. I was trying to come up with a script to do this a while back, but didn't know how. Now I see that this is how it is done! So, are scripts in /system/etc/ run continuously by the OS?

probably not all scripts in /system/etc but rotating_lights.sh is ran by the system every few seconds.

ok so with help and suggestions from litetaker i updated the fix which should fix (how ironic ) the backlight staying on after screen is turned off problem. however there is still sometimes the few seconds lag
