[FIX] Capacitive buttons NOT lighting up on AOKP with Auto-brightness off

---

This is a dirty fix. I have an idea for a better fix but I am unable to implement it.

These are scripts to be run with Script Manager.

led_on script: 
#!/system/bin/sh
print 80 > /sys/class/leds/button-backlight-portrait/brightness
print 80 > /sys/class/leds/button-backlight-landscape/brightness

led_off script: 
#!/system/bin/sh
print 0 > /sys/class/leds/button-backlight-portrait/brightness
print 0 > /sys/class/leds/button-backlight-landscape/brightness

The value can be set from 0 to 255. I chose 80 as it is good enough and also due to a known issue, as explained below.

Obviously enable root browsing in SManager and run this as root. You can also run led_on at boot if needed. This is a fix when not using auto-brightness.

This will cause the capacitive buttons to ALWAYS be on, even when the screen is off. A simple idea is to check the status of the screen and then appropriately modify that file. But this means a service running in the background and is probably wasteful on resources. But if someone can help me out or have ideas, go ahead and do so. But once done, please lemme know as I am trying to learn.

Lemme know of other issues!

Cheers!

I see you have something for lights in portrait. Maybe also write it for landscape as the lights always go out in landscape.

Did that. This fix is a very hackey one! I wish I could make a more clean one later...
