About Double Tap to Wake.

Implemented from scratch and hints from show-p1984 and LG G pad kernels (thanks).

 

The basic idea is known: touchscreen remains _always_ powered to handle input events

and wake up the device with a double tap.

User have to double tap on the _center_ of the screen (to limit accidentally wake ups).

Double tap is disabled by default. To enable it run the command bellow as su:

 

echo 1 > /sys/devices/virtual/input/lge_touch/dt_wake_enabled

 

If you run the above command during screen off, the command will remain pending until

the next power on. Then it will be actually executed.

 

Touchwake functionality is still implemented and it should be disabled if double tap to wake

is enabled.

* You may tune gamma through sysfs using the following path:

/sys/devices/virtual/misc/gamma_control/gamma_r

/sys/devices/virtual/misc/gamma_control/gamma_g

/sys/devices/virtual/misc/gamma_control/gamma_b

 

You have to pass 9 values for each file (r, g, b). For example:

echo "64 68 118 1 0 0 48 32 1" > /sys/devices/virtual/misc/gamma_control/gamma_r

 

For your convinience, franciscofranco uses the terminology below for array's positions

"greys, mids, black, XX, contrast, brightness, saturation, white, XX"

So, he leaves positions 4 and 9 with hardcoded values. (You may also leave them untouched)

 

** In order to enable logger until next Semaphore Manager version:

Copy the /lib/modules/logger.ko file to /data/local/

Then give the file permissions (as root):

chmod 640 /data/local/logger.ko

reboot
