Raspberry pi touchscreens get blanked and then later the backlight turned off.
When in X of some sort, taps on the screen can turn it back on.  When in a console
taps on the touchscreen are not seen and the display stays asleep.

This script polls mouse inputs in /dev/input for any action on the raspberry pi touchscreen
if there is action, update the file which controls the backlight power to
turn the backlight back on.

This should be tweaked more to not be constantly writing to the bl_power file, possibly monitor
