Hi all,
I would like to control the screen's brightness and contrast on my i.mx6 quad board (an udoo quad board) under ubuntu linaro
I tried to modify the brightness through /sys/class/backlight/pwm-backlight.0/brightness but is not working.
I tried the same thing on other files to do rotation and it worked.
Did someone succeeded to do change these parameters ?
Thanks in advance.

echo 200 > /sys/class/backlight/pwm-backlight.0/brightness
try the above & post the status .
does the above help ???
Hi,
Thanks for the reply.
I already tried that. No success.
