Re: [Trisquel-users] grub bootloader trick doesn't work

Interesting that you should mention it, there is a folder  
/sys/class/backlight/asus-nb-wmi/ that I didn't notice before.  I tried:
  echo 100 >/sys/class/backlight/asus-nb-wmi/brightness
{nothing}
But what worked for me was:
cat /sys/class/backlight/intel_backlight/brightness
7182
# echo 95 >/sys/class/backlight/intel_backlight/brightness
