I'm running:

  • Debian Jessie
  • Gnome3
  • fglrx drivers
  • Asus Laptop : VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Kaveri [Radeon R6 Graphics]

The max screen brightness is too dim.

I have tried manually adjusting it with xrandr and xbacklight but nothing happens. I recently install fglrx drivers to fix the issue of the gnome login screen becoming frozen after hibernating. This issue remains.

echo 100 > /sys/class/backlight/acpi_video0/brightness

The above also does nothing

Followed this guide for installation: How to install AMD Catalyst 15.7 (fglrx 15.20.1046) on Debian 8 (Jessie)?
