Description of problem ---------------------- When changing the brightness level on gnome-shell it has no effect on the screen backlight. Gnome by default adjusts the value of "/sys/class/backlight/nv_backlight/brightness" when it should adjust the value of "/sys/class/backlight/intel_backlight/brightness" as the intel card handles the output. The default behaviour is understandable for desktops but it doesn't work for laptops. Additional notes ---------------- * The system is an optimus laptop, it consists of 2 graphic cards where the intel one handles all the output. * Only open source drivers, i915 and nouveau, are used. * PRIME is used to switch cards, not bumblebee. * While changing the brightness on gnome's slider or using the hotkeys the file "/sys/class/backlight/nv_backlight/brightness" changes too. * xbacklight works fine, it changes intel_backlight only.
