Laptop brightness on Dell XPS not controllable
Status in “gnome-power-manager” package in Ubuntu:
Confirmed
Bug description:
ERROR: Method "GetBrightness" with signature "" on interface
"org.freedesktop.UPower.KbdBacklight" doesn't exist
The brightness of my laptop's screen is not changed at all when using the Fn-Keys.
Ubuntu displays the notification area with the brightness setting displayed, it even shows that the brightness value is changed - but the actual brightness of the screen remains the same at all times!
Laptop: Dell XPS 17, Full-HD 3D display, Nvidea graphics.
