Red Hat Bugzilla – Bug 582830
Unable to dim backlight on Samsung NB30 as no BACKLIGHT support
Last modified: 2011-03-22 09:02:54 EDT
Description of problem:
I am not able to dim the backlight of the netbook nb30 from Samsung. Not with the Fn-keys, nor with the gnome-applet.
The command "xbacklight" returns: "No outputs have backlight property"
Version-Release number of selected component (if applicable):
Fedora 13 Beta
Push the Fn-ArrowUp or Fn-ArrowDown-key or use the Gnome-applet
Dim the backlight of the display
What graphics card does the machine have? This is an Xorg problem, not a g-p-m problem.
It is a Pine-Trail Netbook, so it has the same Graphic Card as all other netbooks, using the N450 processor.
The graphic card is called: GMA 3100
