Red Hat Bugzilla – Bug 236038
brightness changing is the other way
Last modified: 2013-03-05 22:49:58 EST
Unplugging the AC power makes the screen brighter
plugging in the AC power makes the screen less bright
Should be the other way (less brightness is less energy consumed).
Version-Release number of selected component (if applicable):
What's the brightness settings in gnome-power-preferences?
I don't see any. gnome-power-manager-2.18.1-2.fc7

what does "lshal | backlight" print?

lshal -l output
# lshal | backlight
-bash: backlight: command not found
[root@localhost ~]# lshal | grep light
Looks like it's your BIOS setting the brightness (I too have a Dell that can do
this) -> not a g-p-m bug
