I would like to disable the automatic screen dimming when I plug in our out my power adapter. Every time my laptop switches between battery/ac, my screen dims even though I have disabled it in every place I could think of.
gnome-power-manager does not seem to be involved, as killing it makes no difference. However, here are some of my settings:
In my gconf, under the key
/apps/gnome-power-manager/backlight, I set:
/apps/gnome-power-manager/lowpower, I unticked all options.
Where else can I control screen dimming?
