screen backlight setting

[Koppányi Tamás <kornenator gmail com>]

hi!

there seems to be a persistent problem with screen backlight setting under gnome3. even if the correct backlight leves are set in power management, the shell ignores these, and alwyas sets the backlight to maximum when on AC power, and minimum when on battery. is there any workaround for this? it's mostly annoying when on battery, because if i don1T touch the laptopt for a few seconds (like reading some article) the system takes the backlight off to minimum, but doesn't bring it back on when i press some buttons.
