Comment 11 for bug 295251

Hi edufl13

as a workaround you can use:

sudo apt-get install gconf-editor xbacklight

gconf-editor

apps -> metacity global_keybindings

assign
run_command1 <Alt>F11
run_command2 <Alt>F12

or any keys you want.

apps->metacity->keybinding_commands unter

assign
command_1 xbacklight -dec 10
command_2 xbacklight -inc 10

restart xserver ... alt f11 and f12 will set the brightness.

more important for me is the WIFI off problem ....
