I'll commit this to udev as soon as I get write permissions back. > I have managed to get the scan code=A0(0x96 and 0x97) to respond with > the correct key code (kbdillumup and kbdillumdown) when I run > /lib/udev/keymap -i input/event4 >=20 > However the keyboard backlight level still does not change when these > buttons are pressed. I can't test these myself as I don't have an illuminated keyboard, but gnome-settings-daemon's "media-keys" plugin has code to react to these: http://git.gnome.org/browse/gnome-settings-daemon/tree/plugins/media-keys= /gsd-media-keys-manager.c#n1549 Can you please ensure that X.org actually knows about these? Please run "killall gnome-settings-daemon", then "xev", move the pointer into the white window and press Fn+F7/F8. Do you see keyboard events for XF86KbdBrightnessUp/XF86KbdBrightnessDown in the terminal?
