Gary, too bad, that looks like another bug in gnome-settings-daemon. We already make sure that we can turn on/off the display through bl_blank in /sys/class/backlight/eeepc-wmi So, everything in kernel are all set. I just check the gnome-settings-daemon code and fount in plugins/media-keys/gsd-media-keys-manager.c +2126
case KEYBOARD_BRIGHTNESS_UP_KEY: case KEYBOARD_BRIGHTNESS_DOWN_KEY: case KEYBOARD_BRIGHTNESS_TOGGLE_KEY: do_keyboard_brightness_action (manager, type); break; And in do_keyboard_brightness_action(), it will call g_dbus_proxy_call (manager->priv->power_keyboard_proxy, type == KEYBOARD_BRIGHTNESS_UP_KEY ? "StepUp" : "StepDown", NULL, G_DBUS_CALL_FLAGS_NONE, -1, NULL, update_keyboard_cb, manager); You can easily find that, the brightness toggle type is gone. So that gnome-settings-daemon will do nothing while receiving the keyevent 431(which is KEY_DISPLAYTOGGLE). I'll file a bug on bugzilla and link back to this bug tomorrow.
