macbook, keyboard backlight keys not working after suspend

[Jan Rüegg]

-- outdated, see last post -- I suspect since the last big Ubuntu update I can't control the backlight of the keyboard anymore with the Fn + F8/F9/F10 keys. Everything else still works (backlight of the lcd, volume, ...).
After a fresh install of Ubuntu 8.04 this worked, too. But, as I sayed, not anymore, its just nothing happening anymore when I'm pressing these buttons. -- outdated, see last post --

Just found out that this happens only after suspending. Before, everything works fine (backlight, volume, keybourd backlight), but after suspending to ram and waking up again, the keyboard backlight keys won't work anymore and the backlight keys don't show the usual picture when changing the brightness, but the volume keys work as before...

Another note: After hibernating it keeps working, so the problem must be with some modules not unloading and reloading when suspending but only when hibernating and rebooting...

The keysims sent from the keyboard before and after the suspend are the same (looked up with xev), so maybe some gnome service not started anymore?

I have just spotted the problem: After killing and restarting the gnome-power-manager, everithing works again. Is it possible, to do this automatically after the suspend?
