On Fedora 8, I was able to use the brightness applet and the automatic brightness settings with gnome-power-manager. Since updating it to F9-Beta, it no longer seems to see the panel. Attaching output from gnome-power-bugreport which now shows: Laptop panel present: no
Created attachment 299413 [details] output from gnome-power-bugreport.sh
What laptop model and make?
It's a HP/Compaq V5305WM. Hmm. I thought I had put an update in this BZ, but I guess I didn't... I did find a workaround for this. I put: modprobe video ...in /etc/rc.modules and that made the panel show up. I just commented that line out and retested this and the workaround doesn't appear to be needed now. I'll go ahead and close this bug since it looks like this is now fixed in rawhide.
