I don't think it's a matter of time but of udev not loading the kernel module for some reason. > Also, restarting kdm gives a stream of errors and a corrupt screen > until it is disabled. This could be due to the X driver in UMS mode messing with the hardware state behind the kernel KMS driver's back. I've pushed a change to xf86-video-ati upstream Git which should make it bail instead in this case. In the meantime, please try loading the kernel module manually before starting X, and if that makes things work better, finding out why udev doesn't load it. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Debian, X and DRI developer -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".
