Your laptop is using some form of hibernation/suspension -- probably suspend-to-disk -- and when it tries to awaken from that state, it is not reinitializing your video card properly. Fixing suspend-to-disk, or else configuring your laptop to shut down at 5% power rather than suspend, will solve your problem. -dsr- -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
