Do you use desktop effects/compiz, or similar? They are enabled by default in Gutsy, it could be worth disabling them just to test.

Set it to blank for testing purposes, if so. When in this state, does Ctrl+Alt+F1 do anything? Ctrl+Alt+F7? Ctrl+Alt+Backspace? When rebooting from this state, you may be doing this with a hardware reset button or similar. See if the laptop responds to the key sequence in section 4 of this post: http://matthewstechnologyblog.blogspot.com/2007/06/how-to-recover-ubuntulinux-pc.html Hope this helps, if not fix, then diagnose the problem :) Matthew. -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/
