I'll post my reply, and if Stephen gets similar results, perhaps we can mark this as a duplicate of Bug 67440.
1. Does using ctrl-alt-F1 to switch to VT works Sort of. When I initially kill KDM, I see the Kubuntu splash screen on VT7 from usplash. Hitting C-A-F1 just gives me a blank screen, but the VT does work (I can issue commands like /etc/init.d/kdm restart). I just can't see anything, so I have to type carefully. 2. Do you have any useful information to /var/log/messages or /var/log/syslog? Hmmm, haven't checked. I'll do that after this reply. 3. Does it happen if you log out of the desktop normally and not by stopping gdm? No, it's only when I kill KDM. -- Issuing sudo /etc/init.d/gdm stop causing system to hang https://launchpad.net/bugs/71687 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
