Comment 3 for bug 80339

I'm not sure this is the case. I had Gnome freeze on me while logged in as (say) user1 (that freezing is a separate problem, don't know why that happened yet) and I wasn't able to do CTRL-ALT-F(n) for whatever reason. However, if I SSH in and run /etc/init.d/gdm restart I get roughly the same behavior - the same frozen screen is still on the monitor, and if I log in as user2 and then run "sudo killall -u user1," I still can't get restarting gdm to make a difference on the monitor, and I get a new message in /var/log/daemon.log "WARNING: Display :0 is busy. There is another X server running already. " each time I try.

(I'm using a new installation of Ubuntu 8.10, I'm not sure if this is a different bug as the one described here.)
