I am also having this problem, typically when I wake my computer up from suspend. The system starts up with a password screen for the user who was active when the machine was suspended. That person can log in, but the "switch user" button just causes the system to go back to the screensaver, with the original person logged in. I think that Ctrl-Alt- Backspace will generally restart X, but that also kills all of the other logins.
I have a completely up-to-date Intrepid i386 system. Compiz is enabled. Attaching output of `sudo lspci -vvnn` and the /var/log/Xorg.0.log file Also of interest may be that when I run: $xprop | grep WM_CLASS I get: WM_CLASS(STRING) = "Navigator", "Firefox" Should this be "gnome-session", "Gnome-session" as shown by the original poster? Maybe this is a clue as to what has gone wrong. I am also pretty sure this problem disappears if I fully reboot. Seems to mainly happen after cycling through suspend mode.
