Comment 37 for bug 112518

When I switch from one user to another I get the black screen. Logging in remotely I see that what I presume is a new gdm process consumes almost all CPU:

root 5732 99.6 0.5 15312 6160 tty9 RLs+ 15:33 9:40 /usr/bin/X :20 -br -audit 0 -auth /var/lib/gdm/:20.Xauth -nolisten tcp vt9

It is no problem otherwise to work on the box from a ssh session. But when I try to kill the above process with "kill -9" the box hangs completely, including the ssh session. Any other specific information you want from the ssh session while in "hang state"?
