I am having the same problem. But first I get the notorious xsessions login error message. That goes away after a few seconds, then I get the black screen with the x cursor.
The following seems to occur around the time it happens: May 30 21:23:14 server1 gdm[9367]: Gtk-WARNING: Ignoring the separator setting ... [some time out messages regarding nfs mounts] . . . <-- could this be why? Then I think this happens when I hit Ctrl + Alt + Backspace: May 30 21:25:39 server1 gdm[6456]: WARNING: failsafe dialog failed (inhibitions: 0 0) May 30 21:25:39 server1 kernel: [ 264.543047] [fglrx] interrupt source 10000000 successfully disabled! . . .
