[Bug 725927] [NEW] System freezes when trying to switch users

 

Public bug reported:

Binary package hint: xserver-xorg-video-intel

I have an i865, when I try to switch between users, the system appears
to freeze -- if I switch from the session indicator applet, I just get a
black screen, if from the screensaver unlock window, that window stays
visible.

Pressing Alt-SysRq-k usually manages to kill (and restart) the original
X server, allowing me to log in again.

When I put the hard-disk into a different PC (with an i855) switching
users works (but xv is broken -- different issue).
