Me, too!
I'm running an ATI HD 3450, with Xinerama enabled and apparently working
properly.
HOWEVER, any attempt to log off, or to change users by either the user
switcher or
little-green-man menu, result in black screens and hang. Hard reset is the only
way out: ctrl-alt-bksp doesn't fix it. After I file this, I'm going to see if
restarting
gdm from an ssh, started BEFORE the logoff, helps at all.
I'm running Xinerama, and ATI accelerated drivers are marked as "in-use", but
DISABLED,
by the System/Admin/Hardware Drivers page. I'm trying to run GNOME, across the
board,
for all users, but am not sure how to force that.
The drivers were installed by envy-gt a few minutes ago. All Ubuntu-based
updates
are installed, to the best of my knowledge.
The various patches described by Ilya, etc., appear to have already been made
by
Ubuntu system upgrades. The Stefan patch appears to have already been made, too,
but I'm not sure about any GDM patches. I am running GDM...
This is getting on my nerves, because EVERY TIME I dare to hit the system
upgrade
button, X goes off the air for days or more. I just replaced my NVIDIA card
with an ATI
card, in the hope that it would be more house-broken, but instead, it just
looks to
be also-broken.
