You do realize that bug #573101 is nvidia-173 related and *not*
nvidia-96? Further, there are no '96 drivers in nvidia-graphics-drivers
and nvidia-96 does not (yet) work in Maverick 10.10. This bug report is
filed in the proper package and is nvidia-96 specific.

Bottom line. Does 96 from maverick work in lucid preventing the hangup?
I'll test with 96.43.18-0ubuntu1 today.

@Igor: 96.43.18-0ubuntu1 on lucid 10.04 resolves the issue for me. I can
switch between users, logout between users, and all works.
Remarking this as a duplicate of 573101 -thanks. I'll add my
confirmation
I can confirm that this bug affects also nvidia-driver-173. No problems
with noveau though.

Logout after
I would say that this brings Nvidia 96 driver to the top of the list as
the likely culprit. I do not have to do any user switching at all. Just
a logout from the intitial session (kde or fluxbox), passing control
back to KDM will cause the issue. Xorg.log does not contain any
indication of what
Well, I just went to shut that system down and the bug is back.
Currently running the Nouveau driver. This time there is no high CPU
use. I did not have to kill Xorg but I did sudo /etc/init.d/kdm restart
to get my screen back. So it is some issue with the logout transition. I
can help test more
OK, I removed the Nouveau driver as well and X now starts with the NV
driver. I can freely login/logout and switch between KDE/fluxbox with no
black screen lockups. So this once more appears to be a video driver
issue.

Duplicated on Kubuntu 10.04. Running KDM with either KDE or fluxbox
results in blank screen on logout (exit) from X session. SSH from
another computer reveals that Xorg is at 100% cpu. Kill xorg followed by

Thanks very much for the confirmation PatG. So we can possibly rule out
GDM being the cause 96 as the issue. I just reproduced on a gnome

can't seem to kill Xorg (even using 'sudo su'). Starting stopping gdm

Sorry should be ' confirm 96 as the issue.'

Hi NoOp, thanx for your hint (https://bugs.launchpad.net/ubuntu/+source
/xorg-server/+bug/546578/comments/96).
It's the same for me. I switched to the vesa driver and the issue was
gone. Then I switched back to the nvidia driver and the issue is back
again. Look at
I'm not sure if this is an nvidia bug. I'm using an ATI Raedon and have
the same problem. Standard-installation standard gfx-driver.
