@NoOp bug #573101 is both 96 and 173 related, there is a package with 96 drivers both for lucid (http://packages.ubuntu.com/lucid/nvidia-96) and maverick (http://packages.ubuntu.com/maverick/nvidia-96), and maverick package's changlog indicate that a patch has been added to cure hangups which are the symptoms. I didn't realize though that 96 does not work in Maverick as you indicated (by the way this report regards lucid not maverick) and I didn't test if 96 from maverick works with lucid. Sorry for that.

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 the issue is (at least at normal debugging levels). To clarify the Xorg shutdown step I did it through top using SIGKILL 9, Default SIGTERM 15 would not take it out. I assume that sudo kill -9 pid would work equally well. I have another 10.04 system running the Nvidia 195.36.24 drivers and there are no issues. -- Logout after switch user causes black screen and disables keyboard and mouse https://bugs.launchpad.net/bugs/585685 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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.

[Bug 585685] Re: Logout after switch user causes black screen and disables keyboard and mouse
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 sudo /etc/init.d/kdm restart from ssh will get you back up and running. Removing nvidia proprietary drivers (version 96 in this case with an older 440MX AGP card) eliminates the issue. -- Logout after switch user causes black screen and disables keyboard and mouse https://bugs.launchpad.net/bugs/585685 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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 machine (again) and top is showing xorg at 99.5%. However, in my case, I can't seem to kill Xorg (even using 'sudo su'). Starting stopping gdm makes no difference either.
