First X session crashes after secondary local X logon

[Milan Knizek]

Binary package hint: xorg

Hi!

I am using Ubuntu Hardy Heron x86_64, with current updates;
nvidia-glx-new 169.12+2.6.24.14-21;
xorg 1:7.3+10ubuntu10.2

When I login as another user on the second graphical console (CTRL+ALT+F9), the first X session crashes after some time and GDM restarts on the third graphical console (CTRL+ALT+F10).

I was not able to fully reproduce the situation every time, but it happens quite often. (The computer is regularly used by two users at the same time.) It does not seem to be connected with a single application (Firefox, Evolution, etc.) If the crash happens, it usually appears during the first minute after the second logon.

Attached please find the following info (after the crash):

Xorg.0.log.old
extended syslog (after Alt+Sys+1 and Alt+Sys+t)
lspci
lsusb
ps aux

Let me know if more information is needed.

In Ubuntu 8.10 Intrepid on the same hardware, this bug does not appear anymore.

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.
