[Hardy] KDE sometimes hangs on logout

[Geir Ove Myhr]

Binary package hint: kdebase-workspace

Every once in a while, when logging out from KDE in Hardy, the monitor goes black, except for the mouse pointer which is still moving. I have seen this problem on several (identical) computers.

Last time it happened I captured all the relevant information that I could think about:
- output of `ps aux`
- /var/log/Xorg.0.log
Then I did a Ctrl+Alt+Backspace, which took me back to a text terminal, but gdm did not restart (the Xorg process was listed as <defunct> afterwards. Same output collected when this happened. I'll also attach ~/.xsession-errors, but the timestamp seemed to be from well before I logged out.

One issue that may complicate things: The computers have NFS-mounted home directories. I know network problems can sometimes lead to strange behaviour when the NFS server doesn't reply. In this case the NFS mounted directories looked fine when I ssh'd in.

Is there anything else I can try to capture when this happens next time, to find out what goes wrong?

If this is still an issue in Kubuntu 8.10 or 9.04, could you please attach a copy of /var/log/Xorg.0.log after a failed logout? Thanks in advance.

No, the computers are on Hardy LTS for stability. I have tested Intrepid and Jaunty on the computers, but since this happens quite rarely, I haven't had the problem happen on any of those. I guess this isn't much to work with for troubleshooting, so this bug report can probably be closed.

Unfortunately it isn't much for trouble shooting. :)
If this issue re-occurs with a newer version of Kubuntu, please feel free to reopen this report.
