KDE logout hang

Hello All,

I'm having trouble when logging out from a userid under Fedora 8. Here are the details.

I'm using the graphical login prompt. If I login as root, all is well. KDE comes ups and runs fine. I can then logout ( using the logout option under kmenu ) and am returned to the graphical login just fine. Subsequently I can also log in and log out as root as many times as I please. When logging out from root I observe the following:

1) Screen goes black but the mouse persists and is responsive.
2) Within 2 to 3 seconds the mouse disappears.
3) The screen briefly enters text mode and I can see a text login prompt
4) The screen returns to graphics mode.
5) The mouse appears and shortly thereafter the login screen appears

When logging out from a user account, I see item 1 as described above, but the logout process never proceeds to step 2. This state persists indefinitely. CTL-ALT-F1 works and takes me to a test login. From there I can see that X and startkde processes have zombied.

It seems that the only way out of this situation is to shutdown and reboot.

Any thoughts on what may be going on ? Thanks in advance for any help !!!

It may be that you are experiencing 'locking'. Try 'xauth -b quit'
to release any locks.

Check that your .Xauthority file gives read and write permissions to each user and not only root. It may be that your user is unable to write to the file when exiting. Search for the file but it should be in the root home directory.

I've found that there are no Xauthority files on the system. Is this a new requirement ? This machine was upgraded from Fedora 6. I suspect however that you are correct that this is a locking or permissions problem. Are Xauthority files mandatory ? Could you point me to the best source for info on the topic ? Also ... any other hints on where to look or techniques to find what X may be complaining about ? I looked in /var/log/messages and /var/log/Xorg.0.log , nothing stands out.
