I have a user whose desktop is frozen. We're running Redhat 5.8. Gnome version is 2.16.0.
Clicking the icons does nothing. The menus on the toolbar work. If I try to launch nautilus from the command line, the process starts, but nothing appears.
It appears to be a configuration issue. I killed the entire session and started a new one, but that didn't fix the problem.
For what it's worth, everything is accessed by VNC.
UPDATE: The errors in .xsession-errors are uninformative, insofar as I have the same errors on my account, and there's nothing wrong there.
Very strangely, if I put absolutely everything except .cshrc and .vnc into a dummy folder, then start VNC (and hence a desktop session), the problem persists! I have no idea how that could happen, since there's nothing unusual in his .cshrc or .vnc/xstartup files.
