Shutdown/restart don't work from X

[Avi Schwartz]

For some reason shutdown/restart/log out don't work from X.  All X based
application are terminated and I am left with what looks like the root
window displaying the Heron background. To shutdown I need to switch to
a virtual terminal and shutdown from there as root.  I can also restart
gdm and then get back the GUI login screen.

Any idea how to fix this (I think) gdm problem?
