You didn't mention that the first time.  I know that there have been a
lot of problems with nVidia and KDE4, I expereinced a bunch of them
myself with my previous laptop.  My current one seems to work fine from
both KDE and Gnome.

I am not sure what he means by that.  If Gnome works but KDE does not,
would that indicate a problem with KDE and not with the underlying
authentication mechanism?

At any rate, I use both KDE and Gnome, and have had no problems logging
out of either on Jaunty.

I know that there are issues with Intel drivers (which I believe the
fixes for are in Karmic).  Perhaps it is one of the logout visual
effects that is causing grief.  I would be curious to see what happens
if you disabled all of the extra effects in KDE.

I could not make anything out of this so I have no idea what to suggest.
