The system in question is a dual Xeon system running Fedora-11 with all updates
to 2009-07-22. Graphics board is an ATI RV280 [Radeon 9200 PRO].
I have some applications installed from rpmfusion including paraview.

Currently if I run paraview, X goes to 100% and I can no longer
operate the system via mouse/keyboard. Via a network login I
can "killall -9 X" but that does nothing to X. I have also
tried killing paraview in the same way with no effect (possibly
after trying to kill X).

I know 3D is horribly broken in F11 :( as well as many other things,
but I would have thought that kill -9 should still work ...
