What works even better

[Neal Becker]

Interestingly, since installing Fedora F11 IIRC, I have not been able to get
nx to work with kde sessions. It only worked with gnome. This was true both
on non-free nx, and with freenx.

Surprisingly, neatx works fine with kde.

Problem was, session would start, but it was impossible to give input focus to
any window.

I'm delighted to hear neatx is working for you -) The difference
probably just comes down to the configuration in this case - neatx
uses '/etc/X11/Xsession startkde' to run kde (as can be seen from
neatx.conf), which could well be working around the pitfall the other
two are hitting.
