Yes - I don't really want that though. I have my left two monitors (my
primary workspace) as a single KDE session using Nvidia twinview (so no
xinerama here) and the right hand third display as a separate desktop. This
allows me to change the virtual workspace (or whatever compiz calls it) on
the left two without also changing the one on the third. I find this setup
makes me much more productive.

Also, I have noticed that xinerama is slower than twinview, especially for3D

How does this work for people that have a single computer with 4 keyboards,
4 mice and 4 monitors providing a separate independant desktop to four
people? Can they not use KDE4?

I think I may using a different WM for the third monitor. That's a shame
though as it won't look or feel consistent. The third monitor is the one I
put Superkaramba on and from what I've read I'll replace this with
Plasmoids (or whatever they're called). That's not going to work if it's
not running KDE.
