Yes, that's working for me also. I am now suspicious that previously I
might have set the 'Switch to Screen 0/1/2' instead of 'Window to
Screen 0/1/2' setting as the setting you call out now is working and I
don't remember working at the bottom of the list earlier. Anyway, it
works. Thanks.

Be careful about port assumptions. As you run Radeon (I think) it
could certainly be different but my 3 port NVidia cards really only
support 2 monitors. If I was to use the Display port I'd lose one of
the DVI.

For me to get to 3 monitors here I had to install a second card (also
NVidia) which has unfortunately limited my options WRT OpenGL, etc.
None of the KDE features that do things like show all 6 Desktops work
on my server which has 3 monitors split across 2 cards. There's a
bunch of info on the web about how this is a known limitation, etc.,
so I haven't fought it at all. Apps like xine work perfectly on
Screens 1 & 2 but display a black box on Screen 3. (Audio still
available.) Still, I do most multimedia on Screen 3 using a Windows XP
VM in VMWare running NetFLix/Hulu, etc. Note that the most recent
versions of Virtualbox don't seem to work for this feature saying they
cannot lock the screen or some other such DRM-ish message.

So far, if I was insistent about getting OpenGL working on 3 monitors,
and based on my current skill set, I'd go look for a new VGA card that
supported 4 monitors as it allows the whole OpenGL graphics space to
be in the memory on one card. I believe I read that works fine, as it
does on 2 monitor cards.

On the other hand, and from a COMPLETELY selfish point of view, if you
want to get a second VGA card and pound these OpenGL problems into
submission I'll GLADLY follow along in awe as you fix my problems
also! ;-)

Thanks for the help!
