I have come to the same conclusion: KDE 4 cannot run two desktops, even when they are running on different X servers. Fortunately, I do not need two. So now I have set up two separate X screens on a single server and run Mythtv on the tv using the DISPLAY= command.<br>

</div></div>From what I understand, this is not possible with KDE4. This has something<br>
to do with two separate instances of Plasma not being able to be run at the<br>
same time.<br>
<br>
FWIW, this is the one single issue that is holding me back from upgrade from<br>
3.5.10 to 4.?. For me this issue is a show stopper as without it I cannot<br>
see any way to run an accelerate triple head setup.<br>
<br>
Suggestions I have seen are to run KDE4 on your laptop monitor and something<br>
else (FWM? Enlightenment? KDE3.5?) on the TV card output. This should work.<br>
