Interesting. My first guess would be that Performer is now trying to
get the same visual for both screens, and it's unable to do that,
because the second screen won't have GLX support, and therefore, won't
have as many visuals available. I could be totally wrong here, however.
You may be able to explicitly request a different visual for each
window. If you run the glxinfo commands I mentioned in my previous
e-mail, you'll be able to see which visuals are available on each
screen. Then, you can use pfChoosePWinFBConfig() on each window to
select visuals that you know are available.
In any case, the easiest solution would be to reconfigure your X desktop
to use a single screen, and redo your application to have a single
pfPipeWindow, and multiple pfChannels instead. This way, both physical
screens will benefit from hardware GLX and you'll only need the one window.
