As an aside, the OS I am using is Red Hat Fedore Core 3. Forgot to mention that in my previous email.

Subject: Re: [info-performer] Multipipe Initialization
Hi,<br><br>Gordon's comment is probably correct. If the system has a single<br>graphics card, then you should only be creating one pfPipe. The notice<br>you reported is usually not a meaningful one, unless you are directly<br>calling pfChooseFBConfig in your application with constraints which may<br>not be achievable. For most multi-screen PC setups, the single card<br>treats the combined screen as a single desktop, and thus you will want<br>to use either 2 windows with 2 channels, or 1 window with 2 channels on<br>a single pipe.<br><br>Hope this helps,<br>Stace <br><br>"Christopher D.

each pfPipe has just a single pfPipeWindow attached to it. Everything initializes seemingly fine until I call pfFrame() for the first time, at which time I see my full screen windows created (blank) on the uper and lower display, and then it bombs out (the screens disappear) and I get the following notice:<br>> <br>> "PF Notice: pfChooseFBConfig: failed to make configuration matching specified attributes"<br>> <br>> Below that I get a "BadWindow" message as my X calls try to operate on the lower window created. Simply going back to one pipe, one window runs fine. Here are the functions I am using to initialize performer and initialize the pfPipes and pfPipeWindows. I've looked in the Performer manual and tried to set the pipes and windows up to work properly, but obviously I am missing something.
