Jason-
I am going to take a step back from my "multiscreen" view and see about attacking the problem with one "screen" covering both LCD displays, ie setting up my system with one "screen" instead of 2..
So far I have one pipe, with two windows attached to it and channels set in the windows. I have noticed that when I created the 2nd window, what gets displayed in each window now looks "funky", with colors being off and some things not showing up or updating. What else needs to be done to get 2 windows to "play nice"? I've read about pfPWinShare() and the associated funcitons but don't have an example of how configuring, framebuffering, and relying on calls to pfFrame() should be set up. I suspect that may be my problem.

initPipeWindow(void)
{
int constraints[] = {
PFFB_DOUBLEBUFFER,
PFFB_RGBA,
PFFB_RED_SIZE, 5,
PFFB_GREEN_SIZE, 5,
PFFB_BLUE_SIZE, 5,
PFFB_ALPHA_SIZE, 1,
PFFB_STENCIL_SIZE, 8,
PFFB_DEPTH_SIZE, 15,
(int)NULL
};

mttGlobal->gfxPipeLOWER = pfGetPipe(0);
if (!(mttGlobal->gfxPipeLOWER)) {
fprintf(stderr, "ERROR: Unable to initialize LOWER (pfPipe *)!\n");
abort();
}
/*mttGlobal->gfxPipeUPPER = pfGetPipe(1);

pfPipeScreen(mttGlobal->gfxPipeLOWER,0);
/*pfPipeScreen(mttGlobal->gfxPipeUPPER,1);*/
mttGlobal->pwinLOWER = pfNewPWin(mttGlobal->gfxPipeLOWER);
