->What I would need is a list of all the actual possibilities of frame buffer
->configurations adressed by the Performer function pfPWinFBConfigAttrs with such
->an iR configuration.
Use the shell command glxinfo to get a listing of all visual types
on the machine.
When you specify an attribute array as below, we send it directly to
glXChooseVisual(). Currently, if that fails, we just try our
normal default visual scheme described in the pfAntialias and pfWindow
reference pages. In the future we'll try to do something a little more
helpful in this case but right now at least it is simple.
->
->So far, I have tried :
->int FBAttrs[] =
->{
-> PFFB_RGBA,
-> PFFB_DOUBLEBUFFER,
-> PFFB_DEPTH_SIZE, 23,
-> PFFB_RED_SIZE, 8,
-> PFFB_GREEN_SIZE, 8,
-> PFFB_BLUE_SIZE, 8,
-> PFFB_ALPHA_SIZE, 8,
-> PFFB_SAMPLES, 8,
-> PFFB_STENCIL_SIZE, 1,
-> None,
->};
->
->And the result is : "pfChooseFBConfig: failed to make configuration matching
->specified attributes". What can be wrong?
Check this request against the visuals listed by glxinfo.
You probably don't have a 23bit depth and 8 multisample doublebuffered
visual. This will be fixed in future iR releases.
