Question about X11DRV_ChoosePixelFormat glXChooseFBConfig returns NULL (glError: 0)

[L. Lenders]

Just for the info: after some digging i found a quick
hack to get rid of the error: comment line 208 in
dlls/x11drv/opengl.c:

//TEST_AND_ADD1(ppfd->dwFlags & PFD_STEREO,
GLX_STEREO);

Somehow setting the PFD_STEREO flag makes doom3 crash
and triggers the error mentioned in the subject.
After commenting line 208 doom3 starts up just fine.
Digging further.....  :)
(any help appreciated) Louis
