[pygame] PyOpenGL and win32screensaver

[Ken Seehart <ken@xxxxxxxxxxx>]

I am trying to get a 3D screensaver to work using PyGame, PyOpenGL and 
win32screensaver.  There seems to be an incompatibility that I haven't 
been able to resolve.

Since win32screensaver invokes a special instance of pygame, I know I 
can't import pygame myself or use pygame.display.set_mode without 
extreme care.  So I tried changing win32screensaver to have a 
configurable video_flags parameter.

So pyscr_pygame.py[86] has:
  self.window = self.pygame.display.set_mode((self.width, self.height), 
self.video_flags)

Now I set video_flags to 0x40000002 (that's OPENGL|DOUBLEBUF, but of 
course I can't import pygame, so for now I just hard code it, until I 
get something working).  Apparently the OPENGL flag is killing it.  If I 
use the OPENGL flag, the process hangs during initialization (before the 
first draw is attempted).

What kind of side effect should I expect from the OPENGL flag?  Any 
ideas/workarounds?

Should I try taking PyGame out of the loop?  Neither PyOpenGL and 
win32screensaver actually require PyGame, but PyGame seems like it 
should be a convenient glue between the two.  Besides,  I have be able 
to make my PyOpenGL content work under PyGame, and I have successfully 
used win32screensaver with Pygame (without PyOpenGL).  It would be nice 
to be able to do both at the same time.

Happy Everything,
