Hi Christoph,

I just added this to the FAQ:

I am unable to open a graphics window. I get the following exception: "pygame.error: Couldn't find matching GLX visual"

An attempt was made to open a graphics window, but the requested mode was not found. Try setting the total bit depth to 0 and each RGBA component to 0 to allow automatic matching. Start with a small window (e.g. 640x480) and do not try fullscreen initially.

Let us know of your success. You could also try other SDL-based apps (especially SDL/OpenGL). If they work, so should the Vision Egg.

I don't know where the "unknown chip id, assuming full radeon support" message is coming from. My guesses are a) SDL and b) XFree86 radeon drivers. (It's not the Vision Egg.) It doesn't seem like that message is an error - probably just information for you.

Cheers!
Andrew

Hi Andrew
I "successfully" upgraded from RH8.0 to RH9.0 in the hope, that with the
lateste xfree86, I can get the vsync working with my radeon FireGL7800.

Unfortunately I get the following error, after calling some simple ve
code, which previously worked on Rh8.0: "unknown chip id, assuming full
radeon support"

Please could you see, if there is any update on the VE side necessary,
or if I need to do something on my system.

Thanks a lot
