Hi, I have just completed the installation of the Vision egg package on a system running RedHat 8.0. Though it was not especially easy, all of the required packages are now installed. However, none of the Vision egg demos will run. I get an error message which says: pygame.error: Couldn't find matching GLX visual I'm not sure how to proceed since pygame installed successfully. Also, I have run demos (not pygame or Vision egg) which require GLX. Any suggestions? Thanks, Roy -- R.E.
