Are you using XWin or XWin_GL, the version with accelerated OpenGL. For XWin_GL
you'll need additional OpenGL drivers from your vendor. The drivers installed by
Windows will not work properly.
To test you should run glxinfo | grep "OpenGL vendor string".
If this is something like "Windows GDI" then you're using the Windows supplied
drivers which do not work.
Another good program for testing is glxgears. It is installed with Cygwin/X and
should always show running gears.
