Xgl
From cchtml.com
Xgl is the GLX on OpenGL implementation by David R. at Novell.
fglrx works for the most part, but there are a few bugs known to exist.
- Enabling FSAA causes corruption and instability.
- Mesa library is required for pixmap_to_texture support.
- Screen limit of 2048x1024 (so no dual screen)
- Closing the Xgl server without restarting X will cause a hardlock.
