Xgl

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.

1. Enabling FSAA causes corruption and instability.
2. Mesa library is required for pixmap_to_texture support.
3. Screen limit of 2048x1024 (so no dual screen)
4. Closing the Xgl server without restarting X will cause a hardlock.
5. Restoring a window that has been minimized sometimes causes the window to not be fully redrawn (random percentage is not redrawn, or sometimes the whole window is drawn).
6. Restoring a window is not smooth and only appears when fully maximized (no smooth transition such as minimizing).
7. On ATI cards, Xgl can only be started with a higher display number than the Xorg it is running on, i.e. DISPLAY=:0 Xgl :1 will work, DISPLAY=:93 Xgl :0 will not.

See also the openSUSE wiki for workarounds about some of the driver bugs.
