Xgl: Difference between revisions

Revision as of 16:12, 8 March 2006

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.
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).
Restoring a window is not smooth and only appears when fully maximized (no smooth transition such as minimizing).
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.
