Xgl can perform intricate graphical operations--such as rendering antialiased fonts--noticeably faster than other available Xservers that do not use OpenGL.
This video-hardware is known to work well or recommended for use with XGL. Please add exceptions if there are any.
All intel graphics chips need the newest packages of Xgl and compiz for running flawlessly. Please wait for SL10.1 rc1.
o i915, i945
Accelerated XVideo is broken on these cards. See Troubleshooting.
All NVIDIA cards need the proprietary driver for running Xgl. With Beta8, you will need to uninstall and reinstall the xgl rpm after installing the proprietary NVidia driver.
o GeForce 4xxx series
XVideo is not accelerated on these cards.
o GeForce FX 5xxx series, Quadro FX series
Accelerated XVideo is hitting a slow path on these cards, it is under investigation.
o GeForce 6xxx series
o GeForce 7xxx series
o Mobility Radeon 9700 SE: Xgl running with proprietary fglrx driver 8.23
If your card isn't listed then you can check out the Gentoo hardware list as well.
Hardware with known glitches or incompatibilities:
o Mobility Radeon M6 LY (7000), Mobility Radeon M9 (9000) and Mobility Radeon M9+ (9200)
Drawing artifacts and occasional flickering.
o Radeon 9200
No hardware acceleration using fglrx 8.22.5 driver.
Works, but compiz may crash on startup, and effects are overall very slow.
o i815, i845, i855
Too old, Xgl works, but compiz will not work. Maybe a compatibility layer is added later.
