AIGLX was a project to add accellerated indirect rendering to the existing Xorg server.

As of Xorg v7.1, all the code from the AIGLX project has been merged into X.Org.

Hardware Status

AIGLX requires that your video driver support a new extension called GLX_EXT_texture_from_pixmap.

Supported Hardware

• All Intel graphics chips that use the i810 Xorg driver. (More Information)
• All nvidia graphics chips that are supported by the binary driver. See UpToDateAtiNvidiaDrivers.

Partially supported hardware

• ATI: Radeon 7000 through X850 (r100 through r400 generations), but only if using the open-source 'radeon' driver
• 3dfx: voodoo3 through voodoo5. Might need NV_texture_rectangle emulation.

Information about unsupported hardware

• The open-source ATI driver (radeon) uses software rendering for alpha (transparency). This makes Compiz unusably slow on a Radeon 9200 (one of the fastest cards supported). No word from ATI on when their proprietary driver (which has proper 3d acceleration) will support AIGLX.

There is more information about the status of video cards on the Official AIGLX Website.

If you have an ATI card, you can use UbuntuHelp:CompositeManager/Xgl in the meantime.

Installation & Configuration

NOTE: Edgy includes Xorg 7.1, which has AIGLX integrated, so it is much easier to enable AIGLX on Edgy (no additional software is required).
