AMD 8.42 Driver Brings Fixes, AIGLX!
 

Today it's now time where the fglrx driver reaches yet another
milestone. Not only does today's release address many of the outstanding
bugs for the earlier GPU generations while also introducing a few new
features, but it also delivers AIGLX support! Yes, you read that right.
You can finally run your ATI graphics card with the fglrx driver and run
Compiz, Beryl, or Compiz Fusion without using XGL! This is coming 13
months after NVIDIA had introduced its AIGLX support, but now just days
after the release of Ubuntu 7.10 Gutsy Gibbon it's here for ATI
hardware. Granted, if you were using an older ATI GPU with the
open-source Radeon driver, you could have been benefiting from AIGLX
already.
