The Catalyst 11.4 Linux driver also offers the first bits of AMD PowerXpress support under Linux, but it's clunky in that the X.Org Server needs to be restarted when switching graphics adapters. This implementation is meant for switching between Intel and ATI Radeon graphics.
This driver also provides support for Red Hat Enterprise Linux 5.6 and SuSE Linux Enterprise Desktop 10 Service Pack 4. The Catalyst 11.4 Linux driver also has at least one fix for Wine.
The Catalyst 11.4 driver can be downloaded at AMD.com for Windows and Linux.
