In a previous article we stated:
"Highlights of the Linux AMD Catalyst™ 11.4 release include: This release of AMD Catalyst™ Linux introduces support for the following new operating systems Ubuntu 11.04 support (early look) SLED/SLES 10 SP4 support (early look) RHEL 5.6 support (production)"
AMD introduced a new feature into Linux with Catalyst™ 11.4, PowerXpress.
- PowerXpress: Will enable certain mainstream mobile chipsets to seemlessly switch from integrated graphics to the dedicated graphics. *note: This only applies to Intel Processors with on chip graphics and AMD dedicated graphics and must be switched on by invoking switchlibGL and switchlibglx and restarting the Xorg server.
If you are running RHEL 5.6 or SLED/SLES 10 SP4 and need the driver you can get it here.
If you are running Ubuntu 11.04, install the driver under the "Additional Drivers" program.
If you are running a BSD variant you must still use the Open-Source driver "Radeon" and "RadeonHD" as AMD has yet to release a BSD driver.
Be sure to check back to PCPer for my complete review of the 11.4 driver and PowerXpress.
