ATI has released a new version of its Catalyst proprietary Display Driver for Linux. The new driver, i.e. ATI Catalyst 10.1 introduces production support for Ubuntu 9.10 Karmic Koala. It is available for both 32-bit and 64-bit systems and introduces the following fixes:

• X.Org no longer crashes on an Ubuntu 9.10 system, if multiple Xinerama-enabled X.Org server generations are executed
• Switching between virtual desktops no longer breaks the operating system
• Single mode is now shown properly in the "Display Manager Properties" tab of the ATI Catalyst Control Center, instead of multiple modes, if the "big desktop" mode is enabled
• The system no longer crashes if an HDMI monitor is hot-plugged, or if the users toggle between HDMI and LCD
• Fixed an issue on Red Hat Enterprise Linux 5.4 32-bit systems, when the "Detect Displays" button was selected in ATI Catalyst Control Center, and an HDMI display was hot-plugged.

However, many users are complaining of various problems with the new driver in Ubuntu 9.10.
