The following section provides a brief description of known issues associated with the latest version of ATI Catalyst Linux software suite. These issues include:

• Killing X-server after resuming from hibernation may cause the system to stop responding
• System may fail to display error message when improper position values are used in "aticonfig --tv-geometry" resulting in invalid "TVHPosAdj" and "TVVPosAdj" values in xorg.conf file
• Rotated screen may fail to properly restore after running full-screen OpenGL application in dual-head mode; a switch VT will restore screen correctly
• Mouse cursor might be blocked from entering the taskbar area after applying specific rotations
• Significant delay may be observed while rotating screen with XRandR
• Segmentation fault may occur when running "Quake 4" and "Enemy Territory: Quake Wars" at 1280x1024 or resolutions higher than current desktop resolution

Note: On Novell's openSUSE, SLED and SLES operating systems running “sax2” or “sax2 -r” on the console overwrites the X.Org configuration file xorg.conf, reverting changes made by running “aticonfig --initial”. As a result subsequent X session may start up using the open source ATI Radeon on X-Vesa graphics drivers instead of the proprietary ATI Linux Graphics Driver. Solution: Do not use Sax2 when the proprietary Linux Graphics Driver is installed. Instead configure all display parameters using the ATI Catalyst Control Center--Linux Edition or the aticonfig command line interface.
