ATI Linux fglrx driver version 8.39.4

Release Date: 23 July, 2007

Issues Resolved

  • The kernel module build no longer fails on kernel version 2.6.22. Further details can be found in topic number 737-28556
  • Starting AMD CCC-LE no longer fails with a floating-point exception when started in certain configurations. Further details can be found in topic number 737-28557
  • When playing videos in I420 color format using the Xv extension and TexturedVideo (the default on R5xx), colors are no longer displayed incorrectly. Further details can be found in topic number 737-28558
  • Running aticonfig --initial in X with the Vesa driver no longer segfaults resulting in the xorg.conf file not being available. Further details can be found in topic number 737-28559

Known Issues

  • Video Tearing may be seen during playback in XV using GLESX. Further details can be found in topic number 737-26984
  • A black screen may be observed on some hardware when switching to the console or leaving the X window system when a Vesa framebuffer console driver is used. Further details can be found in topic number 737-28558
  • Corruption may be observed with certain applications on some Linux distributions which enable the Composite extension by default, e.g., RHEL 5. If you are observing application corruption, please disable the Composite extension. Further details can be found in topic number 737-28224
  • Using the xgl enabled x-server interface disables display switching hot plug support
  • There is no support for video playback on the second head in dual head mode. Further details can be found in topic number 737-26985

Feature Wish List

The following features are still not supported properly by ATI's driver:

  • Composite Extension: The ATI driver is far behind other open source Xorg drivers in supporting Composite extension. Clearly they are not keeping up and will benefit significantly by releasing their source code under GPL or BSD or MIT license.
  • Removing the need to enable module support in the kernel to fully install the driver. It will work without it, but that doesn't enable DRI. This is possible by releasing their source code under the GPL license, and creating a patch for the kernel.
