Word is breaking today on the Windows-focused web-sites that AMD's Catalyst driver program has fundamentally changed. How does this impact Linux Catalyst users? Unfortunately, it will likely prove to be in a bad way.
AMD admits it has had some Linux support problems with its graphics drivers and they'll be working to improve the situation.
For those disappointed by the results of the open-source vs. closed-source AMD Radeon graphics driver results on Linux at this time, you may be more pleased going forward and carry hope for open-source AMD advancements in 2013.
If you happen to be an unfortunate soul still using an old ATI Rage graphics processor, the "R128" driver now has EXA acceleration support after about a decade and a half of the hardware being around.
AMD has brought back the gDEBugger software to Linux.
Yesterday while the Phoronix server infrastructure was being hammered by the exclusive Valve Linux work, AMD released their Catalyst 12.4 Linux driver.

AMD has officially released Catalyst 12.3 for Linux as its March 2012 update for those relying upon this binary graphics driver.
Tom Stellard of AMD has called upon the LLVM developers to include the R600 GPU back-end into the LLVM project, which is the code for generating compute and graphics shaders inside the LLVM compiler infrastructure for targeting Radeon HD 2000 through HD 6000 series graphics processors.
As Phoronix Forums readers have been quick to discover, early "beta" builds of AMD's Catalyst 12.3 proprietary Linux driver have begun to appear publicly.
AMD has finally released the open-source driver code to support the Radeon HD 7000 "Southern Islands" GPUs and next-generation Fusion "Trinity" APUs under Linux with their open-source driver.
AMD has released their belated Catalyst 12.2 Linux driver today. Unfortunately, it's not too exciting of a release.
Yesterday AMD officially launched the Radeon HD 7800 "Pitcairn" series as the latest hardware in their Southern Islands family to reside between the Radeon HD 7700 series and their flagship Radeon HD 7900 cards. Unfortunately, the open-source support for these latest AMD GPUs remains unavailable.
While most Linux enthusiasts know by now that there still isn't open-source Radeon HD 7000 series support from AMD under Linux, the Catalyst situation isn't so clear. While they've been committed to launch-day Catalyst hardware enablement under Windows and Linux, for the penguin OS that doesn't seem to always be the case for the HD 7000 series.
Christian König of AMD has shared his plans for completing work on the VDPAU state tracker for Gallium3D. This Gallium3D state tracker allows for NVIDIA VDPAU video acceleration using GPU shaders on open-source hardware drivers such as Radeon and Nouveau.
For those AMD Catalyst users that were concerned by the recent statements of Martin Gräßlin that KWin will likely end up dropping their GL1 renderer, which would eliminate vintage GPU hardware support as well as Catalyst driver support, fear not.
AMD today launched the Radeon HD 7570/7770 graphics cards as the latest GPUs built on the GCN architecture. Unfortunately there still is not any open-source support for the Radeon HD 7000 series hardware nor has AMD sent out any review samples to Phoronix. But there is some other Catalyst Linux news to share.
AMD has unleashed the first Catalyst Linux binary driver update of 2012, but does Catalyst 12.1 bring anything interesting or just more breakage?
The XBMC multimedia project has implemented AMD's XvBA interface directly for providing video hardware acceleration for Radeon and Fusion graphics processors.
A new version of AMD's Catalyst Linux graphics driver is now available.
