May 07, 2009 -- We began talking about Intel graphics regressions in Ubuntu 9.04 back in January but for the most part that went under the radar at Canonical up until Ubuntu 9.04 was nearing release. At that point it was then explored whether greedy migration heuristics improved performance as the UXA acceleration architecture was still too problematic to enable by default. We had found that using some of the latest kernel code had improved the performance some, but still there were major regressions within Intel's new Linux driver stack.

April 24, 2009 -- As we reported in December, the Nouveau driver is available in Ubuntu 9.04. Unlike Fedora 11 where the Nouveau driver is being enabled by default on NVIDIA hardware, the Nouveau driver will be an after-installation option to Ubuntu users. In this article are the simple steps on how to enabled the Nouveau driver in Ubuntu and what you can expect from this open-source, community-spawned graphics driver.

April 18, 2009 -- In late December AMD had published open-source R600/700 3D code that also allowed for 2D and X-Video acceleration, but was not of use to end-users interested in full OpenGL acceleration. AMD had then released the R600/700 3D documentation a month later and then the R700 ISA documentation just a few weeks back. Today, however, AMD is finally pushing some workable code into a public code repository.

April 17, 2009 -- X Server 1.6 was released back in February, and there have been test releases for it going back to the end of last year, but today AMD has finally delivered support for this new X.Org server in their proprietary Linux graphics driver. Like last month with the Catalyst 9.3 release, the Linux version was not released on the same day as the Windows build, which ended up being a one-week delay. Besides X Server 1.6 support there are also a few other changes in Catalyst 9.4 worth reporting.

April 15, 2009 -- While Intel has long backed an open-source graphics driver for their integrated graphics driver, it was not up until last year when Intel released the i965/G35 documentation that there was public, NDA-free documentation concerning their newer IGPs. Later that year they then released the GMA X4500HD series and since then we have been waiting for them to push out public documentation concerning their G45 chipset. Well, Intel has finally come to the table with this documentation and it is very extensive. This documentation drop today is split into several volumes and makes up well over 1,000 pages of Intel hardware documentation and register descriptions that are available under the Creative Common Attribution, No Derivative Works license.

April 15, 2009 -- As we have outlined before and shared benchmarks of in the past, the Intel graphics driver stack has been going through some significant changes. The Intel graphics driver now has a proper memory manager in the form of the Graphics Execution Manager, there is upstream kernel mode-setting support, and a new 3D component is coming soon in the form of Gallium3D. With all of this invasive work going on, regressions are currently prevalent from stability problems to graphical corruption to slower 2D performance. While these are problems users will face with the new distribution updates in H1'09, some have been trying out different driver configurations in order to circumvent the situation. Canonical, for example, had been toying with the idea of enabling greedy migration heuristics by default.

March 27, 2009 -- While the Catalyst driver for Windows was released a number of days ago, the Catalyst Linux driver was missing. It has, however, been released today. AMD's Linux engineers ended up delaying the Catalyst 9.3 release so they could spend additional time tuning this driver, since it will be the last release that supports the R300 through R500 series as the support is being dropped. The significant feature that was pushed back into the Catalyst 9.3 Linux driver is improved Composite support.

March 20, 2009 -- Ubuntu 9.04 will be released towards the end of next month and it is picking up the Linux 2.6.28 kernel, GNOME 2.26, and other improvements like install-time support for the EXT4 file-system and some subtle improvements. When it comes to the X.Org side it is shipping with X Server 1.6 and the stabilized version of Mesa 7.3. Specifically in regards to the ATI Linux graphics, it will be shipping with an updated xf86-video-ati driver by default and Catalyst 9.4 will be an option for the user. With Ubuntu 9.04 Alpha 6 having been released last week, we have run a few benchmarks comparing the open-source ATI performance in Ubuntu 8.10 and Ubuntu 9.04 Alpha 6.

March 19, 2009 -- In this edition of the Nouveau Companion, covered is the status of this open-source NVIDIA display driver and what went on at FOSDEM with the Nouveau project status and combining LLVM with Gallium3D. Recently the Nouveau developers have been successful in using EXA acceleration on newer GeForce 9 graphics cards, backlight controls working on more NVIDIA graphics cards, and a port of the Nouveau driver to FreeBSD. Work on kernel mode-setting and proper kernel memory management is also underway.

March 18, 2009 -- This afternoon AMD has released the Catalyst 9.3 driver for Windows along with ADL, or the AMD Display Library. The AMD Display Library is a cross-platform library that provides a single SDK to access graphics hardware information. In the past AMD has provided a few SDKs for obtaining this information on Windows, but this is the first time we are seeing such support on Linux.
