For those that may have missed it, the ATI/AMD fglrx 8.42 display driver that was released last month had introduced AIGLX support. The open-source "Radeon" driver for ATI graphics cards going up to the R400 generation has supported AIGLX for quite some time, but the ATI binary display driver hadn't until last month. However, one of the complaints about the fglrx implementation of AIGLX is that in the 8.42.3 driver, some are encountering slow performance in Compiz / Compiz Fusion. We have taken an ATI Radeon X800XL 256MB PCI-E graphics card, which is supported by both the Radeon and fglrx drivers, and have compared their Compiz performance in a few different scenarios.

Since AMD introduced their new Linux display driver last month, we have published a number of different articles looking at the Radeon performance across their different GPU product generations. This ATI/AMD Linux driver testing and exploration continued this month with the release of the 8.42 driver, which finally introduced AIGLX support for the fglrx driver. One area though we haven't yet analyzed is how their official Linux driver now compares to their much-optimized Windows Catalyst driver. Today, however, we will be looking just at that as we compare the ATI Radeon HD 2900XT 512MB performance under Linux and Microsoft Windows Vista.

In this edition of the Nouveau Companion, the developers of the open-source 2D/3D NVIDIA display driver talk about IRC color coding, NV04 performance improvements, texture fixes, EXA advancements, register combiners, and more. Also being worked on by the Nouveau camp has been a NV4x TTM and Gallium prototype. The Nouveau developers are still in need of some additional testing, so be sure to give them a hand if you're able to do so.

This past Sunday we started our first-ever Linux Graphics Survey that looked at the usage of X.Org display drivers, hardware, and the display features being sought after by Linux desktop users. In less than four days, we received over 10,000 survey submissions! This survey will be going on until November 21, so if you haven't yet participated you still have plenty of time to do so. But for those of you that have already taken the survey, what are the results so far? Well, below are the percentages from all of the responses collected before 10:00AM PST today. In Late November when the survey has ended, we will present the final results.

Today it's now time where the fglrx driver reaches yet another milestone. Not only does today's release address many of the outstanding bugs for the earlier GPU generations while also introducing a few new features, but it also delivers AIGLX support! Yes, you read that right. You can finally run your ATI graphics card with the fglrx driver and run Compiz, Beryl, or Compiz Fusion without using XGL! This is coming 13 months after NVIDIA had introduced its AIGLX support, but now just days after the release of Ubuntu 7.10 Gutsy Gibbon it's here for ATI hardware. Granted, if you were using an older ATI GPU with the open-source Radeon driver, you could have been benefiting from AIGLX already.

While Linux desktop surveys are nothing new, no recent polls have looked specifically at Linux graphics when it comes to X.Org video drivers, hardware, and related video features. We, however, at Phoronix see a need for this information to be profiled and have launched the first-annual Linux graphics survey. This survey is intended to allow the development community to get a better understanding of the video hardware in use, what open-source and closed-source drivers are being used, and other relevant information.

It's time for another issue of the Nouveau Companion, which talks about the development work done on the open-source 2D/3D NVIDIA driver over the past two weeks. Among the topics talked about in this issue include PlayStation 3 graphics via Nouveau, using TTM memory manager, and the Gallium3D architecture. A stable 2D Nouveau driver is about completed with EXA support but currently lacks an EXA implementation on the older NVIDIA hardware and there are still problems with NVIDIA's GeForce 8 hardware.

It's going on two weeks since the RadeonHD driver was made available, which is AMD's sanctioned open-source driver for the Radeon X1000 (R500) and Radeon HD 2000 (R600) series (as well as future generations of AMD GPUs). In this time, we have seen some great progress made with this open-source driver and have a few additional remarks to share about its status and the first bits of this driver's roadmap.

It's been about a month since the last Nouveau Companion, the development newsletter talking about the work going into the open-source 3D NVIDIA display driver, but today the latest edition is now available. Covered in the 27th edition of the Nouveau Companion are details on the progress made in the past month such as with porting the driver to using libpciaccess, bug squashing, 2D acceleration working for NVIDIA's GeForce 8800GTX, X-Video fixes, and RandR 1.2 support was merged back into the Nouveau master branch. The Nouveau developers have received a few new graphics card donations but are still in need of development help and testing.

This past week was marked by the release of the NVIDIA 100.14.19 display driver for Linux and Solaris, which was the first alternative OS driver release from this Santa Clara company in about three months. The public change-log is quite lengthy and finally delivered on fixing the GeForce 8 performance regression. In our GeForce 8800GTS Linux tests, the performance fix was very evident. However, now that we have had the time to run more extensive tests with the GeForce 8 series and this new driver, we have found not everything to be smooth sailing.
