Chapter 23 . Gaming with Linux 623 now use X.Org). Resulting video driver modules may be specific to the Linux kernel you are running. So, know that if you upgrade your kernel, you might need to reinstall your video driver as well. The rpm.livna.org site has greatly simplified the process of installing ATI and NVIDIA drivers for Fedora Core and other Red Hat systems. Refer to the Livna Switcher page (http://rpm.livna.org/livna-switcher.html) to learn how to install RPM packages containing the ATI or NVIDIA drivers you need. If you load a binary-only driver, it does what is referred to as tainting the kernel. As a result, you won t be able to get support if you run into problems (at least from kernel.org) because, lacking the source code, it is hard to debug driver-related problems. Also, binary-only drivers are known to cause obscure problems because they get out of sync with kernel code changes. Similarly, binary-only drivers aren t updated as frequently as the kernel. While many people, including myself, use binary-only drivers in special cases, they do have shortcomings that you should be aware of. Open Source Video Drivers If you want to use open source drivers for 3D accelerated gaming, whether you are running the games using Cedega or natively in Linux, look for cards that have drivers that support OpenGL. The DRI project is one initiative that is creating OpenGL driver implementations. Following is a list of video card manufacturers that have DRI video driver support available. The list is from the DRI project site (http://dri.sourceforge.net/). . ATI Technologies You don t have to use binary-only drivers to get 3D acceleration for some ATI video cards with open source drivers. Chip sets from ATI Technologies that support DRI include the Mach64 (Rage Pro), Radeon 7X00 (R100), Radeon 2 / 8500 (R200), and Rage 128 (Standard, Pro, Mobility). Cards based on these chip sets include All-in-Wonder 128, Rage Fury, Rage Magnum, Xpert 99, Xpert 128, and Xpert 2000. . 3dfx If you can find a used unit on eBay (3dfx is no longer in business), there are several 3dfx cards that support DRI. In particular, the Voodoo (3, 4, and 5) and Banshee chip sets have drivers that support DRI. Voodoo 5 cards support 16 and 24 bpp. Scan Line Interleaving (SLI), where two or more 3D processors work in parallel (to result in higher frame rates) is not supported for 3dfx cards. . 3Dlabs Graphics cards containing the MX/Gamma chip set from 3Dlabs have drivers available that support DRI in Linux. . Intel Supported video chip sets from Intel include the i810 (e, e2, and -dc100), i815, and i815e. . Matrox The Matrox chip sets that have drivers that support DRI include the G200, G400, G450, and G550. Cards that use these chips include the Millennium G450, Millennium G400, Millennium G200, and Mystique G200. Caution Note
