Gentoo Linux ATI FAQ Luca Barbato Jorge Paulo Tiemo Kieft Joshua Saddler This FAQ should help users avoid some common installation and configuration issues related to DRI and X11 for ATI boards. 1.6 2007-11-29 Hardware Support
Is my ATI board supported?

Many ATI boards (but not all) are supported by xorg-x11, at least for the 2D accelerated features. The 3D support is provided either by xorg-x11, or by ATI's closed source drivers.

GPU Common Name Support
The HD 3000 series cards are based on the R600 chip, but there is currently no support in Linux for these cards. The open-source RadeonHD driver is expected to support these cards in the future, though the driver is currently under heavy development. ATI is expected to release an updated fglrx driver version with 2D/3D hardware acceleration.
I have an All-In-Wonder/Vivo board. Are the multimedia features supported?

The board's multimedia features are supported by the GATOS project. These drivers have been merged into the Xorg tree. You don't need to use anything special; x11-drivers/xf86-video-ati will work just fine.

I'm not using an x86-based architecture. What are my options?

X11 support on the PPC or Alpha platforms is quite similar to x86 X11 support. However, ATI's closed source drivers are not supported on the PPC or Alpha, so you cannot use the 3D features of the R300 Graphics Processing Unit (GPU). If you have such a board and want it supported by X11, contact ATI and ask them to release the specifications for your system's GPU. The closed source driver for the AMD64 was released, so AMD64 users can now enjoy the same features as x86 users.

To enable agpgart support for certain AMD64 chip sets, you have to disable support for the K8 IOMMU.
I have a laptop. Is my ATI Mobility model supported?

It should be, but you may have a configuration issue due to the OEM PCI id that such chips may have. In most cases, you may have to write the configuration file yourself or use the xorgconfig utility.

Installation
Packages

There are two ways of getting drivers for your ATI card:

  • The xorg-x11 ebuild provides the X11 implementation
  • The ati-drivers ebuild provides the ATI closed source X drivers and kernel modules

If you want to use ATI's internal agpgart support instead of the Linux kernel one, the agpgart driver and the chip set specific driver (in your kernel configuration) must be built as modules or not at all.

Please read the Hardware Acceleration Guide for more information on installing drivers for your ATI graphics card.
Configuration

The use of xorgcfg or xorgconfig to generate the xorg.conf configuration file is suggested. Alternatively, you may use the Xorg auto configuration option:

# X -configure

For more information on how to get a basic xorg.conf configuration file, please refer to the Gentoo X Server HowTo.

You can use aticonfig if you have installed the ati-drivers package. PPC users could use the Xorgautoconfig stand-alone configuration tool by emerging the Xorgautoconfig ebuild, but isn't required.
Switching to OpenGL

Once X is installed, configured, and running, it can use the ATI OpenGL libraries:

# eselect opengl set ati
