Introduction

x11-drivers/ati-drivers (often referred to as "fglrx", the name of its kernel module) is the proprietary, accelerated driver for AMD (ATI) graphics cards.

Preparing to Install

Configuring the kernel

[*] Enable loadable module support
Processor type and features --->
      [*] MTRR (Memory Type Range Register) support
Bus options (PCI etc.) --->
      [*] PCI Express Port Bus Support
      [*] Message Signaled Interrupts (MSI and MSI-X)
Device Drivers --->
      Graphics support --->
            < > Direct Rendering Manager (xFree86 4.1.0 and higher DRI support) --->

   Note

If you need support for AGP cards, enable the following kernel options:

Device Drivers --->
      Graphics support --->
            <*> /dev/agpgart (AGP Support) --->
                  Select an appropriate AGP driver:
                  <*> AMD Opteron/Athlon64 on-CPU GART support

Editing make.conf

Add the following to your /etc/make.conf:

root # nano /etc/make.conf
VIDEO_CARDS="fglrx"

Editing package.use

Then, add the following to /etc/portage/package.use:

root # nano /etc/portage/package.use
x11-drivers/ati-drivers qt4

USE Flags

Use flag	Default	Recommended	Description
debug	No	?	Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces, see http://www.gentoo.org/proj/en/qa/backtraces.xml
modules	Yes	Yes	Build the required kernel modules.
multilib	Depends on system	Depends on system	On 64 bit systems, if you want to be able to compile 32bit and 64bit binaries. Not recommended for pure64-based builds.
qt4	No	Yes	Add support for the Qt GUI/Application Toolkit version 4.x. This use flag also enables the building of amdcccle (AMD Catalyst Control Center: Linux Edition).
static-libs	No	No	Buold static versions of dynamic libraries as well.

Installing

Emerging the package

To emerge the drivers, run the following command:

root # emerge -av --changed-use --deep @world

Configuring

Next, set ati-drivers to manage the system's OpenGL implementation:

root # eselect opengl set ati

Afterwards, run aticonfig to modify the X-server configuration file to work with the ati-drivers:

root # aticonfig --initial

Troubleshooting

I am using a HDMI connection, and my monitor's display has a black border around it.

Disable overscan using the following command, as root:

root # aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0

You may need to restart your X session.

GNOME 3 windows only refresh when I drag them.

This is a known issue, reported in Funtoo Bug 1130. This issue has been fixed by addressing a bug in cogl -- upgrade to cogl-1.12.2-r2 to fix it.

Compton with backend glx does not work well with ati-drivers

Try running compton with the following switches:

root # compton --backend glx --vsync none --paint-on-overlay
