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

Adding the qt4 USE flag enables support for building of amdcccle (AMD Catalyst Control Center: Linux Edition).

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
