Summary: Accelerated ATI/AMD binary drivers for Radeon HD 5000 and newer chipsets.
- Install qt4 dependent optional tools (e.g Catalyst Control Panel)
- Build the kernel modules
- Do a potentially dangerous binary search and replace to disable watermark
- Enable pax kernel specific patches
- Enabled Video Acceleration API

AMD Catalyst Video Drivers
Version 14.12-r3 and above now include ATI GLESv2 and EGL libraries, which should improve stabilty with GNOME.
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
Blacklist Radeon and DRM Modules
To avoid having the open source Radeon drivers automatically load and ruin your day, create a blacklist file as follows:
Configuring the kernel
Configure the kernel as follows. Note that the Direct Rendering Manager is not enabled. It's possible to have it selected as a kernel module, but should not be built-in to your 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) --->
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
Add the following to your
# nano /etc/make.conf VIDEO_CARDS="fglrx"
Enabling AMD Catalyst Control Center
Then, add the following to
/etc/portage/package.use if you would like to enable support for AMD Catalyst Control Center:
# nano /etc/portage/package.use x11-drivers/ati-drivers qt4
If you are using a desktop or workstation profile, this USE flag will be enabled by default.
Emerging the package
If you allready have emerged xorg-server, all you need to install the drivers is running the following command:
# emerge -av --changed-use --deep @world
otherwise you may install the drivers with
# emerge -av x11-drivers/ati-drivers
Before using the driver, ensure that the "fglrx" module has been loaded -- run
modprobe fglrx as root -- it should return with no error. If the module can't be found, run
depmod -a as root -- then the modprobe command should work. If you are switching from the open source Radeon driver, then shutting down your desktop and rebooting your system (be sure to disable xdm) may be required to get the new "fglrx" module to load cleanly.
Next, set ati-drivers to manage the system's OpenGL and OpenCL implementations:
# eselect opengl set ati # eselect opencl set amd
aticonfig to modify the X-server configuration file to work with the ati-drivers:
# aticonfig --initial
If you would like to have a full-resolution framebuffer with ati-drivers, check out uvesafb
There are a couple of options for setting up a multi-head display. For some systems, all you need to do is plug in your additional monitor, and it will be detected by your desktop environment, and will work.
If your second monitor does not display anything at all, then play around with your X configuration. Try using the following command to generate a new X config:
# aticonfig --initial=dual-head
You can use the
right} option to specify the relationship of the second screen to the first.
For more than two heads, or multiple cards, you can use the following approach to generate an appropriate X config. First, list adapters to see what adapters are available:
# aticonfig --list-adapters
Now, a variant of one of the following commands to generate an X configuration for your needs:
# aticonfig --initial --heads=4 --adapter=1 # aticonfig --adapter=0,2 --initial # aticonfig --adapter=all --initial # aticonfig --xinerama=on
One you have your displays enabled so that your mouse pointer can move to all displays, you still may not be able to drag windows to certain monitors. In this situation, each monitor is probably configured as a separate X screen, and you'll need to use the Catalyst Control Center
amdcccle GUI configuration tool to tie them together. The Catalyst Control Center is installed when the
qt4 USE variable is enabled.
Open up a graphical terminal, and become root by typing
su - -- your user will need to be in the
wheel group to do this:
$ su - Password: ******* # source /etc/profile # amdcccle
Navigate to Display Manager, and choose the option
Multi-display desktop with display(s) X for each display. Then, drag and drop the blue displays to arrange them to match how they are arranged in front of you. Click
OK. The Catalyst Control Center will tell you that you will need to restart your system for the changes to take effect. Simply log out if you are running
xdm, or end your X session, and start it up again. You should now have a fully-functioning multi-head display.
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:
# aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0
You will need to restart your X session for the changes to take effect. If you are using a display manager, logging out and back in again should cause the new settings to be visible.
Compton with backend glx does not work well with ati-drivers
Try running compton with the following switches:
# compton --backend glx --vsync none --paint-on-overlay
