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

Creating a Friendly Funtoo CultureThis news item details some recent steps that have been taken to help ensure that Funtoo is a friendly and welcoming place for our users.
CPU FLAGS X86CPU_FLAGS_X86 are being introduced to group together USE flags managing CPU instruction sets.
AMD Catalyst Video Drivers
These drivers are not being regularly maintained by AMD, resulting in a sub-optimal and unreliable experience for many users. Symptoms generally involve X not starting at all, things like gnome-shell crashing on startup, etc. If you have problems with these drivers, consider using the free Radeon Video Drivers, which are actually quite good and hassle-free.
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
The release of the 14.9-r1 driver ebuild eliminates the need to mask
ati-drivers-14.9-r1 has been added to the Funtoo Portage tree which contains a special Ubuntu-only release of the drivers that are compatible with x11-base/xorg-server (package not on wiki - please add) version 1.16. If you are using the "stock" drivers, then typically, you would need to mask
xorg-server as follows. This is not necessary with 14.9-r1:
Add the following to
If X is already installed, force it to downgrade by typing:
# emerge -auDN world
A few packages will downgrade, and you'll be ready to go.
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
To emerge the drivers, run the following command:
# emerge -av --changed-use --deep @world
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
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 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:
# compton --backend glx --vsync none --paint-on-overlay
