Introduction

This document details building the open-source "radeonhd" driver. This shouldn't be necessary unless you're having problems with the open-source "ati/radeon" driver that comes pre-installed with Ubuntu. If you were looking for instructions on installing the proprietary ATI Catalyst/fglrx Linux drivers, see: http://wiki.cchtml.com/index.php/Ubuntu_Jaunty_Installation_Guide The radeonhd driver, or xf86-video-radeonhd is an X.org video driver for R500 and newer ATI graphics devices. It is being developed by Novell/SuSE for AMD, with the free documentation provided by AMD. At the time of this writing, the radeonhd driver offers accelerated 2D/3D/Xv for R5x0 (X1k cards & 690G IGP) and accelerated 2D/Xv support for R6x0/R7x0 (Radeon HD series). 3D acceleration for RadeonHD cards is under development at the time of this writing. You can keep track of when acceleration and other features are supported here: http://www.x.org/wiki/RadeonFeature

Preparation

Previous or current installations of ATI's proprietary Catalyst/fglrx drivers are known to interfere with the installation of the open-source drivers. If you've installed the proprietary drivers through Ubuntu:

sudo apt-get purge xorg-driver-fglrx fglrx-amdcccle fglrx-kernel-source xorg-driver-fglrx-dev

If you've installed proprietary drivers downloaded from ATI/AMD's website:

sudo sh /usr/share/ati/fglrx-uninstall.sh

To make sure you have the correct version of libGL:

sudo apt-get --reinstall install libgl1-mesa-glx

Prerequisite Packages

Using the following commands will get all the packages you'll need:

Ubuntu 9.04/Jaunty or 8.10/Intrepid

sudo apt-get install x11proto* xutils-dev autoconf libltdl7-dev libpciaccess-dev libdrm-dev git-core gawk xorg-dev libgl1-mesa-dev pciutils-dev

Getting DRM Kernel Modules

Notes: The commands in this section are unnecessary for people running Ubuntu 9.04 Jaunty or Radeon X1k/690G users. These commands assume you're running the kernel provided by Ubuntu.

cd ~/
git clone git://anongit.freedesktop.org/mesa/drm
cd drm
git checkout -b r6xx-r7xx-support origin/r6xx-r7xx-support
./autogen.sh
cd linux-core
make radeon.o drm.o
sudo cp drm.ko /lib/modules/`uname -r`/kernel/drivers/gpu/drm/
sudo cp radeon.ko /lib/modules/`uname -r`/kernel/drivers/gpu/drm/radeon/

Building radeonhd

Note: Make sure you're connected to the internet when running the git command

cd ~/
git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-radeonhd
cd xf86-video-radeonhd
./autogen.sh --prefix=/usr
make
sudo make install

Configuration

Configuring xorg.conf for radeonhd

Open your xorg.conf for editing:

gksudo gedit /etc/X11/xorg.conf

Now change/add the Driver line in the Device section. You can also add the option for Direct Rendering here.

Section "Device"
	...	
	Driver   "radeonhd"
	Option   "DRI"
        Option   "AccelMethod"  "EXA"
EndSection

Also, add this section to give non-root applications access to DRI services

Section "DRI"
	Mode         0666
EndSection

Save the file and quit. The changes will take place the next time you restart X.

Configuring Compiz

Note: Compiz requires 3D acceleration, so it will only work for Radeon X1k and 690G-based graphics units at the time of this writing:

gksudo gedit /usr/bin/compiz

Now find the WHITELIST= line and add radeonhd so it looks like:

WHITELIST="nvidia intel ati radeon i810 fglrx radeonhd"

Diagnostic Commands

Radeon X1k and RS6x0

glxinfo | grep "renderer string"

This command should return a line that looks like "OpenGL renderer string: Mesa DRI R300..." If it returns "software rasterizing" then it would be a good idea to have an expert look through your /var/log/Xorg.0.log file to see what's wrong.

RadeonHD 2k-4k

cat /var/log/Xorg.0.log | grep "Direct rendering enabled"

This command should return "(II) RADEONHD(0): Direct rendering enabled" if the DRM module loaded properly.

Updating The Driver/Source

Check the following link to see if the driver has been updated since you've installed it: http://cgit.freedesktop.org/xorg/driver/xf86-video-radeonhd/ If so, you can pull the updates and recompile the driver to update it:

cd ~/xf86-video-radeonhd
git pull
./autogen.sh --prefix=/usr
make
sudo make install

Pre-built .deb packages

Unofficial test packages updated from git can also be found at https://launchpad.net/~tormodvolden/+archive
