KMS with a Radeon card
Note that radeon KMS is work in progress, so installing the newest possible kernel is recommended. If you use Karmic, you may want to install the Lucid kernel.
Add radeon.modeset=1 to your BootOptions to enable KMS (and DRI2) with the ati/radeon driver.
For Grub2 on Ubuntu 9.10 and later:
* sudo nano /etc/default/grub.
* Add radeon.modeset=1 to the end of the line GRUB_CMDLINE_LINUX_DEFAULT=.
* Then sudo update-grub
You can also try out KMS without rebooting, by logging out, switching to a virtual console, then
sudo stop gdm
sudo modprobe -r radeon drm
sudo modprobe radeon modeset=1
sudo start gdm
With the module loading issues (see below), this method is actually safer.
If needed, also remove the splash option from your boot options since usplash can cause some issues.
Module loading issues on ATI
If you get "RADEONDRIGetVersion failed" in Xorg.0.log it is because of a race issue. The radeon module is not initialized in time before X is starting, and X will falsely believe that there is no KMS support and do its own modesetting...
To make sure the radeon modules is initialized before gdm (and X) is starting, insert "modprobe radeon" into your /etc/init/gdm.conf just before the gdm-binary is executed:
...
initctl emit starting-dm DM=gdm
modprobe radeon
exec gdm-binary $CONFIG_FILE
end script
Missing firmware issue on ATI
If your /var/log/syslog has the line Cannot find firmware file 'radeon/R600_rlc.bin' you should download it.
sudo wget -O /var/lib/firmware/`uname -r`/radeon/R600_rlc.bin http://people.freedesktop.org/~agd5f/radeon_ucode/R600_rlc.bin
ATI KMS Results
Some benchmarking KMS/DRI2 versus non-KMS/DRI
Does DRI2 suck? No! According to the developers, DRI2 makes simple operations less efficient, like these "benchmarks" below. On the other hand, more complex operations (which will be used in a 3D-intensive application like games) should be more efficient with DRI2.
