These instructions will hopefully help those who are testing the Beta over the next few days to get full hardware acceleration from their graphics cards.
These instructions are based off Ubuntu’s guide here: https://help.ubuntu.com/community/RadeonHD and I can only comment on my set up, I cannot guarantee that they will work for anyone else.
Firstly make sure that you graphics card is not already working properly, in a terminal type:
glxinfo | grep “renderer string”
If you see “software rasterizing” as the output then the drivers are NOT working right, if you see something else then they most likely are.
First prepare your system for installing the new drivers, do this by removing the old drivers and making sure you have the right libraries installed:
sudo sh /usr/share/ati/fglrx-uninstall.sh
If the file cannot be found then it is good, just means the driver was never installed in the first place.
sudo apt-get purge xorg-driver-fglrx fglrx-amdcccle fglrx-kernel-source xorg-driver-fglrx-dev
Package not found errors here are also really good.
sudo apt-get --reinstall install libgl1-mesa-glx xserver-xorg-core
Make sure that the reinstall of these two packages completes properly. (Note: the reinstall flag has two – before it not one, some web browsers render the double dash as a single long dash).
Next you need to install a new Kernel, Ubuntu 10.04 will ship with 2.6.32 but at a minimum (at the moment) you need 2.6.33, this is simple to do though:
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33/linux-headers-2.6.33-020633-generic_2.6.33-020633_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33/linux-headers-2.6.33-020633_2.6.33-020633_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33/linux-image-2.6.33-020633-generic_2.6.33-020633_amd64.deb
sudo dpkg -i linux*
Now reboot and make sure that you boot into the new kernel and not the old one.
Add the following address to your systems software sources:
Reload the sources list when prompted, then go to update manager, check for new updates, install all the new updates that are listed. Once installed reboot your system.
Now try “glxinfo | grep “renderer string” again and hopefully it will no longer display software raster and instead something a lot more promising.
