ATI RS690m X1200 proprietary driver installation

I've installed Ubuntu 11.10 on my emachine e625 AMD64 (TF-20) with an ATI RS690m X1200 graphics card but I didn't have 3D acceleration. The open-source driver works, except for any video effects or acceleration… I've downloaded the driver from ATI and followed the installation instructions and here is the result:

Error: ./default_policy.sh does not support version
default:v2:x86_64:lib32::none:3.0.0-17-generic; make sure that the version is being
correctly set by --iscurrentdistro

What did I do wrong?

Solution 1:

The file that you downloaded is ati-driver-installer-9-3-x86.x86_64.run. It is an executable file.

• Right click on the file, Properties, Permissions tab, check "Allow to run this file as a program".
• Then in a terminal, move to your download folder, probably by typing cd ~/Downloads/.
• In the same terminal window, launch sudo ./ati-driver-installer-9-3-x86.x86_64.run.
• Follow the installation wizard.
