This tutorial will help you to install ATI drivers on Debian 5(lenny)
First you need to download ATI drivers from here and run the downloaded script as root
#sh ati-driver-installer-9-10-x86.x86_64.run
Follow the on screen instructions
Troubleshooting
If you got an error during the installation try the following:
#apt-get install build-essential module-assistant fglrx-driver fglrx-kernel-src
#m-a update
#m-a prepare
#m-a a-i fglrx
and then try to install the package again “sh ati-driver-installer-9-10-x86.x86_64.run”
It should be ok after this.
This worked perfectly! I ran the troubleshooting steps first and then I ran the ATI installer (ati-driver-installer-9-3-x86.x86_64.run).
Thanks for the post!
