I've made the mistake of installing the ATI proprietary driver by command line.
Steps i took:
- Downloaded linux drivers
- Opened the terminal
- sh amd..driver.run
- Followed the steps
- Rebooted
This has caused my screen to not even load after a fresh install of 11.10 Is there a way to remove of disable these proprietary drivers by command line?
Enter root shell
Go to the location where you downloaded the installer then:
./ati* --uninstall
Reboot:)
But, you can also get the drivers working by following the steps above, then follow steps 1 to 3 again and replace step 4 with:
./ati* --install
.Then type:
aticonfig --initial
Then reboot.
This is how I got the latest drivers from ati working.
Check wiki.
