I recently updated to the 3.13 kernel on Fedora Core 20 and the 12.1 ATI drivers stopped working. I fixed this by downloading the 14.1 beta drivers which support that kernel. Download this here: http://support.amd.com/en-us/kb-articles/Pages/Latest-LINUX-Beta-Driver.aspx. This works perfectly for those Fedora 20 users like me who are also affected by this update. Just uninstall the old drivers using this command.
./amd-catalyst-13.12-linux-x86.x86_64.run --uninstall=force |
Then run the installer for the latest drivers downloaded from the above link. This really works.
unzip amd-catalyst-14.1-betav1.3-linux-x86.x86_64.zip chmod +x amd-driver-installer-13.35.1005-x86.x86_64.run ./amd-driver-installer-13.35.1005-x86.x86_64.run |
Then restart your system.
init 6 |
Then you will have a working accelerated Linux desktop again!
