My current Workstation is equipped with a AMD card (5000 series) where I use the non-free video drivers, from time to time there is a few days latency between the moment where the linux kernel is updated and the AMD catalyst drivers from the fusion repositories are updated to the same version of the kernel.
Over the past weeks there has been no release of the AMD drivers and the Fedora update remove the latest kernel version enabled with the AMD video drivers.
After some research, I found out that the AMD Catalyst drivers are stuck in the testing repo, but how to tell yum to retrieve the drivers from the Fusion non-free update-testing repo ?
Well you have to specify it to do so using this kind of command :
And you should have the latest AMD Catalyst driver to correspond to your Linux kernel.
This method also works with the Nvidia drivers
