After updating my Centos 8 workstation, I got a black screen after booting to Centos, I suspected some problem with the graphics card, since I could ssh to my machine and everything else would work fine.

I installed the latest drivers from amd following the steps recommended by AMD to install the drivers. I've also checked that my card is in the "Product Family Compatibility"section.

I get a warning when installing, which makes me think if the latest drivers are not compatible with the kernel I'm running:

WARNING: amdgpu dkms failed for running kernel

Is there anything I can do, except running the version before my update?

I fixed my Problem by

  1. uninstalling amdgpu driver by following amd recommendation on how to uninstall amd drivers: running sudo amdgpu-uninstall in terminal emulator.
  2. Updating to kernel version 4.18.0-147.5.1.el18_1.x86_64
  3. Installing amdgpu-pro-versionlist-19.50-1011208.el8.x86_64
  4. Rebooting
