Fedora 34 and Radeon driver

Below is the Radeon card I have. Just a simple 2GB Gddr5 card. Fedora 34 would blank out going into Wayland. You have to add a kernel argument to grub2. “radeon.dpm=0” (dpm = dynamic power management)

VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus XTX [Radeon HD 8890M / R9 M275X/M375X

Do the following….

sudo dnf install grubby

sudo su 

grubby --info=ALL  

  **Default kernel is usually the first listed under Index0

grubby --args "radeon.dpm=0" --update-kernel /boot/vmlinuz-blahblahblah (usually first (index 0) listed kernel)

Done.  reboot.
