How to install AMD drivers on Fedora?

The question is in the title, " How to install AMD drivers on Fedora?" because I have no idea what to do, and I want to play games on my gnome, so ya :smiley:

Graphics Card Model: AMD Mobility Radeon HD 5470 Series

The default generic driver works well with AMD Radeon cards. It’s usually only people with Nvidia cards that need to install additional graphics drivers.

   Hi @orikindspirit.  In case of troubles with the graphics, use lspci -v to check if the card’s “Kernel driver in use” is a new driver amdgpu instead of the old one called radeon.

Okay, lets say someone (me) built a new machine using a Radeon RX 5600 XT card and loaded Fedora 32. There are two monitors connected to the Radeon card. Only one display is functioning. The lspci -v identifies the correct video card and also says the kernel module is “amdgpu”. In the Settings dialog on the Displays tab it says “Unknown Display” and on the About tab it says the Graphics is “llvmpipe (LLVM 10.0.0, 256 bits)”. Any idea’s what to do to get both monitors working and hopefully recognized? I have been wrestling with this for a week now and am about at my whits end. Been to lots of forums and asked about this but I never get any answer. It is quite frustrating.

Thanks for any help!

I have installed xorg-x11-drv-amdgpu with dnf but when I check with lspci -v I get radeon as kernel module.

For the time being I´m using nomodeset in my kernel parameters to get anything displayed. If I don’t use nomodeset my screen blanks (monitor goes to sleep) after grub.

How do I force Fedora to use amdgpu? Or, am I using the wrong driver for my card, because my card is too old?

@orikindspirit If you’re still looking for a solution. I have solved it by adding radeon.dpm=0 to the kernel command line in GRUB. It might work for you as well as we both have a card from the HD 5800 series.

To make it permanent add this parameter at the end of line kernelopts= in file /boot/grub2/grubenv
