I finally did it and got an used RX 6950 XT to replace my GTX 1080 Ti. I’ve been using this card ever since I moved to Linux and now I’m wondering what exactly I have to do. On Windows it’s mostly run DDU and install the new AMD drivers, everything else will probably work the same with Afterburner etc.
However, on Linux the only things I know are uninstalling the Nvidia drivers, removing GWE since that obviously won’t work and installing Mesa.
What other steps do people recommend? I’m hyped to finally get properly working GPU acceleration in Firefox and other things like Steam, but is there anything I have to do to get that running? Also what tools are currently a must with an AMD card for some undervolting / overclocking and other functionality y’all can recommend?
Just to clarify, I use Pop!_OS and not Fedora Ublue. I looked at their Wiki because they are the only ones who had documentation on how they made hw accel work with Flatpak and Nvidia specifically. More exaclty I was led there by this Reddit post.
AFAIK it should work fine with AMD since Firefox can use the VA-API FFmpeg Flatpak to provide hw accel which should work fine with AMD GPUs. This does however not support Nvidia GPUs, which is why you have to expose the driver in the sandbox and force Firefox to try to use it etc.
