I picked up an AMD 9060 XT the other week and tested it out by dual-booting Bazzite. Helldivers 2, TRYP FPV Drone Racing, Mud Runner all ran as expected, it was wicked.
“Nice,” I thought, “This works great, time to boot back into Fedora.”
And… not so nice? Apparently Fedora doesn’t have hardware acceleration when using AMD GPUs and a bunch of the apps I normally use are whinging about it. It was fine with the older NVIDIA card I had been using but I wasn’t getting the performance benefits of gamescope.
Dabbled in the dark arts of trying to swap mesa drivers to the freeworld one and ended up nuking my login screen so probably going to have to roll back. I thought Bazzite was based on Silver Blue so kinda confused, I guess they’ve done some AMD-friendly tweaks?
Edit: Thanks for all the help everyone. I was on Fedora 42 and after installing updates today it started working again. I really wish I new what specifically was causing the issue.
Nope, KDE doesn’t deal with anything at the driver level. Pretty sure it was a combo of removing the Nvidia packages, and then you probably got a kernel update which forced the kernel modules to rebuild and it detected and included your new AMD hardware.
This is normally done automatically, HOWEVER, if you have something like the Nvidia stack of drivers on your system, you can get weird behavior because the package maintainers pull all kinds of ugly tricks to force Nvidia bits and pieces to stick to where they need to be.
In the future, you can trigger a sort of rebuild with whatever your running kernel is like so to force changes: https://brandonrozek.com/blog/rebuildkernelakmod/
This is probably what happened when you did that update, and it refreshed the device table and made sure the AMD modules were loaded properly.
