I am running Fedora FC38. I have 2 monitors connected to a RX 580 Pro. When I boot up the monitors will only duplicate. Before I upgraded to FC38, I could extend the monitors. After much searching it appears that the proper driver is not getting loaded. The output of different commands indicates that the driver is "N/A". I have tried to reinstall the drivers but nothing happens. I know the hardware is good because I have a Fedora 38 live dvd. I booted it and the displays work as expected - extended. How do I force load the proper drivers?
I am not sure how I fixed this. I added a modprobe authorizing the smdgpu driver. I added a modprobe file to blacklist radeon. In the bios, I disabled Thunderbolt.
I don't know which one or maybe all fixed my problem.
