For years I have only used nvidia cards. Yesterday I bought RX 6600 - how do I install the graphics card driver correctly in OpenSUSE Leap 15.6? How do I check if it is installed correctly? I have found several methods - I do not know which one is correct. Is it possible to check the card temperature in OpenSUSE?
Unless you need some of the ROCm functionality, you don’t need to install anything.
The AMD Graphics Drivers are part of the Linux Kernel.

I just went through a bit of work to get an AMD RX570 installed in place of a GTX1050.
The best advice I can offer is if you downloaded and installed the Nvidia drivers using the script that Nvidia provides on their website use that same script with the -uninstall option. It will remove the Nvidia driver and try to set things back to where the AMD card will be recognized at least well enough to get you a GUI Display manager to work with.
I had heard that linix had native baked in AMD drivers that “should just work”. I think that may be true if you start your installation with an AMD card but it is not true if you had an Nvidia card installed during the initial installation and then later updated drivers for that Nvidia card off of Nvidia’s website.
I know how to maneuver in console mode and YAST offers a Ncurses version that works pretty well in console mode as long as you remember to use the tab, space, and enter keys instead of wishing the mouse worked. Yet nothing I did in removing Nvida references and drivers and adding AMD drivers made any difference until I had ran the Nvidia shell script with the -uninstall option.
I had taken so much of the old Nvidia driver away in YAST that that the Nvidia shell script refused to run when I first tried to run it to use the uninstall option. I ended up running it like I wanted to install, it did complain about not finding a compatible Nvidia card, yet it eventually completed. After that I was able to run the script a second time using the -uninstall option.
Bootup later gave me a GUI to work with though it seemed to be slow and glxgears did not run. I downloaded the latest radeon driver from AMD and ran its install script and then glxgears showed as working.
Pass glmark2
Pass eglinfo -B
Pass vainfo
Pass dmesg | grep 'amd'
Pass # /sbin/lspci -nnk | grep -EA3 "VGA|Display|3D"
I removed everything that had nVidia in the name. Which also removed the graphical environment. But later I installed plasma-KDE in yast. The system returned. Drivers according to the scheme on this page:
