Firstly i am fairly new to linux. I had my system running no hitches/glitches at all - playing games no trouble through Steam.
Secondly, I attempted to update my graphics drivers recently and now I am unable to launch any game successfully.
I tried to follow this guide https://itsfoss.com/install-mesa-ubuntu/ (not bleeding edge).
After 'installing' it appeared to work however; 'glixinfo | grep Mesa' didn't show that a newer driver version (still Mesa 21.1.0)
I've tried DX11, DX12 and vulkan games, proton and linux native games.
I then attempted to purge the Kisak repo and roll back however I still can't run any games. I can get to desktop - I notice now that when i logon, the original logon wallpaper pops up for a micro second, and sometimes the icons won't be there (although that seems to be ok today so could be unrelated). I also tried to install update vulkan no luck either.
i'm on the most recent xubuntu LTS - cpu-x states Linux 5.11.0-37 generic / Ubunutu 20.04.2 LTS. Hardware is new 5000 series amd cpu and 6000 series gpu. (note that on occassion I will boot a win10togo on an external ssd).
Any assistance would be appreciated. Moving forward I will likely be trying these things on a spare usb before on the main rig.
Thanks
Russ
[edit have re-tried the process - crusader kings 3, csgo, valheim launch however sotr and everything else in my library do not]
