Steam launches fine but launching any game fails. I mean, I click on the Start button to play an installed game, but nothing happens although my system seems to think that the game has already started though I do not see anything. I am thinking it might be a GPU driver issue. I have a GeForce GTX 1050 Ti, so I executed:
sudo mhwd -a pci nonfree 0300
but got the errors below.
error: target not found: linux511-nvidia
error: target not found: linux513-nvidia
Error: pacman failed!
Error: script failed!
