Thank you for starting this discussion group. I would to take one step back and ask a simply question.
When you say ‘Linux’ what do you mean?
Do you mean a Linux distro like Ubuntu, Mint etc running bare metal on Intel hardware running a 64bit OS?
Or do you mean Ubuntu running on ARM architecture running 32bit OS?
Or do you mean running Ubuntu OS etc on a VMware or Virtualbox VM?
Must you have a separate GPU on your hardware to run Linux games.
Basically what do you need to run Games on Linux?
32bit or 64bit OS?
Intel/AMD or ARM architecture?
What GPU?
Ubuntu on VMware or Virtualbox?
There is no point setting up Steam if you don’t have the right hardware.
Perhaps a guide on hardware would help Linux gaming beginners.
Regards
