Edit: UX Friendly - something that is intuitive and self explanatory. something you can confidently teach a person once and they'll easily be able to do it again. imagine a classroom where there's already enough things to get hung up on.
Playing Steam games frequently leads to them freezing the entire desktop. Whenever this happens, I have no UX friendly way to recover.
I've read loads of hacky ways to recover, but they all entail memorizing command line stuff, or simply haven't worked when I tried using them.
Is there a UX friendly way of approaching this? Something like Mac and Windows have had since time immemorial, where you press a few keys than select a process and kill it? Or -- if it must be done through terminal -- is there at least a command line tool that makes it easy enough I could teach a child?
