I’ve also got the Linux Basics for Hackers book but it’s at home while I’m on vacation.
I’m just really happy rn yall :) this install took some work, SecureBoot kept getting in the way and I’m not the most savvy person so there was a lot of Googling and trial and error in the way of getting here.
Just a little last night, I installed TF2 and Caves of Qud and both ran fine OOB. I’ve got Proton on tap if I need it.
Hope you can find a solution!
