You were fucking with your GPU drivers, lost access to your GPU, and you have concluded from that that “regular users” (who don’t know what a driver is or does) should not use Linux?
EDIT: Stick a “normal” user on a stable distro with a clean UI like Mint or Fedora, keep in mind they probably don’t know what a terminal is and will probably never use it, and they will be fine for almost all cases.
Fedora. Silverblue if you want even more stability.
