Running journalctl -p3 -xb it turns out that every time I log in I have a coredump because Xorg crashes? It restarts automatically so I would never have noticed without running the command.
I can’t seem to get the EOS log tool to work; I know I can pipe it directly but memory like a goldfish, someone will have to tell me exactly how.
Still indicates the drivers are up and running, it’s “just” that Xorg crashes and restarts during login, and then it works.
I suspect a “Proper” solution to run on kernel 5.10 is to run on free drivers or wait until 5.11 which reportedly has better compatibility with NVIDIA.
