Here's the failedlogin.txt. By the way, when turning off auto login, everything works normally; I'm greeted with the login screen when the machine boots, I type in my password, and I'm logged in successfully. It's apparently just after the first failed auto-login that subsequent logins don't work.
Also, after that first failed automatic login when auto login is enabled, if I switch to a TTY, my framebuffer will sometimes be filled by a low-res gnome desktop. I assume this is related, and it makes sense that gdm would be confused if there's indeed a running gnome session for my user which doesn't work. ** Attachment added: "failedlogin.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1845801/+attachment/5293738/+files/failedlogin.txt -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1845801 Title: [nvidia] Trying to log in just takes me back to the login screen.
