Created an account just to confirm I too am hit with this bug. Started as 19.04 running on Ryzen 2700X, 32G, RTX2060 with nVidia 430 drivers.
After successfully upgrading from 19.04 to 19.10, or so I thought, I was met with the login screen upon system reboot. This was very strange as I had auto-login set to true with 19.04 so I should *not* be seeing this login screen. My linux-fu is weak as I'm currently transitioning from OS X to Linux and was completely lost on how to continue. The solution was to go scorched earth and do a clean install of 19.10. My /home directory is on a separate drive so I was confident things would work out ok. The clean install went well but at this point I was still unaware that the issue was related to the auto-login (and perhaps nvidia 435 combo). So after modding my fstab and rebooting I was confronted again with the login screen and not being able to login (ie, no matter how many times I typed my password the login screen would ignore me). After some Googling I discovered this page you are reading now. I did another clean install but this time I mv'd .config and .local in my /home directory to borked.config and borked.local (as mentioned, my linux-fu is weak but I assumed that my previous auto-login setting is stored in a pref file *somewhere* in either of those directories). After updating fstab I then toggled the auto-login a few times to ensure the prefs would show it clearly in the OFF position. Then I rebooted. SUCCESS. The login screen appeared but this time I *was* able to login — I spent another hour moving files from my *borks* back to .config and .local and I'm mostly back to normal. As mentioned by anidotnet above, this is my second update (18.04 > 18.10 && 19.04 > 19.10) and both were extremely unpleasant with this latest update taking the cake. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1845801 Title: [nvidia] Automatic login fails and then all subsequent logins fail.

After boot, I'm shown the GDM login screen (which I shouldn't; I have auto login enabled), and logging in just takes me back to the same user selection screen even though the password is correct. If I switch to a TTY and run `sudo pkill gnome-session-binary`, logging in through GDM starts working again. I should add that the do-release-upgrade was rocky; I did it in a terminal from within gnome, went away for a while, and when I returned, I just saw an Ubuntu 19.10 in a TTY. I was able to do `sudo dpkg --configure -a` and complete the upgrade, but I don't know if something's still messed up due to that.
