I recently upgraded to 19.10 from 19.04.
Everything appeared to work correctly, however just last night I did a
apt upgrade and some kernel updates occurred.
Now when I get to the login screen, I am unable to login. Upon entering the user password and hitting the login button, I am instantly sent back to the select user part of login.
Interestingly, if I use the GUI element to restart the computer, the warning shows that I am already logged in, even if I had not yet tried to log in after starting the computer.
Ctrl + Alt + F1-F6 freezes the screen and I am unable to do anything. Although Ctrl+Alt+Delete still works to restart the machine.
Selecting the latest kernel recovery boot from the grub menu works fine and I am immediately put into a desktop session (i3) after auto login. Once booted into recovery mode
apt upgrade and
dpkg --configure -a report 0 changes.
Any ideas on how to debug/fix this? I have a suspicion that my account is auto logging in, but then I am somehow bumped to the Ubuntu login screen where the strange state is causing issues.
I have a i5-4460 CPU, MS H81M-E34 (MS-7817) Motherboard, and a Geforce GTX 1050Ti graphics card. I am using the nvidia-driver-430 package.
