I'm having this login loop issue. Fresh install of 19.10 booted the first time fine, after the first update and reboot I started getting the login loop.
I'm using an Nvidia GT-1030 and installed the proprietary drivers during the install. I removed quiet splash and added nomodeset to grub and that fixed the issue for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845801 Title: [nvidia] Automatic login fails and then all subsequent logins fail.
