I have a Dell Precision T5500 with an NVIDIA G98 [Quadro NVS 420] running Ubuntu 18.04.
I ran into the login loop problem after updating from Java JDK 8 to JDK 11 and rebooting.
I tried workarounds like
- ``` dpkg-reconfigure lightDM ```
- ``` chown user:user .Xauthority ```
- ``` mv .Xauthority .Xauthority.bak ```
etc. I eventually purged NVIDIA drivers using
sudo apt-get purge nvidia*
and tried rebooting and logging in, unsuccessfully, before attempting to reinstall drivers.
I tried multiple combinations of purging drivers and reinstalling using
sudo ubuntu-drivers autoinstall
sudo apt install nvidia-340
and also tried using apt-get to fix missing and broken packages.
I ensured that there is no ‘nomodeset’ kernel parameter, and tried running
grep modeset /etc/modprobe.d/* /lib/modprobe.d/*
which returned no result even when using sudo.
I’ve attached a log file created after rebooting the computer and trying to log in once.
