Even with WaylandEnable=false gdm3 only loads sometimes
gdm3: Installed: 3.28.3-0ubuntu18.04.3
Description: Ubuntu 18.04.1 LTS Release: 18.04
I expect the greeter to load every boot.
Instead, gdm3 is not stable on my system, it will work for either one or several boots after I take corrective action, but inevitably this results in the greeter not loading. The graphics card on my Intel Core i5 system is an Nvidia GTX 970, and I manually installed nvidia-driver-415 using apt when I could not load a greeter as soon as I had installed.
Searching here and elsewhere, I have tried many things to resolve this, which I will outline below. If you know something else I can try - to get make gdm3 stable - please let me know.
Even with WaylandEnable=false uncommented in /etc/gdm3/custom.conf, I usually cannot login, instead of the greeter I would see either a black screen or graphic distortion like a black screen with some pink lines across the top, and I am only able to login setting nomodeset.
With gd3 not working, I tried lightdm, and on encountering similar issues switched back to gdm3 again:
sudo apt-get install gdm3 sudo dpkg-reconfigure gdm3
This seemed to work - kind of, for the first few days I could boot most of the time. I have quiet splash permanently removed from my boot options, and boot was sometimes hanging on Started NVIDIA Persistence Daemon.
Another time with gdm3 I saw the following output instead of the greeter.
How can I begin to resolve this issue please?
