Noticed previously that the status of my working Gnome (Ubuntu 16.04) desktop's GDM3 service is a bit different than the bugged machine. Attached is a series of systemctl status updates before and after stopping and starting the GDM3 service. Note that I did not run any other systemctl command against GDM3 since the last reboot for this output.
There seems to be differences in opening and closing sessions involving PAM. My working system starts a PAM session and leaves it running. In the non-working system it appears that GDM ends the session shortly after opening it, and some child processes have died right away as well. ** Attachment added: "systemctl_status_gdm3_001.txt" https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1777378/+attachment/5153858/+files/systemctl_status_gdm3_001.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1777378 Title: GDM no longer presents GUI login Ubuntu 18.04 Status in gdm3 package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete Bug description: Background: Did a clean install of Ubuntu 18.04, standard Gnome desktop.
