If I understand correctly you are having login issues on the workstation, not the remote systems.
You didn't say if you logged in via ssh or vt1. I wonder at what level the issue is: kernel display driver,
x-server, display manager, or pam. If ALT+F7/CTRL+ALT+F7 is blank it would suggest that gdm didn't
start or crashed quickly.

It would be really helpful to be able to log into them XDMCP. Note: this isn't a remote screen, it's actually connecting to new sessions via the XDMCP protocol. RDP is another possibility but it would be an application, not a full session.

I would also try updating to 18.10 but it looks like do-release-update doesn't want to change from LTS to semi-annual and update-manager requires a desktop. I could dig into conf files but at this point I'm losing patience.
