Do you have ssh or local console login working? If so, then it is purely a GUI issue. If not, it is something else.


If you have a login, try deleting "~/.cache/compizconfig-1/".

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.
