First a followup on a prior question - I realized what I was actually
looking for was XDMCP - I have a bunch of headless systems, far too many to
connect to monitors even with KVM switches. 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 tried a few tweaks but didn't get anywhere. I rebooted a number of times
without any problems.

Skip forward to this morning. I've been logged in for awhile but wanted to
logout/login since Chrome was consuming all 48 GB of RAM again. I do this
every so often - better than having to a power hit. Only problem was I
never got the login page after logging out.

I rebooted. No login page. I get the usual page to enter the hard disk
encryption key but not GDM3.

I revert /etc/gdm3/custom.conf. No joy.

I *purge* gdm3 and reinstall it. Verify that it reinstalled custom.conf. No
joy.

This is more than a little annoying, even alarming. I haven't had problems
upgrading releases for the last few years but had to reinstall Ubuntu on a
few systems since the upgrade failed. It often failed where X came up but I
couldn't log in, or I could log in but never saw a desktop.

Now this happened and I don't know if it's because a routine update broke
something. That's not acceptable - I can't risk having to take hours out of
my workday in order to reinstall my OS.

For now I'm going to try dpkg-reconfigure one last time and then try
installing KDE. 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.
