[mythtv-users] After upgrade to Ubuntu 20.04, frontend crashes X

Side note - had to rejoin with a different email address after your
listserv decided to ban my old one (which I've used on this list for over
ten years) because someone else in my mail server's IP block got onto
Spamhaus's naughty list.

In any case - one of my frontends (v31), which was running fine on Ubuntu
18.04, crashes X after the upgrade to 20.04.  The screen just goes black,
and I have to log in via the CLI on another tty if I want to do anything,
but I can't kill the pid even then, so I have to reboot if I have to use X.

It is using the same NVidia driver as it did under 18.04.

I have a couple of other machines (including my main media server, which is
a backend/frontend, and two other frontends) that I'd like to upgrade but
am waiting to get his fixed first.


This is the log dump.  I see a couple of things that *might* be an issue,
but am not sure.

Display: Found screen number 0 (HDMI-0)
