X11 failsafe was not very useful

[Seth Arnold]

Hello, after upgrading from 16.04 LTS to 18.04 LTS I had a non-working X11 configuration.

The first dialog box said:

The
system
is
running
in low-
graphics
mode

Your
screen,
graphics
card, and
input
device
settings
could not
be
detected
correctly.
You will
need to
configure
these
yourself.
[ OK ]

The next dialog box had four options:

[ ] Try running with default graphical mode
[ ] Reconfigure graphics
[ ] Troubleshoot the error
[ ] Exit to console login
[ Cancel ] [ OK ]

Try running with default graphical mode --> didn't work, returned

Reconfigure graphics --> a new dialog box:

How would you like to reconfigure your display?
[ ] Use default (generic) configuration
[ ] Use your backed-up configuration
[ Cancel ] [ OK ] (probably OK, my photo cut it off)

Neither option worked.

Troubleshoot the error --> a new dialog box:

What information would you like to review?
[ ] Review the xserver log file
[ ] Review the startup errors
[ ] Edit configuration file

Review the xserver log file --> A new dialog box, with the log file.
I can't recall what the "startup errors" button did.
The "Edit configuration file" button didn't do anything useful.

There was a lot of interaction options in this whole experience but the only ones that actually worked were (a) show the log file (which wasn't actually useful, but I was grateful for it) (b) exit to console login. That actually worked pretty well.

I'm sorry I waited too long to report the bug, now my memory is pretty fuzzy. I just remember that not enough of this system worked to justify keeping it. Maybe that's due to local errors, the upgrade didn't go well, but that's precisely when such an interface will be needed most.

Thanks
