Public bug reported:

Binary package hint: gnome-control-center

Run gnome-display-properties. Pick a different resolution. Click
"apply".

What I expected: I expected a confirmation dialog with a countdown to
appear, saying that I should click "OK" if my monitor was displaying the
resolution. (More accurately, since the resolution I picked was out of
range, I expected that my monitor would snap back to the old resolution
eventually.)

What happened: My monitor proceeded to display the "Invalid Resolution"
message for quite some time. I did a CTRL-ALT-Backspace, and tried to
log back in, to discover that the invalid resolution was now part of my
user profile, making my account nigh-unusable.

Compounding this problem was the fact that "failsafe" mode doesn't reset
resolution changes; I ended up creating another user account from the
xterm-only account (since CTRL-ALT-n doesn't switch to a plain tty any
more), logging in there, and trying to find any reference to ways to
change the mysterious setting which wasn't in .gnome or .gconf and
wasn't affected by logging in as failsafe, but *was* affected by logging
in as "terminal only".

(For some reason, I found a forum post rather than
https://wiki.ubuntu.com/X/Config/Resolution, but eventually I deleted
.config/monitors.xml. In any case, this is hardly bulletproof, and I'll
file a bug on whatever makes failsafe configurations as soon as I find
out what component it is. Aren't we supposed to have "bullet-proof X"?)

I don't think this is a dupe of bug 197673, since that was about randr
changes, while this is just about screen-resolution changes. If it *is*
a dupe, please just reopen that one.
