Same problem here. My complete shell is stuck just because of one, un-
closeable modal dialog whose cancel button isn't working.

Attached encrypted USB drive gets stuck in password prompt
Status in gnome-shell package in Ubuntu:
I used the standard tools in Ubuntu 16 to format and encrypt a large
USB hard drive for storing secure backups to. I then used that drive
with the standard "Backups" tool to capture periodic backups.
My hard drive recently died, forcing me to re-install Ubuntu 16. The
re-install went well, but when I tried to attach the drive to restore
my personal files, a modal appeared, prompting me to enter my
So I did. And then it prompted me again. I thought I'd mistyped my
password, so I re-entered it, making sure my caplocks or numlock key
weren't on, but again, it prompted me. After each prompt, the full-
screen modal darkened the background until after a dozen attempts, my
background was almost completely black. I suspect what's going on is
something's trying to access the encrypted disk while I'm typing in
the password, and each access is triggering another prompt,
effectively locking me out of the system because it's impossible for
me to enter a nearly infinite series of prompts.
This bug is a huge problem for two reasons:
1. it locks you out of your computer
2. it prevents you from accessing secure storage and restoring your system
I managed to partially workaround #1 by switching to a terminal and
running `export DISPLAY=:0; gnome-shell --replace`. That caused Gnome
to reload, which minimized the modal program, allowing me to kill it
in the app thumbnail view.
However, that's a huge hassle, and I'm still unable to access any data
on encrypted USB drives, even when I enter the password correctly.
I don't know exactly what component to file this bug under, so I chose
"gnome-shell". Please re-tag it if this is incorrect.
