Possibly suggesting this was memory related (not what follows is after
restart):
As I said AFTER restarting Unity I couldn't switch between windows (or
so I thought). ALT-TAB didn't pop up the switcher. I later discovered
that I the keybord shortcuts to switch seemed to work, just didn't see
"what I was doing".
Then after initiating quit in Firefox and while it was shutting down (I
guess it was slowly freeing up memory) I COULD switch WITH the graphics
and see e.g. my Firefox windows and in the end one and one of them
disappearing.
CTRL-ALT-T to start terminal didn't however work - even afterwards and
the panel was there with no info on the right or way to reboot. I had to
use the virtual console.
I would say this bug is critical for users - to possibly get locked out and -
even with a workaround most would not know - not be able to recover.
Note, if the box to input password doesn't appear because memory is low,
one possibility would be to try to allocate enough memory before locking
the screen. That could however be dangourous and change this bug into a
security one if done wrong. If memory runs out BEFORE locking, what
would happen? Would the screen then not lock?
** Summary changed:
- After going to lock screen can't login as not prompted for password - maybe
not a unity bug
+ After going to lock screen - sometimes can't log back in as not prompted for
password - maybe not a unity bug
** Changed in: unity (Ubuntu)
Status: New => Confirmed
