Doesn't unlock when coming back from the greeter

@seb128 can you reproduce this bug all time? Seems fine here.

yes, but only by picked another user in the indicator-session from my session

I was going to make a new report, but I am almost positive that this is the same issue but with a different trigger.

My computer is only a single user, but sometimes when I unlock the screen from being inactive, a new lock screen pops up seconds after unlocking.

Procedure:
Since I upgraded to the developer version I have had this issue several times. I leave the computer unattended overnight. The power settings are not configured to allow the computer to go to sleep. When I come back, I log into the lock screen and it unlocks. I can interact with the desktop for a few seconds before the screen turns black for a few second and a lock screen pops up again. Shorter durations of inactivity-triggered "locked" time do not seem to replicate this behavior.

I do not really know where to look to gather more information.

I've got one user.
If I lock screen by Ctrl+Alt+L and then login back, everything is OK.
But if some time took after locking, then I shold login twice.

I have two users on my laptop, in an attempt to have different sessions for different work.

Switching from one user to another takes me to the greeter to enter my password, but when the new session starts, it immediately takes me to the new lockscreen and requests the password again. This is very annoying.

Same for me on a single user system.
Sometimes I have to unlock two times the lockscreen

the update didn't fix the issue, reopening

"That fix didn't work...

Doing:
- log as your user
- use the indicator-session to start a guest session
- close that session (which brings you back to unity-greeter)
- type your password

That sends you back to a lockeed session :/ (that's using today's trusty landing, the new code is running since e.g "esc" is clearing the password entry)"

Actually I cannot reproduce the issue using the above steps.

Do you have a locally hacked gnome-screensaver version again? ;-) (you tried with a guest session right?) Could you try with the archive version?

I still get it to lock after unlocking after a suspend :/

The fix don't work for me too, I have a single account system with default configuration

Seb, yeah pretty sure it's a normal gnome-screensaver. Maybe just with different settings?
