[Burko <rs205@xxxxxx>]

I updated my machine recently to the current Unity 7.2.4 and  this
solved this issue for some time.

BUT: Now I am experiencing it again, exactly 50 % ( that is actually 25 % of time, see below) of times I log into my maschine. My case if different, though. When my Laptop wakes up from sleep I always have to log in two times each time. Meaning I enter my passphrase, the screen unlocks, I see my screen 1-2 seconds, the screen starts flickering  and then it locks again, this time without the input field. I then close my lid so that the machine hibernates again. I wake it up again, and have again to unlock the machine  two times. This time I have in both cases an input field.
So, you could say I have to log in four times every time I want to use my machine. This is always reproducable, btw.

I did not reboot the machine so far, meaning it is up for some days now,
where in the beginning it had it prefectly working with just one needed
attempt to unlock the machine.


I attach the Auth.log entry from the last login, which seems a bit weird...

Title:
  After locking screen there is no input field to type password for
  unlock

Status in Unity:
  Fix Released
Status in Unity 7.2 series:
  In Progress
Status in unity package in Ubuntu:
  Fix Released

Bug description:
  *** IMPORTANT **

  *** The fix is not included in TRUSTY. Will be included with next SRU.
  ***

  If you can reproduce this bug please be sure to provide the following info:
  1. Do you use a multi-head setup? If yes, using just one monitor fixes the issue?
  2. Can you reproduce all the time?
  3. Do you use ldap? If yes, using gnome-screensaver fix the issue (see comment #115) can you still reproduce that?
  4. Please consider posting /var/log/auth.log (at least part of it, should not contain sensitive information)
  5. Please specify the unity version
  *** END IMPORTANT **

  Sometimes (but not always) after locking the screen there is the
  situation not having any input field where I can type the password to
  unlock the session again. The shaded gray area simply does not have
  the input field. I can't do anything, I have to switch to text console
  and stop/start lightdm service to cure the problem loosing all of my
  session :(
