[Bug 1311316] Re: After locking screen there is no input field to type password for unlock

 

I see this on systems with LDAP, and systems without. It's just happened
on this machine, which is built from scratch about 1 week ago. It's with
a new user - so all the user config is as created by a new clean Ubuntu
system. I haven't customised PAM at all.

I see lots of failures in auth.log, but none of them are specific to
this condition. E.g:

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 :(
