I have a two-monitors configuration.

Sometimes after a long period the passord dialog on lock screen doesn't work. Input control doesn't appear. Is may happen in one or both monitor dialogs.

What can I do?

  • but you see the window? I mean your username is displayed but no input box, correct?

This is a known "bug"

you can do the following workaround :

ctrl + Alt +F1 to switch to VT1

enter your username and password and run

unity --replace

switch back using:

ctrl + Alt +F7

Sometimes the top bar disappeared which can be resolved using :

compiz --replace

Also a simple unity will restart your unity...

For me this works, but I heard from others, that they couldn't see the top bar using compiz --replace

    compiz --replace worked for me in a console back in graphic mode. Thank you. Oct 13, 2014 at 15:22
  • These variants didn't work for me. At least from VT1 I can issue a "reboot" command and get a relatively clean restart.
