Ubuntu – This session is locked – problem

sessionsuspendunityunity-greeter

When I try to login after resuming from a suspend, I get this message with a huge lock icon.

This session is locked – you will be redirected to the unlock dialog automatically in a few seconds

Sometimes, I have to go through the procedure twice.

Why does it happen and how to solve this ?

That's light-locker's lockscreen. You can either disable light-locker by opening Light Locker Settings and turning it off, or uninstall it if you do not need it:

sudo apt-get remove light-locker light-locker-settings
