Comment 48 for bug 1311403

I have the exact same problem happening in different situation (all related to suspend):
- When I lock screen, later some time without activity it get suspended automatically.
- When suspended by closing lid.
- When suspended by clicking on suspend.

So it appears to be resume from suspension general issue. I'm on Gnome with latest updates. It is very annoying.

Mouse movement works, but no response from mouse buttons being pressed neither keyboard keys. After some time it works.

My workaround (doesn't work all the time) is to scroll down the clock, then scroll up from clock to input password again (it usually works, but not always).

Same behavior when I'm also using two monitors.
