Package: lightdm
Version: 1.18.3-3
Severity: important

Dear Maintainer,

This bug is similar but different from other reports.
On startup lightdm work always for me.

When the screen locked, regardless of the cause,
and I move the mouse to resume,
randomly unlock screen doesn't appear.

I see the mouse pointer as a black X
and I can't do anything.

I change tty with CTRL+ALT+1
I enter with my credentials
I can write: "sudo systemctl restart lighdm"
and lightdm unlock screen appears
