When I turn on my laptop from sleep, I have to input my password twice. Once there is a white rectangular window (reminds me of gnome) and then lighdm unlock screen. When I dissable "Ask for password after sleep", I still get the white window.

System: Ubuntu 16.04 with Unity

//EDIT:

Unlock screen asks twice only if AC is not plugged in.

Thank you

After some research I found a solution.

Package gnome-screensaver had to be removed, as it was installed as dependency and caused above bug.

To remove it, simply type in terminal:

sudo apt remove gnome-screensaver

Ran into a similar issue since yesterday after a bunch of updates, Ubuntu 16.04 LTS, with the AC plugged in.

Removing the package gnome-screensaver helped, but I had to reboot to make it work. Before the reboot, I didn't get the grey password popup any more after resuming from stand-by, but also not the regular unity login either, so I couldn't log back in at all (also couldn't go to shell via CTRL+ALT+F1).

After a hard (power off) reboot, everything seems to be working again.

Hope this helps!
