History

• I have Ubuntu. Because of its extraordinarily slow speed (especially after upgrading to 16.04 from 14.04, almost as slow as Windows), I installed lubuntu-desktop and now use Lubuntu. The change has greatly speeded my computer.


• I am able to choose whether to boot into Ubuntu or Lubuntu each time I log in.


• After this change, in Lubuntu, the automatic suspend would not work because it asked for the password. I fixed this using the solution to Authentication required before suspend.

Problem

When I resume from automatic suspend, I am greeted with an unusual login screen, which has only three elements:

• The day and time


• The title "Light Display Manager"


• A prompt to enter a password without a user being displayed

When I enter my password, the prompt responds with, "Incorrect password". I have, of course, tried multiple times and typed my password carefully.

I cannot proceed from that screen, and even Ctrl+Alt+Delete doesn't work. I have to use REISUB. EDIT: I can also sign into a console (Ctrl+Alt+F1) and sudo reboot.

Extra notes

If I suspend manually, or if I use Ubuntu, the computer resumes properly with the correct login screen, accepting my password and allowing me to continue. Only the automatic suspend from Lubuntu gives this problem.

Question

How do I get the computer to resume correctly from automatic suspend when using Lubuntu?

16.04 lubuntu suspend password

  The lubuntu-desktop metapackage installs the xfce4-power-manager so maybe the problem is that both xfce4-power-manager and gnome-power-manager are active. Try to disable suspend from the gnome-power-manager and enable it at xfce4-power-manager.

This solved my problem

sudo apt remove gnome-screensaver

There is a conflict between screensavers as LightDM starts up gnome-screensaver when the device goes into suspend at the lock/login screen.

For a quick temporary fix:

• Login to a terminal, use CTRL+ALT+F1 or ...+F2 etc.




• Kill light-locker as admin: sudo pkill light-locker
