Lubuntu rejects password when resuming from automatic suspend
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-desktopand 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?

Thelubuntu-desktopmetapackage installs thexfce4-power-managerso maybe the problem is that bothxfce4-power-managerandgnome-power-managerare active. Try to disable suspend from thegnome-power-managerand enable it at xfce4-power-manager.
