Bug Description
Description: When session is locked either using dm-tool or light-locker, lightdm greeter is functional (you can type your password and press Enter to unlock the session) but screen is not turned on, and remains turned off even when you move the mouse or press any key.
Although, it doesn't occur when you close your session instead locking it.
Additional info:
* xorg: 1:7.7+19ubuntu12
* lightdm 1.28.0-0ubuntu1
* xfce4-session: 4.12.1-6ubuntu1
From lsb_release:
Description: Ubuntu 19.04
Release: 19.04
* Reproducible on other distributions as well. See here: https:/
* Reproducible on both Intel UHD Graphics and AMDGPU Graphics.
Steps to reproduce:
* Lock the running session using lightdm
* Screen is turned off, but it won't turn back on when you move the mouse or use the keyboard
* You can type the password and press Enter to unlock the session. It the password is correct, the screen will finally turn on and you will be at your desktop.
Note: switching out and then switching back to tty7 restores visibility of the lock screen.
On Arch Linux, downgrading to xorg-server{
