Title:
lightdm: screen does not wake up on mouse/keyboard events
Status in lightdm package in Ubuntu:
Confirmed
Status in xfce package in Ubuntu:
Confirmed
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://bugs.archlinux.org/task/59750
* 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{,-common} 1.20.0-9 makes the
screen behave as expected.
