I think I have the same bug. I use Xubuntu 19.10.
When the screen locks, mouse and keyboard events will lake me to the unlock screen. Password is accepted, but screen never shows the desktop. I can log out and log in again to restore the desktop, but of course this closes all applications. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1825785 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 Status in lightdm package in openSUSE: New 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.
