Xubuntu 18.04 installed on a new Lenovo IdeaPad 330S; system is up to date (I run Software Updater pretty much daily).
lsb_release -rd tells me:
Description: Ubuntu 18.04.3 LTS
Release: 18.04
When the screen gets locked (either when I lock it or when the system locks it after a period of inactivity), there is no way for me to log back in. No matter what I do, no "enter password" box pops up. The screen just stays black and the only thing I can do is to shut the computer down by holding down the power button.
This happens regardless of whether an external monitor is connected.
My apologies if I didn't report this correctly or left out anything important; I am just an end user and not an expert. Please let me know if I need to provide any further information.
