I'm on Kubuntu 20.04 LTS. I use my laptop connected to an external monitor via HDMI (with dongle type-c to HDMI).
After the laptop goes to sleep because of inactivity and I "wake it up", suddenly there is a black screen with just the KDE screen where I have to put the password.
It takes a long time before I can manage to write the password because the system seems to not get input nor from the track-pad, nor from the keyboard, neither from a cabled mouse.
Then, when I manage to log in, basic i3 "starting screen", even though I have a wallpaper and bumblebee-status, plus the keyboard doesn't work, just the trackpad and mouse. I litteraly cannot do anything from there.

Do you have any ideas on how to solve this?
