I have recently installed Kubuntu 18.04 on a Dell XPS 13 9370. I cannot switch from the GUI to any virtual console using Ctrl+Alt+Fx for any x=1,2,... (or any key combination I can discover). I have never had a Linux system with this property. I would be grateful for any information on how to fix this.

If you use a laptop, Fn-lock is one possibility. Try Ctrl+Alt+Fn+F3.
If that works and you want to turn off Fn-lock, look for the lock icon in the upper row of the keyboard and press Fn+that key. If you can't find one, try Fn+Esc.
First, edit /etc/systemd/logind.conf
uncommenting the first two lines:
NAutoVTs=6
ReserveVT=6
then execute
sudo chvt <vt_number>
from any terminal emulator.
Personally I didn't manage to make hotkeys work in the GUI, but they work while using other virtual terminals.
