One more datapoint: running unity/lightdm 18.04 on Dell XPS 13. At first my media keys didn't work, along with KB layout switch, ctrl+alt+T for terminal, etc. Installing ccsm and disabling commands plugin helped with most.
Keyboard layout switch using alt+shift/ctrl+shift works fine after first login. However, after locking/logging out and logging back in, alt+shift stops responding, requiring toggling ccsm/commands to make it switch layouts again. KB layout switch using ctrl+shift works at all times (but bug #1683383 rears it's ugly head whenever I'm trying to copy/paste from/to terminal using ctrl+shift+[CV]). KB layout switch using super+space never works for me. No keyboard shortcuts at all work on lightdm login screen.
