I just put my drive with my existing Ubuntu 17.10 installation from my old into my new laptop which has a different keyboard layout and I noticed that the functionality to switch keyboards is missing. There is no icon in the menu bar and pressing super + space also does nothing. It works fine at the desktop and at the lockscreen, just not in GDM… it's working on Fedora though and I did nothing fancy there either.
I compared Fedora GDM config in
/etc with Ubuntu, no luck.
Please tell me what's required to get it working.
I prefer to use Wayland, if your answer suggests configuring something related to X11 please explain why.
Here is what I see in Region & Language, there is no Login Screen button as far as I can see.
As requested by Gunnar Hjalmarsson:
$ cat /etc/default/keyboard XKBLAYOUT=de,us,gb XKBVARIANT=,intl, BACKSPACE=guess
