I have Ubuntu MATE on a VM and could reproduce your first issue there, i.e. it's present only when Neo 2 is not first in the list of keyboard layouts.
Consequently this is probably an xkeyboard-config issue and not specific to gnome-control-center. And the issue is reasonably upstream in nature. I found this open upstream issue regarding Neo 2: https://gitlab.freedesktop.org/xkeyboard-config/xkeyboard- config/-/issues/14 Can't tell if it's related to your observations. If not I would recommend you to file a new issue upstream. If you do, please post a link to it here for tracking purposes. ** Bug watch added: gitlab.freedesktop.org/xkeyboard-config/xkeyboard-config/-/issues #14 https://gitlab.freedesktop.org/xkeyboard-config/xkeyboard-config/-/issues/14 ** Package changed: gnome-control-center (Ubuntu) => xkeyboard-config (Ubuntu) ** Changed in: xkeyboard-config (Ubuntu) Importance: Undecided => Low ** Changed in: xkeyboard-config (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1909347 Title: Keyboard layout used in the second place breaks keymap To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xkeyboard-config/+bug/1909347/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
