i enabled "Swap ESC and CapsLock" in "System Settings -> Input Devices -> Keyboard -> Advanced -> Configure keyboard options".  this was working fine until i switched my keyboard model (in "... -> Keyboard -> Hardware -> Keyboard model") to "Apple | MacBook/MacBook Pro", which corresponds to the true model of my primary keyboard.  after i did that, ESC and CapsLock were no longer swapped, regardless of the keyboard i used, and (as a separate but seemingly related issue) layout switching exhibited inconsistent behavior in various applications.

changing the keyboard model setting back to "Generic | Evdev-managed keyboard" provides a reliable workaround.

Reproducible: Always

Steps to Reproduce:
1. enable "Swap ESC and CapsLock".
2. select keyboard model "Apple | MacBook/MacBook Pro".
3. press ESC.

Actual Results:  
the settings are set as desired, but pressing ESC triggers an ESC instead of toggling CapsLock.

Expected Results:  
either one of:
  * pressing ESC should toggle CapsLock.
  * attempting to enable "Swap ESC and CapsLock" and "Apple | MacBook/MacBook Pro" (and similarly failing combinations) together should be prevented in the UI.
