While I’m connected NoMachine completely ignores that I change the input language on my PC and this change doesn’t make any difference on the remote PC.
Hello. It is exactly the expected behavior. Client and remote session can get different keyboard layouts. In order to change the keyboard layout in a remote Xfce (or Gnome, or KDE) session, define multiple layout in the Xfce System Settings: then you’ll be able to switch layouts by just clicking on the Keyboard layout applet in the Xfce panel or using the Xfce hotkey bonded to action “switch layout”.
