Theoretocally, you shouldn't= need to change any settings on the remote computer. The remote side will n= ot know that the client is using a German layout, but the keys should still= work as intended. Guacamole will forward key events based on key identity,= not key location. The VNC server should perform any necessary translation.= In fact ... the VNC standard requires the server to do this.
