Describe your issue

It seems the change in da7197d killed one of the vnc features where you can expose screen like this via module. This performs significantly better than x0vncserver and with enough network latency and bandwidth, it performs as good as nomachine.

Section "Module"
    Load "vnc"
EndSection

Section "Screen"
    Identifier "Default Screen"
    Option "SecurityTypes" "None"
EndSection
