    xwayland: Disable the MIT-SCREEN-SAVER extension when rootless
    
    Xwayland is just a Wayland client, no X11 screensaver should be
    expected to work reliably on Xwayland when running rootless because
    Xwayland cannot grab the input devices so it has no way to actually
    lock the screen managed by the Wayland compositor.
    
    Turn off the screensaver on Xwayland when running rootless by setting
    the screensaver timeout and interval and their default values to zero
    and disable the MIT-SCREEN-SAVER extension.
