It keeps a count of open clients, increments it when a new client
connects, decrements it when one disconnects. When it decrements

Start xlogo before running xrandr if you don't want the reset.
Or xclock. Or twm, or any client that doesn't XCloseDisplay()
right away like xrandr, xdpyinfo, xset, etc. do.
