I use Debian 9 + fluxbox so there are no 1click enable remote desktop solutions:

The problem with tightvnc, that (at least by default) it will spawn a completely new X session. I don't want that, rather to connect to my currently opened Xorg+fluxbox desktop on my laptop.
Any ways to do this? Am I forced to use commercial software like RealVNC?
