Jak zainstalować startx

sudo aptitude install xinit

then once it is installed you have to create or edit your
$HOME/.xinitrc file, and write in there

something like this:

#!/bin/sh
exec startfluxbox #if you want to run fluxbox desktop
exec gnome-session #if you want to run gnome desktop
exec startkde #if you want to run kde desktop
