Hi !
After I had installed trisquel-mini 6.0 on amd64, I had only a terminal and I was not able to start lxde or a graphical user interface.
$ startlxde
error: can't open display
Finally I installed xorg and I use startx to launch the desktop environment.
I think we should not have to download something in order to use lxde.
