Openssh and the perils of encrypted home

Let’s say you have just prepared a new server and you make all your stuff.

This may happen if your program requires special startup parameters, or simply because it requires a terminal to run in, ala’ Matlab. Creating a launcher on the desktop is not simply as right clicking to ‘create launcher’ as it was in older versions.
I wandered a while before finding my answer here (thanks to Bruno Pereira), as others where that useful to me.
