Setting up Maemo scratchbox

It's worth mentioning. When you try to setup scratchbox for maemo you probably ended up with googling and looking for this :

Xephyr cannot open host display. Is DISPLAY set?

I am almost sure that you use gnome, so enable TCP connections in GDM setup.

Unfortunatelly I resolved this weird issue while my user's scratchbox account started to acting up so obviously I need to reinstall scratchbox.
