Hello and greetings fellow Zaurus owners.
I have just installed Open Zaurus & it seems to boot fine. What now?

I have logged in as root & issued a few basic Linux commands and everything seems fine. But I do not know how I can start a desktop/Xserver or even if I have this software installed.
Question: Do I need to install a window manager and X server(or alternative), or is it already installed I just need to issue some commands?
TIA
