Installing X system/apps on headless server

[kalasend]

Hi all,

Background:
I need some help regarding install X server/apps on a headless(ie. no monitor, no graphic device) server. The server is in fact a virtual one by Amazon EC2. So there's no monitor nor any graphics hardware. Fedora server (6, i believe) is pre-packaged.

The problem is that I want to be running a server app with a GUI. The app won't start without the GUI (and I probably need to tweak a few things through its GUI too).

I plan on setting up very very bare minimal X on the server and then uses NX for remote access. Can somebody shed some light here?

Simply put, my questions are:
1) What would be the minimal list of package i need to install?
2) Where can I find docs about installing and setting up NX? I could only find very fragmented/outdated docs about it.....


Thanks a lot!
B
