I started writing this in the Fedora forum but decided it might fit better in the Newbie forum...
I just did a "minimal" install of FC3 on a box that will be used as a home server. It has no screen (except one temporarily connected during install) and I SSH in from my RH9 desktop. X is not installed on it.
The thing is, I thought that some GUI programs would still work over SSH? They did on my previous FC2 installation. E.g. when typing emacs in my SSH window, the X version would automatically appear on my RH9 box. Now it does not. And the programs I was really trying to use (emacs was an additional test), like system-config-users will not run because they "require a running X server" On my previous install, I did not choose minimal, I manually deselected pretty much everything I did not want. I suppose it is quite possible some X things were automatically installed because I chose programs that required them.
Anyway, I guess my real question is: Do I need to run X on the server to use GUI tools remotely?
