First of all, you're going to irritate a lot of people by referring to "linux 8.0". There is no such thing. The "8.0" is the version number of whatever distribution you are using, and that is the information we need.
Onward...
If you have a graphical login (xdm, kdm, gdm) it IS running X so unless you have killed the login, there's no reason to issue 'startx'. Just log in with your root login (or whatever user) and it should give you your distro's default operating environment (KDE, GNOME, etc.)
As far as your home network, we can help you if you give us some information on it, such as:
How many other machines are on it?
Do you have any networked printers you need to access?
Is your network connected to the internet?
If so, it is via dial-up and M$ internet connection sharing?
or are you on ADSL?
If on ADSL, do you have a modem connected to one machine or a router connected to your hub?
Things like this wil make it a lot easier to help you.
Also, if you want to learn Linux, I'd recommend using the Slackware distribution. If you just want to use Linux, you're probably fine with Mandrakw (which is what I'm assuming your 8.0 refers to).
Hope this helps, and do post back with that info!
