Hi peeps I'm a noobs on this site help.. I have a FC4 running a GUI mode. My question is how will I uninstall X windows on the system because I'm not using it anymore.. BTW I'm using an FC4 help

If you don't have a space issue then leave it.
There's really no point in removing components just because you don't use them any more.

that's my very big problem I have a space issue on my USR directory... advice how to remove it.. my /usr directory is 85% already and I tried df and found out that x is taking up more space. Need to uninstall it to free up space and I can manually run update patches on my linux.. do help me

You can't uninstall X if you still plan to use the GUI. You might be able to uninstall optional components that you're not using though. "rpm -qa" will list all packages installed. See which X pacakges you don't use and "rpm -e packagename" will erase what you're not using.
