    Information like which distro would really help someone answer this question.

    We really need to know what distro you're using. Linux is a kernel, not an Operating System.

In a Debian based distro, you should run (as root or with sudo): apt-get install xorg. This will give you an X server. In a newer Fedora/CentOS/RedHat distro, run yum groupinstall X\ Window\ System.
