Hi Vamshi, this means that you have to configure your X server. Depending on your version of XFree86 and your graphics card there are several things to consider. For example, if your are running XFree 4.0 or later, there should be a 'Load "glx"' statement in your XF86Config. But there are too many issues to discuss them here.
If you are new to Linux I would suggest getting a recent Linux distribution. Most of them should configure things correctly now.
