Intro to X, Basic Tweaks for XFree86

"Do you have XFree86 version 4 running on your computer but haven't gotten it working just the way you want it? Maybe there are some features you would like to take advantage of, but don't know how. Or maybe you'd just like something more to experiment with. If you still can't even get a graphical screen, or the resolution isn't high enough for you, then you should seek information on a setup program called xf86config or XF86Setup. But if you need some configuration beyond that, then this article is for you."
