Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am having some fun with a SIS730 card trying to get 3d acceleration to work.
Basically it goes like: compile kernel - make xf86config file - modify xf86config file.
Problem is not that it crashes after reboot - thats expected - but how it "crashes". I use kdm for login - that isn't there anymore. If i login as root i can startx. As user it wont startx. Reconfiguring kdm or xdm doesn't do anything at all.
When i use the backupfile for xf86config and copy it in there i have the same problem.
I have to do xf86config to get things back to normal - the file that is created there is identical to the backup!!
I notice from the XFree86 website the SiS730 isn't listed as supported.
My experiences are that if XFree86 won't start, it tries to use a default setting, maybe for stability/safety etc, but you lose all ability to start X.
There is also a newer configuration tool I found documented with XFree86 4.0
"The next step is to configure the X server. That is covered in detail in an as-yet unwritten document :-(. In the meantime, there are three ways to create a basic X server configuration file for XFree86 4.2.0. One is to run the xf86config utility. Another is to run the xf86cfg utility. The third option is to use the new -configure X server option:
XFree86 -configure "
I get the SIS 730 to work alright - but i try to get 3D acceleration going which is definitely not supported by the stock xfree86. I use a different driver for the card than the one included with xfree. BTW - the driver works a lot better on regular display.
But when i modify the xfconfig file for 3D acceleration i cant log into x as a user - only as root and only in kde. I use kdm as login manager; that seems to get screwed up. Tried xdm - gets screwed up too. I am going to get this sucker.
