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.

Yes cause with su you're not allowed to make a connection to the xserver. Only as the user you're logged into as. That's the error message. So if user x logs in it's ok to run things from the terminal as user x but as root you won't be able to start GUI stuff.
still mute.. AND as always I can't even change sound level in xine and xmms.. I can mute them when turning the sound bar all down in them, but only one level is coming out as low as well as high placement of the bar.. AND the kmix doesnt work at all.. not even the "mute" in it..
realplayer is still mute.. damn fuckin sound system..
Disable the kde sound server, it doesn't work properly anyway. Never got it to work. Do you have a sound card that does hardware mixing? If not, do you use a .asoundrc file to enable software mixing?
Masand on debian you can't start a program from the terminal as root user when you're logged in as normal user. You can do it using xhost but it's not secure and not recommended. Other than that you can run the programs with sudo or gksu but no way you'll be running things via su in a normal user environment by default.
