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 have freshly installed an Ubuntu 10.04.1 by internet.
All is running well, but my nice values are all set to 0. Is there a script that handles these at boot time? How can I reset them to "appropriate" or "normal" levels (e.g. not all at 0)? I know in other installs, my nice levels vary depending on the process and the user.
Attached is a screen shot of my gnome-system-monitor, and aside from init, which I had set to -15, all others are at 0.
Linux AMD-LNX000 2.6.32-25-generic #44-Ubuntu SMP Fri Sep 17 20:05:27 UTC 2010 x86_64 GNU/Linux
I understand 0 is a default nice level; however, I have not encountered a Linux system where all processes have a 0 nice level. I frequently see daemons at -5, or something, and other root services at -15.
Obviously, this posting is more related to performance than it is an actual problem.
If you have suggestions, I welcome them. Perhaps, I should work with SysV and chkconfig and check other Linux systems to see how they perform.
I am going to run the "Live CD" portion of this Ubuntu installation. This should be a good example to what the nice levels should be per each process. Of course, this will not determine special programs added to the install.
Does anyone know an in-system command to print out processes and their priorities to stdout?
