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.

Since installing this (k)Ubuntu, I'm experiencing some problems that I can't solve (yes I have searched here, and via google, but can't fathom out any of the possible answers).
A, I can't open the user interface for my partners login, despite trying to modify the "files" that login errors seem to suggest are causing the problems i.e. .dmrc - which errors with "must be owned by the user, not being writable by others, and must have permissions of 644".
I think I've changed what needs to be changed, but it seems to make no difference.
B, When trying to log into her UI for Kde, it will either just not get in and return to the login dialogue box, or sometimes I get a message about "kstartupconfig not starting. check the installation".
I can't even work out where to start with that - though I did find some stuff that suggested that I might need to re-install KDM (I've re-installed absolutely everything that seems to be KDE related with synaptic).
C, Although I've added/activated the root account and modified the .kderc to allow root graphical logins (yes, yes, I've read all that garb that Canonical/Ubuntu say the "dangers" of logging into root graphically), "it" will only allow me to login to root from the main login screen, if I try to either do "sudo kdesu konqueror" or su to root and then try konqueror, it errors me out telling me that it can't connect konqueror to the X server.
If anyone has any ideas how to get round these, I'd be very greatful.
Check Launchpad for bug reports before you manually fix stuff on a clean installation: there are so many users that issues tend to get reported fairly quickly.
The nice thing about Ubuntu is that you really don't have to tweak it to make it work. I've had to unlearn that habit a bit since switching .
I'd also suggest that you look into sudo before going back to the old way of direct root logins. On Ubuntu the gksudo command lets you launch graphical apps as root from the desktop, and Kubuntu has kdesu, so root logins really are redundent.
