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.

Problems with Nvidia graphics in slack -curent
I am using nvidia fx 5500 graphic card and still have unresolved problems with graphic. At this moment I cannot set X window system to work properly. My first attempt after installing slack -current was to install nvidia's 'blob' driver. As it is know 'blob' conflicts with 'noveau' open source driver for nvidia cards. 'Blob' cannot install with noveau running. Thus I blacklisted 'noveau' and installed the 'blob'. After I restarted the computer it seemed it is Ok, but 1) it is really very hard to set the proper value of gamma correction, contrast and brightnest, 2) after logout the X server didn't restart and computer was 'dumb'.
I have some prerequisites to suspect the 'nv' X.org native driver for bugs, but I tested and driver is ok, however it is impossible to work wit this driver, it can only accomplish 60 Hz V. refresh,
The command 'dmesg' gave this
NVIDIA taints kernel
(oops:it's clear, the kernel cannot be longer pure with 'blob' :-))
Moreover, the common configuration procedure
$ Xorg -configure
doesn't work at all. The same happened: computer is freezing, no mouse, no keyboard. I tried some X ServerFlags options like "AllowEmptyInput" but no help.
I will try to use "noveau", but as I understand it should be compiled from the source as it is a part of kernel ( why?).
Any idea what's wrong?
Additionally: in fact I have to graphic devices - nvidia on AGP and VIA graphic onboard card (VT1344). BIOS points to AGP as primary graphic device.
I don't know what the "blob" is, and I do not know anything about "nouveau".
Have you tried installing the official driver from the NVidia website, using their proceedure? Whenever the official driver is not available in the distro repository, I have found that using NVidia's intaller **always** works.
"Kernel tainting" refers to the fact that you are adding a non-free kernel module to the open kernel. This is what I call a philosophy warning. If it bothers you that your kernel isn't completely open and free, then don't install the closed source nvidia drivers and use something like noveau. If it doesn't bother you, use the closed source drivers.
1) it is really very hard to set the proper value of gamma correction, contrast and brightnest
What does this mean its hard to set Did you try nvidia-settings?

Interesting, someone had this problem just recently and solved it
by upgrading to the newest driver available (but if your card is not
supported by the newest driver, you are stuck with the "legacy" driver.)
I just saved an old computer from the trash can and it has the same
problem with the "legacy" nvidia driver...
There is a workaround for this problem.
For example, if you use kdm you can add:
to your kdmrc file. This will make the X Server restart at logout.
I still think there is something wrong with Xorg or the nvidia legacy
driver. This should work fine out of the box...
