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 installed Sarge, but am having difficulties with
the video. The output is pixelated and the only resolution setting
available is 640X480. lspci reports that the graphics card is:
0000:00:01.0 VGA compatible controller: Intel Corp. 82810E DC-133 CGC
[Chipset Graphics Controller] (rev 03). The monitor is an NEC
Multisync II. The refresh rates are set according to monitorworld.com
The box is a pieced-together-from-scraps machine based around a Compaq
with a 633 MHZ Celeron
I have been told that the problem may be in the bios, that I need to set the video ram to the max. Does this seem like a possibility? I don't want to start screwing around with stuff unless I am relative sure it will make a (positive ) difference.
Resetting the shared memory is no biggy. Get into the bios and you'll probably find the graphics controls in peripherals or under advanced (just have a look around) and set the memory to whatever your system can afford. Bear in mind that it's reserving part of your RAM. You can now reconfigure the X server. Do as root dpkg-reconfigure xserver-xfree86 and when you get to the grahics card section enter the amount of memory you set in the bios and then save the setting.
First, to get more colors you'll need to change your DefaultDepth to 24 (or 16 or 8).
Identifier "Default Screen"
Device "Generic Video Card"
Monitor "Generic Monitor"
DefaultDepth 4 <----- change to 24
Also try changing the "Generic Video Card" section to:
Identifier "Generic Video Card"
Driver "vga" <----- change to "i810"
VideoRam 256 <----- delete this line
So it looks like:
Identifier "Generic Video Card"
After making these changes, log out to the login window and restart your X server by pressing Ctrl-Alt-Backspace.
If my guess is wrong and your onboard video is NOT i810, then the X-server will fail to restart and you'll be stuck with a text login prompt. In that case, login (in text mode) and change the video driver to "vesa". You can do this with the commands:
"su" lets you log in as root, it will ask you for the root password.
vi is a console text editor. The basic vi commands you need to know are:
"i" --- enters "insert mode". You'll want to press "i" once after the program starts to put you into "insert mode".
escape key --- exits "insert mode"
"ZZ" --- saves the file and quits. You need to toggle OFF insert mode in order to enter this command. Otherwise, pressing "ZZ" merely types in ZZ where the cursor is.
":q!" --- quits without saving any changes. Use this if you mess up accidentally.
IsaacKuo: You sir are a gentleman, scholar and genius! Your solution solved my problem. However, now the image area is too great vertically for my monitor. The monitor does have a 'V Size' control, which is set to the smallest. I can view everything, but I have to move the image area around on the screen with 'V Posi'. Any suggestions?IsaacKuo: You sir are a gentleman, scholar and genius! Your solution solved my problem. However, now the image area is too great vertically for my monitor.

Your monitor may have difficulty fully supporting the attempted resolution/refresh rate. Hmm...
...okay, I just did a google search on NEC Multisync II. Good lord, that's an antique! According to www.monitorworld.com, that monitor's max resolution is 800x600, with a max refresh rate of 80hz.
Your monitor section reflects the correct refresh ranges, and I'll bet the x-server is attempting to max it out at 80hz. Unfortunately, your old monitor possibly can't handle a full 80hz anymore at 800x600 (if it ever could).
Try reducing the vertical refresh range from 50-80 to 50-60. This should start up 800x600x60hz, which hopefully your monitor can handle alright.
