I assume you mean Redhat 4.1.

First make sure you have the right video card driver installed.

You have to edit the file /etc/X11/XF86Config
If you are a beginner, and are not familiar with emacs or vi, just type "pico /etc/X11/XF86Config"
Then things get a little tricky. Go down near the bottom. Find the "Screen sections" part. You'll see a line called "Modes." This is an order of preference for what mode you want. Insert something like "1024x786" as the first item in the line.

I can access the configuration, but can't adjust the resolution still!

What happens when you try? Does it just not change anything, or does your monitor go blank?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

It seem I can't set the resolution right, and the X-Window won't start!

Sounds like you're trying to set your resolution to more than your monitor can handle. Try something less ambitious, or a lower refresh rate.

I have a Matrox Mistique 4MB and Sony 19" monitor, in Win98, can even try on 1024*768 32 Bit colour, it's no problem, I try even smaller resolution in Linux, but still can't get it working.

Are you sure you have the correct video card driver installed? If not, you won't get anything to work right.
