I tried installing debian linux to my system . Everything went well but I was not able to configure my Xserver. It was working well with redhat.... please help

You really should consult the handbook next time. It has answers to common questions such as yours as well as guides. Here's a link that should help you out.

We need a little more detail about your question as well.

You need to edit your XF86Config file...most likely to bring the resolution down. You might not have the drivers installed for your specific video card (generic linux ones install by default) and your monitor might not be specified either. This means that your monitor might not or video card might not support higher resolutions. If during the install or config of your XF86Config you specified a higher resolution than 800X600 then you xserver will most likely crash if the higher res isn't supported. Pump this resolution down by going into your CF86Config and editing it manually. For more information: Try the XF86Config Manual page

As root, try this:

It's not perfect, but it will probe your system's hardware to see which configuration variables should be set. This will give you a good starting point with XF86Config. You can test the configuration file it generates by following the instructions it gives you after it completes.

As always, read the manpages. In this case, man XF86Config

OK, guys, we are starting to sound too much like a ******* *nix admin(atleast I was). Even though one must read the documentation on what ever you are working on.
I rarely tell people to man something, unsless the question is really vague. But in my case I needed to know how far you were or are along in the process.
I remeber when I was first learning linux everyone told me to man,man man man man. I wanted to manhandle those guys. But I shut up and read the man pages anway. so , I don't like giving the man as a reply to someones question for a quick fix.


cheers

I always suggest to read the manpage(s) because that's where the core documentation is located. Granted, you can search Google.com to find answers, but what happens when you can't get online to use Google? Suppose you're trying to find out how to set your IP address so you can get online. Knowing where to find the information is one of the key things in both Linux and UNIX, and surprisingly, when you get in the habit of reading the manpage(s) for something, you tend to retain the information you've learned from it better and longer than if you just copy/paste something found on the Net.

I also mention the proper manpage(s) for the specific item in question as a reference for further information, along with other sources, if available (like info, apropos, etc.) If anyone is seriously wanting to learn *nix as a trade and not just a hobby, knowing where to find the information to a particular system is crucial.

I may not be the most knowledgable person when it comes to Linux and/or UNIX, but I've been using Linux for the past 8 years (Slackware & Debian) and UNIX (Solaris, HP-UX, and FreeBSD) for about 6, so I know the easy way to find answers to something in a hurry, mainly because I RTFMP :)

Thanks all of you ...... I did give a try but ahhhh no result...... I am switching back to Red Hat....Maybe I give another attempt some other time

Yeah, giving up is the way to go. It's alot easier less pain.
Debian probably doesn't even work.
Check out Mandrake, SuSe or Fedora.
Yeah, best to give up instead of seeking help.

Nice. We're supposed to be assisting people, not browbeating them because something they were trying didn't work.

Thanks "The Ogre" its making me feel better
