I am new to Linux, I installed in graphical mode but was not able to boot and my monitor would display "Input Signal Out of Range Change Settings to 1600x900". I have a Branded HP Core i3 System and my monitor is HP LED Black Monitor guess 17 or 19". After 2 times installation in graphical mode, i finally installed it in TEXT MODE and was able to login in text mode but still when i run xinit the same problem, i tried to find the file XF86Config in etc/X11 but there is no such file, i tried to find using "find -name 'X*.*' still there is none. I am using Redhat Linux 5.1

I think the file is xorg.conf , but I can't be sure about Redhat.

Yes, it does look like your video card is outputting something your monitor can't handle.

i cant see anything related to screen resolution in that file, i have already checked that. it does have info for video card but where can i manually change the screen resolution?

Red Hat 5.1 or Red Hat Enterprise Linux 5.1? Either way, they are both much, much older than your system and the video card is likely not supported. It is not worth trying to backport the drivers, get a modern distribution and everything will likely work just fine.

*if* memory serves me correctly, that WAS the file that used to have various res's for X to work at, but I just took a look at mine (Ubuntu 10.10), and there's nothing of that sort there. So - someone else will have to help you out. Sorry!

The graphics unit of the Core i3 (assuming that you have an i3 with graphics unit and no dedicated video card) is to new for RHEL 5.1. Please post the output of so that we can see which video card you exactly are using. If the Intel chip is the only video device I would give RHEL 6.3 a try.

I get this
00:02.0 VGA compatible controller: Intel Corporation Unknown device 0102 (rev 09)

That means your video card driver is not present in RHEL5 . Dont use so old version linux in a new PC. Just go for UBUNTU . it is mind-blowing

You are right, I could have used Fedora and other flavours, but I want to prepare for RHCE, is it possible with UBUNTU?

I checked RHCE syllabus. almost 80% you can do in Ubuntu . But I have another suggestion.
Please use Fedora which is free version of RedHat. Fedora is based on debian packages which is required for RHCE.

Fedora is NOT based on Debian packages, it uses RPM packages.

@attakhan: If you prepare for RHCE6 then you should use a recent version, Centos 6.2. Fedora currently is not really good for RHCE, since they use systemd for managing startup services, RHEL does not.

Thank you very much for such a wonderful suggestion, I will try to find a latest version of redhat but if i wasn't able i will go with Centos.
