    Fedora Core 3 "Frequency out of range" issue.


    Hello. I'm new here.

    At work, I am working with a Linux box that has Fedora Core 3 on it.

    I'm not a huge linux person - I don't know a lot about it, and I'm not great with it.

    Whenever I try to switch to the GUI, I get a "Frequency out of range" message on the monitor in a blue box that floats around.

    The command line interface works fine.

    Anyone know how to fix this?

    Welcome to the forums, kataris!

    Check your monitor manual for the correct vertical and horizontal refresh rates. Then from the command line, enter:

    Code:
    nano /etc/X11/xorg.conf
    Edit the file so that it contains the refresh rates that are correct for your monitor. The lines will look something like this:

    HorizSync 30-81
    VertRefresh 56-75

    After editing, save file, then restart X.

    Thanks for the quick response and welcome, ozar.

    However, that file seems to not exist on this computer.

    Any other ideas?

    Just guessing, but maybe you used a lower-case x in the command rather than the capital X as required?

    That's it.

    Heh, like I said, I'm not great with Linux. Still getting used to the whole "caps matters" thing.

    Thanks for your help, I'll try this out and see if it works.

    EDIT: Hmm, I can't seem to find the refresh rates I need to use.

    I'm searching online, since I'm not sure where the paper manual is, and all I can find about refresh rate is that it runs 1024x768@75Hz. (http://www.compuplanet.com.cy/149336...2628331_File_1)

    I thought I was pretty technically inclined, but this seems to be proving that I'm not.

    Yeah, that didn't show your horizontal sync rates, but it had some vertical refresh rates. Based on what was available, I believe you'd be safe enough to try the same rates I posted above and see if that works:

    HorizSync 30-81
    VertRefresh 56-75
    Those rates are for my similar monitor.

    Hmm..

    I tried changing them, and then I rebooted, and I'm still having the same problem.

    Did you remember to su to root before editing the file? If not, the edit might not have saved properly because you must have root privileges to edit any file outside of your own /home directory.

    I'm logged in as root.

    Does that give me root privileges? =\

    Sorry if I'm not up to snuff on Linux. I never really got into it, and only just started learning it last year when I was taught it in Computer Science 135.

    Thanks for your patience though.

    Log out of root, then back in as regular user.

    Then su to root, then edit the command again. Then restart and see if it works.
