    old monitor setup


    i got an old monitor n i am setting up libranet and i set it to 800x600 56Hz

    that is the best setting i could get to show up something up the screen

    here's how my screen looks



    as you can see, there is a repeat on the screen, u can see 3 x of 2.8.1 of bottom left of the screen because it repeats

    if you can't see, look at this


    how do i fix it?

    what kind of monitor is it? Make and model. You may have to config it manually. does it do this in text mode also? Have you tried it on another system? It may be junk... What distro are you using? you may have to set vsync and hsync. You may have to do some manual config work.

    Is this a refresh rate problem. If it is you should try changing it. Try to edit you xorg.conf file. Set your monirot to a really low resolution and refresh rate and then you can build from that.

    it can be found in /etc/X11

    You should read up on it before you do too much editing to it though

    Does your monitor appear on the manufacturers website at all??

    And i am not very good with the configuration, try reading the man pages for xorg, or popping along to there website. There has to be a guide somewhere.

    Code:
    Xorg -configure
    this might help if you can enter a console mode. :S just not sure though

    If this is an analog SVGA monitor, don't expect xorg to be able to sort it out. Xorg expects for the monitor to say what its characteristics are, but 10 year old monitors don't generally do that. I've got some references at home that I'll try to remember to pass along, but they're pretty deep: could involve working out like 8 different parameters that are related in only an abstract or complex way. Obviously, any information you can get will be helpful, so Google the model number and the manufacturer's name (there may be more than one) and post what you know.

    The resolution to start off trying is 640x480 at 60hz. It's probably what the initial POST on your PC uses (before it even starts booting). If you can see the POST, then 640x480 will work!

    Here's a modeline:

    ModeLine "640x480" 27.95 640 672 832 896 480 482 494 520 #60Hz

    This is the baseline standard, with a horizontal sync rate of 31.5khz and a vertical refresh rate of 60hz.

    If your monitor is a REALLY old monitor, it might not even be able 31.5khz. In that case, you could try 15.75khz interlaced (standard 480i NTSC timings)...but it probably isn't worth the effort.

    For what it's worth, following worked for me for a 14" monitor made in 1993 and running under Fedora Core and Gentoo:

    Section "Monitor"
    Identifier "Monitor0"
    VendorName "Jean"
    ModelName "JK1461"
    DisplaySize 280 205
    Option "DPMS"
    HorizSync 28 - 66
    VertRefresh 43 - 144
    HorizSync 35.52
    VertRefresh 86.96
    ModeLine "1024x768" 44.9 1024 1032 1208 1264 768 768 776 817 +HSync +VSync Interlace
    EndSection
