Thread: Screen resolution

    Screen resolution

    i have been going through all these guides, and i can't seem to find one that will tell me how to adjust the res on my monitors. i am running redhat 7.3, does anyone know how to do this by the KDE menu?

    You should be able to change screen resolutions with CTRL ALT + or CTRL-ALT -

    This only works if you have multiple screen resolutions configured in your /etc/X11/XF86Config-4

    Re:Screen resolution

    that didn't seem to work. any other ways?

    also, do you know of any straight forward guides on how to set up a second monitor with a separated desktop?

    Hmmm that should work if your XF86Config-4 is setup right.

    Setup a second monitor on a different video card?
    Look specifically at Multihead and Xinerama, but it has quite a bit on X in general.

    This hasn't been updated to the latest release.

    actually, i have a matrox G450 dual head. will it work the same?

    update: i tried to use xinerama, but it told me this:
    [greg@localhost greg]$ X +xinerama

    Fatal server error:
    Server is already active for display 0
    If this server is no longer running, remove /tmp/.X0-lock
    and start again.


    what can i do from here?

    Re:Screen resolution

    did you read through the Xinerama howto?
    it seemed fairly clear to me.
    did you configure both monitors?
    does the matrox have two PCI ids?
    you have to run it with $startx -- +xinerama like it says in the howto??

    I believe do use dual head on Matrox cards require the drivers from Matrox's website.

    Check out this readme on Matrox's Linux drivers.
    ftp://ftp.matrox.com/pub/mga/archive...nx200notes.txt

    I will check the XFree86 docs when I get the chance and see it the XFree86 drivers support dual head.

    Ok dualhead on Matrox cards is apparently supported by XFree86. I found the link below. It has a real good excerpt from a sample XF86Config-4 setup for dualhead. Although you still might want to use the drivers from Matrox's website.

    sweet, getting both monitors going with independent desktops is my next project. once i know that, i will know most of the important things that i need to about setting up my PC. if only i could figure out this confounded mouse.....

    Re:Screen resolution

    i did use matrox's drivers when i was using enigma. they were pretty craptacular, if i remember. windows were very difficult to move between screens and something happened to the text in the system. it wasn't fun
