Thread: KDE Display Properties

  1. KDE Display Properties

    Hi all,

    I changed my laptop's display resolution and ratio within sax2 from 1024x764
    to 1280x800. However, KDE still displays as 1024x764!

    I've tried changing the display resolution via the Control Center, but it
    only offers 1024, 800, and 600 resolutions.

    System: Acer 1414 with 15.4 WXGA TFT LCD
    KDE Version: 3.4.2 Level 'b'
    SuSE 10.0 Release: 2.6.13-8-default

    Any ideas will be greatly appreciated,

    AWW

    Are you sure your graphics card does support 1280x800, check your
    /var/log/Xorg.0.log (if you use an old distro, check /var/log/XFree86.0.log).

    If X has more than one resolution, it will always choose the highest one that
    the driver/graphics card does support.

    Here's the log entries:

    I must say, I find this log-file very difficult to interpret.
    As far as I can see, xorg depends on the DDC response
    from the monitor or video card (which?).

    As it happens, my laptop (Sony Picturebook) does not respond to this:
    (II) ATI(0): VESA VBE DDC supported
    (II) ATI(0): VESA VBE DDC Level none
    (II) ATI(0): VESA VBE DDC transfer in appr. 2 sec.
    (II) ATI(0): VESA VBE DDC read failed

    I put in my own Modeline (which someone with a Picturebook gave me).
    I've never been sure if this is the best (or only) thing one can do
    in these circumstances.

    Is there any documentation explaining the output of the log-file?

    I've always assumed X tries the resolutions in the order they appear
    in the "Modes" line (in xorg.conf),
    which admittedly usually has the highest resolution first.

    No, it's not an available resolution, "(no mode of this name)", you can try to
    create a modeline that you call 1280x800, I suggest you try to use Colas
    modeline generator: http://koala.ilog.fr/cgi-bin/nph-colas-modelines

    Think this is the monitors, but not sure.

    You could try to look at the online manual for Xorg/XFree86, but I doubt there
    is a good description of the logfile.

    If I have understood the things I have read right, say you have

    Modes "1152x864" "1024x768" "1280x1024"

    The highest one is selected for the "dekstop size", in this case 1280x1024,
    but the "screen size" will be "1152x864", which makes you won't see the whole
    desktop, but when you get to a corner of a screen it will "scroll" to that
    direction on the desktop (called panning I think). This as long as the highest
    resolution is supported by the card, otherwise it's dropped.

    Think there are a lot more skilled people to give an answer on this at
    comp.os.linux.x
