Changing resolutions in xorg

[dan@george]

I know this monitor is capable of 1280x1024 resolution. However, even though I've specified that in my /etc/X11/xorg.conf file, when I go to K --> System --> Screen Resize and Rotate in KDE, 1024x768 is the largest resolution listed. Here's the display subsection of my xorg.conf file:

    Subsection "Display"
        Depth       8
        Modes "1280x1024" "1024x768" "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes "1280x1024" "1024x768" "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       24
        Modes "1280x1024" "1024x768" "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       32
        Modes "1280x1024" "1024x768" "800x600" "640x480"
    EndSubsection

Am I missing something?

try ctrl alt + and ctrl alt - and see what happens

[dan@george]

Ctrl-alt-plus makes my screen all screwy with diagional lines and stuff -- like watching a TV on a channel you don't quite get. That happens the first 2 times I press it, and the third time it goes back to my regular resolution. Same with Ctl-alt-minus.

sounds like either your dirvers are off, or your horzontal/vertical sync rate...thats all i really got.. sry man
