[SOLVED] fglrx defaults to higher res than monitor supports

Hey Guys,

This could easily be an issue with my xorg.conf. Even with the "example" xorg.conf from the ATI section of the Arch Wiki I am having issues where GDM starts at 1920x1080, but my monitor only supports 1280x1024 (19inch LCD). I can change this after logging in on a per user basis, but GDM is still starting at this higher res. Here's my current xorg.conf (pertinent sections):

Section "Device"
    Identifier    "Radeon 9600"
    Driver        "fglrx"
    Busid        "PCI:1:0:0"
EndSection

Section "Monitor"
    Identifier    "Generic Monitor"
    Option        "DPMS"
    Horizsync    30-70
    Vertrefresh    50-160
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Device        "Radeon 9600"
    Monitor        "Generic Monitor"
    Defaultdepth    24
EndSection

EndSection
Section "Module"
    Load        "glx"
    Load        "dri"
EndSection
Section "DRI"
    Mode 0666
EndSection

I've always used nVidia cards in the past, so not as familiar with setting up ATI in Linux. Any tips are greatly appreciated.

Thanks!

And you ate the whole... wheel of cheese? How'd you do that? Heck, I'm not even mad; that's amazing.

Try:

Section "Screen"
        Identifier      "Default Screen"
        Device          "Radeon 9600"
        Monitor         "Generic Monitor"
        DefaultDepth    24

        Subsection "Display"
                Depth 24
                Modes "1280x1024"
        EndSubSection
EndSection
