    ADC Apple Studio Display Problems for PPC Debian

    I installed Debian on my Power Mac G4 Tower, Specs:

    800Mhz PPC
    256MB SDRAM
    ATI Radeon 7500 (ADC/VGA port)
    17" ADC Apple Studio Display (Model Number: M7649
    Apple Studio Display 17 (LCD) - Technical Specifications

    No problems during the installation except that I can't use my Studio Display. I can however plug in a VGA monitor (17" LCD) and it works great (it even is working with the correct resolution). Likely an xorg.conf problem. The ADC monitor works fine until gdm starts. It is just a Black screen (The system loads normally but there is no display). If I use both monitors plugged in I get the same thing on the ADC monitor but the VGA displays fine again.

    My Xorg.conf follows

    Yes I am experiencing issues with the same display.
    This time, instead of nothing, I have a severely offset display.
    Just the top left corner of the whole desktop.
    So I always see the top header of any dialog box and I always have to drag it up.

    Unlike forcing higher resolutions on a laptop, the screen's "window" doesn't follow the mouse's tracking, so I'm constantly stuck at the top left corner and can never see the items in the "administration" menu after the items starting with the letter "p".

    I managed to change resolutions, but all I got were smaller views of the same corner.

    Somebody please help, I'd like to keep using this apple display as it really helps cutting down on desktop cable clutter what with the integrated power/display/usb cabling and all.
