    Cant get the same resolution i get in windows XP


    On my dual boot OS windows XP, i can get perfect resolutions way higher than 1600x1200 regardless of what these monitor specs say. Id like to do 1600x1200 on my FC4 system. When i try to set it past 1280x1024 i get a black screen with an error from the monitor saying it cant support the rates 74.9 and 60. Can anyone help me here?


    I have a proview 766b monitor.
    Its specs are: "VGA up to 1280x1024 @ 75hz."
    Horizontal Freq: 30-80kHz Vert Freq: 50-75Hz
    http://www.proview.net/pdfs/pl766s.pdf

    My Video card is an ATI Radeon 9250, that was detected as a 9200 Radeon Pro Series.

    My xorg.conf is:

    Section "Monitor"
    Identifier "Monitor0"
    VendorName "Monitor Vendor"
    ModelName "Proview 770"
    HorizSync 30.0 - 80.0
    VertRefresh 50.0 - 75.0
    Option "dpms"
    EndSection

    Section "Device"
    Identifier "Videocard0"
    Driver "radeon"
    VendorName "Videocard vendor"
    BoardName "ATI Radeon 9200PRO"
    EndSection

    Section "Screen"
    Identifier "Screen0"
    Device "Videocard0"
    Monitor "Monitor0"
    DefaultDepth 24
    SubSection "Display"
    Viewport 0 0
    Depth 16
    Modes "800x600" "640x480"
    EndSubSection
    SubSection "Display"
    Viewport 0 0
    Depth 24
    Modes "1280x1024" "1152x864" "1152x768" "1024x768" "800x600" "640x480"
    EndSubSection
    EndSection

    You should try and add "1600x1200" to that line and try to change the resolution again.

    I tried that. I tried setting it to 1600x1200 from the gnome display settings GUI box and that wrote it to xorg.conf. But in case that didnt work i added it there myself. I get a black screen from my monitor with a red box that says mode not supported 74.9 X 59.6. First those rates are fine with my monitor. 2nd Ive had the res up over 2000 on windows and it works fine, so i know its NOT a hardware problem.

    Maybe try updating your AIT drivers

    The ATI linux drivers are as nice as the NVidia ones, but they should work.

    Hope it works for you.
