screen resolution problems


i have read about problems with resolution problems with the intel 865 graphics chip and was able to resolve that problem with a little modification of the XF86Config-4 file. the only problem now is that it only gives me the option of 16-bit color. how can i change this so i can set it to 24 or 32 bit? i know it is supported because i am dual booting with XP and it works well there. any ideas would be greatly appreciated.
btw i am using Mandrake 9.2

In your XFree86 config file, you should have a bunch of display subsections, under your screen section, like this:
Code:
    Subsection "Display"
        Depth       8
        Modes       "1280x1024" "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes       "1280x1024" "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection
    Subsection "Display"
        Depth       24
        Modes       "1280x1024" "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection
Make sure you have one that has a depth of 24, and then check for this line:
Code:
DefaultDepth    16
and change 16 to 24. If your X server won't start after that, it means your card can't do 24 bpp (or your driver can't).
