want to modify xf86config file

gonus · 11-07-2002, 09:36 PM

Looking to modify my XF86Config file so I can get differant screen sizes for games. The question I have is do I monitor it under "monitor"? This is what I have under there.

Identifier "Primary-Monitor"
VendorName "Vendor"
ModelName "Model"
HorizSync 31-64
VertRefresh 50-85
Modeline "640x480" 31.5 640 656 720 840 480 481 484 500 # 6. Versuch
Modeline "640x480" 31.5 640 680 720 864 480 488 491 521 # 5. Versuch
Modeline "640x480" 28 640 664 760 800 480 491 493 525 # 4. Versuch
Modeline "640x480" 28.32 640 664 760 800 480 491 493 525 # 3. Versuch
Modeline "640x480" 25.18 640 664 760 800 480 491 493 525 # 2. Versuch
Modeline "640x480" 25.175 640 664 760 800 480 491 493 525 # 1. Versuch

The problem I am having is games, when directed to play at a certain screen size will still not play at another screen size. I am thinking I need to add more screen sizes to the XF86Config file so that it will be possible to play them in other sizes.

Thanx for all the help

Which version of XFree86 are you using.

Newer versions (4.1 and later I think) use a simplified method of expressing display modes in XF86Config. For example:

Code:

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

As for refresh rates, you have to specify ranges in the monitor section like this:

Code:

Section "Monitor"
    Identifier  "VX900"
    HorizSync   31.5 - 79.0
    VertRefresh 60-75
EndSection

but XFree should still check the DDC for your monitor and pick the best refresh rate. Check /var/log/XFree86.0.log to see what refresh rates are being picked up.

Have you have checked the man page for XF86Config? It may confuse you further, but there's a lot of information there.

Hope it helps.
