Monitor driver documentation is missing

Asked by William F Pearson

My monitor, LG L204WT, is not available from the list. I seems there is a way through the interface to add a "driver." I assume this is not a binary driver, it is instead a configuration file. Where can I find one for my monitor? I'm perfectly capable of writing my own if the format is documented.

The "driver" for a monitor is a text file with the extension .inf, in case we're talking Windows. It should be located either on the website of the monitor manufacturer, or on an installation CD that came with the monitor itself. For example, my monitor ADI P750 has a Windows driver called P750.inf (or something like that). The file is simply a text file with various sections describing monitor parameters.

I assume you're running the latest Ubuntu, which has the facility to import a Windows driver, i.e. extract all the information from the file. If so, just present the .inf file to the program. If you're not running the latest Ubuntu (Gutsy), you can set the monitor manually. I described this procedure in another answer (#14447), so please refer to it. What you need is your vertical and horizontal refresh rates, then you insert them into the appropriate file and you're done. Also, you might want to change the available screen resolutions. You can do this by editing the section labeled "Screen" by simply adding resolutions to the "mode" line in subsections labeled "Display". For your reference. I'm posting the relevant sections of my /etc/X11/xorg.conf file.

Section "Monitor"
        Identifier "ADI P750"
        Option "DPMS"
        Horizsync 30-97
        Vertrefresh 50-150
EndSection

Section "Screen"
        Identifier "Default Screen"
        Device "nVidia Corporation NV40 [GeForce 6800]"
        Monitor "ADI P750"
        Defaultdepth 24
        SubSection "Display"
                Depth 1
                Modes "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth 4
                Modes "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth 8
                Modes "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth 15
                Modes "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth 16
                Modes "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth 24
                Modes "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

I configured my monitor manually I was unaware that this application could import a Windows driver. How cool. I'll test it out tonight.
