Making My Dell E193FP work with gddccontrol

So I have a Dell E193FP which supports DDC/CI. But gddccontrol doesn't have a monitor description file for it.

Looking at a sample file in /usr/share/ddccontrol-db/monitors, it looks pretty simple.

Here's the file for DELA010.xml

<!--xml version="1.0"?-->
<monitor name="Dell 2405FPW (DVI)" init="standard">
        <!--- vcp(page0(04 05 06 08 0E 10 12 14(01 04 05 08) 16 18 1A 1E 20 30 3E 60)) -->
        <controls>
                <control id="colorpreset" address="0x14">
                        <value id="warm"  value="0x04"/>
                        <value id="srgb"  value="0x05"/>
                        <value id="cool"  value="0x08"/>
                </control>

        </controls>
        <include file="VESA"/>
</monitor>

so it looks like the file is fairly straightforward.

For my E193FP I ran ddccontrol -c -d -p and it gave me the vcp capabilities string, and I made a file with the name of the monitor PNP code with the suffix .xml for DEL700E.xml.

I took the vcp string and copied and pasted it into my DEL700E.xml like so, along with an include line to include the VESA.xml file as well.

<!--xml version="1.0"?-->
<monitor name="Dell Dell E193FP (VGA)" init="standard">
 <caps add="(vcp(04 06 08 0E 10 12 14(05 08 0b 0c) 16 18 1A 1E 20 30 3E 62 68(00 01 02 03 04) 38 39))"/> 
        <include file="VESA"/>
</monitor>

and copying it to the /usr/share/ddccontrol-db/monitor directory:

sudo cp -v DEL700E.xml /usr/share/ddccontrol-db/monitor/

and now gddccontrol doesn't give me a "zero" tab anymore, and I can change brightness and contrast.

Yay!
