How to tell intel graphics to use my custom EDID file?

Question

As the topic says:

xorg is related to unix or linux, and it allows you to specify a custom EDID file for the monitor. — cas, Jul 14 '16 at 06:28

Assuming you're talking about X, you can add a CustomEDID option to the Monitor section of your /etc/X11/xorg.conf. For example, I have the following in xorg.conf on my mythtv box:

Section "Monitor"
    Identifier "LG 42LD560"
    VendorName "GSM"
    ModelName "LG TV"

    Option "UseEDID" "True"
    Option "CustomEDID" "DFP-1:/etc/X11/LG-42LD560.edid.bin"
EndSection

I did this years ago and I can't remember where i got the edid file from. I think I may have extracted it with get-edid from the debian package of read-edid (I very vaguely recall something about getting a corrupted edid in X but it was OK if fetched from a VT before X started)

Yes, thats exactly what I want to do. I already have the EDID binary for my monitor but have heard that intel drivers _might_ not support custom EDID's like NVIDIA and AMD does. At the moment I use my custom EDID with a NVIDIA card under Debian, but want to take that old Nvidia card out and use the onboard Intel graphics. – Rimfire Jul 14 '16 at 07:31

I doubt `CustomEDID` apply to `Monitor` section... – malat Nov 14 '16 at 12:54
Where do you think it would apply? for the mouse? your doubt means little in the face of several years of actual experience that X worked (and still does) correctly with my LG TV using a custom edid file in the Monitor section and didn't without it. It means even less when you take into account the **fact** that the CustomEDID option is specifically intended for use within the Monitor section. – cas Nov 14 '16 at 17:28

I can confirm what malat said: both `UseEDID` and `CustomEDID` must be in the `Device` Section. Intel ignores `UseEDID` while `CustomEDID` is totaly broken in my braswell. – Elvis Dukaj Mar 21 '17 at 09:21

The one that worked for me :

Section "Device"
   Identifier  "Device0"
   BusID       "PCI:00:02:0"
   Option      "LVDS-1" "MonitorLVDS1"
   Option      "DP-1"   "MonitorDP1"
   Driver      "intel"
   Option      "CustomEDID" "DP1:/etc/X11/edid.bin"
   Option      "UseEDID" "true"
EndSection
