20-intel.conf makes screen recorders not function

Support Graphics & Display
1

My display is half broken and so i thought making my tab a second display would help me able to see things at full color. I tried achieving this using vdl-monitor and deskcreen. As expected it did work but i soon found out that the screen recorder stopped working. I figured out it was because of the 20-intel.conf file in /usr/share/X11/xorg.conf.d/. I removed it and that did fix the problem but then i wasn’t able to use vdl-monitor. I dont know the reason for the 20-intel.conf glitching out my screen recorder. Heres the content written inside the file:

Section "Device"
    Identifier "intelgpu0"
    Driver "intel"
    Option "VirtualHeads" "2"
EndSection

And heres my inxi:

Thanks for your help. Turns out it was because of DRI3. I went back to DRI2 by adding the following option to my config file

    Option "DRI" "2"

But now parts of my screen flicker. It said that theres a proper way to disable it with LIBGL_DRI3_DISABLE=1 in mesa but i dont know how to do that. Where do i do this?
