I started with a VM of Ubuntu 19.10. I applied all updates and installed Chromium and Brave Browser. When I try viewing emoji (E.G. getemoji.com) they appear to be rendered by DejaVu Sans (black and white). The system already has Noto Color Emoji installed. How do I give Noto Color Emoji precedence? I've followed several fontconfig tutorials, but none of them have worked. I've had success by reinstalling Noto Color Emoji, but I haven't been able to figure out what reinstalling is doing that makes it work. Also, I'm working with someone who says reinstalling did no work for him.

One way:

1. Create this file:

   ~/.config/fontconfig/conf.d/10-prefer-emoji.conf

2. Give it this contents:

   <?xml version="1.0"?>
   <!DOCTYPE fontconfig SYSTEM "fonts.dtd">
   <fontconfig> <alias> <family>sans-serif</family> <prefer> <family>Noto Color Emoji</family> </prefer> </alias>
   </fontconfig>

Edit:

That seems not to be sufficient (see comment).

$ fc-match -a | head -2
DejaVuSans.ttf: "DejaVu Sans" "Book"
NotoColorEmoji.ttf: "Noto Color Emoji" "Regular"

So maybe change the contents to this variant:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig> <match target="pattern"> <test qual="any" name="family"> <string>sans-serif</string> </test> <edit name="family" mode="prepend" binding="strong"> <string>Noto Color Emoji</string> </edit> </match>
</fontconfig>

That seems to make a difference:

 $ fc-match -a | head -2 NotoColorEmoji.ttf: "Noto Color Emoji" "Regular" DejaVuSans.ttf: "DejaVu Sans" "Book"
