Broken monospace fonts

Some apps like VSCode and Alacritty seem to be unable to load mono-space fonts correctly and use their default fonts. Been looking into this for two weeks but no bueno. Not everything is broken as apps like Kate seem and flatpak items seem to still work. It's mostly items from Nix that seem to be unable to resoolve fonts.

I've tried multiple things including resetting nix, rebasing to Bazzite (from Aurora) and few more minore things. Appreciate any pointers.

Solution

This turned out to something fishy replacing "Noto Sans Mono" files with "Noto Sans" font. That is, there's

ttf

ttf

on the system that carry the

NotoSansMono-XXX.ttf

NotoSansMono-XXX.ttf

title but are actually

Noto Sans

Noto Sans

proportional. And the trouble is, this was my system's default monospace font and also my configured font for Alacritty.

And yeah, this was not a nix problem and I'm just using the

NotoSansM Nerd Font

NotoSansM Nerd Font

that comes from the nix

nerd-font.noto

nerd-font.noto

package to get everything sorted.
