To install TrueType fonts for Xorg on a Debian Linux system, follow these steps:
Download the TrueType fonts that you want to install. You can either download them from a font website or copy them from another system.
Copy the fonts to the /usr/local/share/fonts
directory:
sudo cp FONT_FILE /usr/local/share/fonts
Replace FONT_FILE
with the path to the font file.
sudo fc-cache -f -v
This will rebuild the font cache and make the new fonts available to Xorg.
