As far as I could find out in my quick lookaround, there seems to be a lack of a default, decent font viewer-and-manager-in-one on Ubuntu. Here are some general tips I came across while checking things out:

  • Your personal fonts folder: /home/username/.fonts
  • Systemwide fonts folder: /usr/share/fonts/
  • Fontconfig cache updater: fc-cache
  • Force a font cache update (and show the checked folders): fc-cache -fv
  • Ubuntu also ships with Debian font manager: defoma

Note: This post is nothing more or less than some hints that you would rather find out about immediately.
