Font Configuration on Fedora: Using Open Source Fonts

Fedora’s default font rendering works but benefits significantly from installing current font versions and tuning fontconfig. This guide covers practical font configuration using only free software and fonts available in standard repositories.

Installing fonts

Fedora ships with Liberation fonts, but ensuring you have version 2.x (which renders substantially better than 1.x) is the first step.

From repositories (recommended)

The simplest approach:

sudo dnf install liberation-fonts dejavu-fonts noto-fonts noto-fonts-cjk

Verify the installed version:

fc-match -v "Liberation Sans" | grep version

This should show 2.x. If your system has an older version, update:

sudo dnf upgrade liberation-fonts

Manual installation (specific versions)

If you need a version not in repositories, download from the Liberation fonts repository:

# User-wide installation
mkdir -p ~/.local/share/fonts
tar -xzf liberation-fonts-ttf-*.tar.gz
cp liberation-fonts-ttf-*/LiberationSans-*.ttf ~/.local/share/fonts/

# Rebuild cache
fc-cache -fv

For system-wide installation:

sudo mkdir -p /usr/share/fonts/truetype/liberation
sudo cp liberation-fonts-ttf-*/LiberationSans-*.ttf /usr/share/fonts/truetype/liberation/
sudo fc-cache -fv

Configure fontconfig

Fontconfig controls how applications select and render fonts. Create ~/.config/fontconfig/fonts.conf for user-specific settings or /etc/fonts/local.conf for system-wide changes (requires sudo):

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
  <!-- Default font aliases -->
  <alias>
    <family>sans-serif</family>
    <prefer>
      <family>Liberation Sans</family>
      <family>DejaVu Sans</family>
      <family>Noto Sans</family>
    </prefer>
  </alias>

  <alias>
    <family>serif</family>
    <prefer>
      <family>Liberation Serif</family>
      <family>DejaVu Serif</family>
    </prefer>
  </alias>

  <alias>
    <family>monospace</family>
    <prefer>
      <family>Liberation Mono</family>
      <family>DejaVu Sans Mono</family>
    </prefer>
  </alias>

  <!-- Font rendering settings -->
  <match target="font">
    <edit name="antialias" mode="assign">
      <bool>true</bool>
    </edit>
    <edit name="hinting" mode="assign">
      <bool>true</bool>
    </edit>
    <edit name="hintstyle" mode="assign">
      <const>hintslight</const>
    </edit>
    <edit name="rgba" mode="assign">
      <const>rgb</const>
    </edit>
  </match>
</fontconfig>

The hintslight setting provides good balance for screen rendering—it applies enough hinting for clarity without distorting letterforms. hintfull can appear too bold on most displays.

Reload the cache to apply changes:

fc-cache -fv

GNOME font settings

If running GNOME, configure fonts through dconf. You can use the GUI editor or command line:

gsettings set org.gnome.desktop.interface font-name "Liberation Sans 10"
gsettings set org.gnome.desktop.interface document-font-name "Liberation Serif 11"
gsettings set org.gnome.desktop.interface monospace-font-name "Liberation Mono 10"

To open the GUI editor:

sudo dnf install dconf-editor
dconf-editor

Navigate to org.gnome.desktop.interface to adjust font names and sizes. Most GNOME and GTK applications respect fontconfig settings immediately, though some may require a restart.

Recommended font packages

Beyond Liberation, these open source fonts improve rendering coverage:

sudo dnf install ibm-plex-fonts google-roboto-fonts

• DejaVu — excellent serif and sans-serif with extensive Unicode support
• Noto — covers most writing systems; particularly useful for CJK characters
• IBM Plex — modern professional typeface family
• Google Roboto — clean sans-serif optimized for screen display

Verify configuration

Test your settings:

fc-list | grep -i liberation
fc-match -v sans | head -20

The second command shows which font is selected for sans-serif requests and its rendering properties. Open a terminal, web browser, and text editor to verify fonts render cleanly without pixelation or excessive boldness.

If a specific application ignores your fontconfig settings, check whether it uses a toolkit other than GTK (Qt applications, for example, may require separate configuration). Most terminal emulators respect fontconfig directly—configure your preferred monospace font there as well.

After applying fontconfig changes to /etc/fonts/local.conf, always run sudo fc-cache -fv to rebuild the system font cache.
