Infinality Remix

⚠️ Deprecation Warning: On new versions of FreeType, the Infinality patches cause various rendering glitches and/or segfaults (see issue #15). Only the fontconfig-infinality-remix package will be updated going forward for a limited time. Please consider alternatives to Infinality as using older versions of freetype can be a security hazard.

If anyone with FreeType experience would like to maintain freetype-infinality-remix please get in-touch!

Background

The Infinality set of patches for the FreeType font rendering infrastructure has provided improved font rendering on Linux based desktops for over a decade. However, over time, porting the patches to the latest libraries has become more and more difficult as the two codebases diverge. Often times entire versions of FreeType are left unpatched, sometimes resulting in broken desktops and a poor user experience.

Until 4K monitors are the norm, good font smoothing should remain an important priority for the Linux desktop.

Project Goals

The Infinality Remix repository has been created to address this problem. This repository is based off the infinality-ultimate-bundle and has the following goals:

1. Porting, updating, and refactoring the Infinality patch set to remain compatible with upstream FreeType and Fontconfig.

2. Cleaning up and modularizing the Fontconfig configuration files.

3. Investigating and finding solutions to font rendering issues to improve the visual quality and consistency of text on Linux.

What's Provided

The following packages are provided:

Installation

1. Remove all previous Infinality FreeType, Fontconfig, and Cairo packages and replace with the stock libraries.

2. Remove any broken Infinality symlinks in /etc/fonts/conf.d/.

3. Install the FreeType, Fontconfig, and Cairo packages, in that order:

   • From the AUR:

       yay -S freetype2-infinality-remix fontconfig-infinality-remix cairo-infinality-remix
     

   • From GitHub:

     git clone https://github.com/pdeljanov/infinality-remix.git
     
     cd infinality-remix/freetype2-infinality-remix
     makepkg -sci
     
     cd ../fontconfig-infinality-remix
     makepkg -sci
     
     cd ../cairo-infinality-remix
     makepkg -sci
     

4. Ensure your desktop environment's font rendering settings are correct:

   • Anti-aliased font rendering is enabled.
   • RGB sub-pixel rendering is enabled.
   • Slight hinting is highly-recommended.
   • Set your DPI correctly. Use a DPI Calculator to calculate a proper DPI for your system. For single monitor systems, you can let the DPI be auto-detected, but for multi-monitor systems you should set the DPI to that of your primary (or most used) monitor.

5. Logout and back in of your desktop session for changes to take effect immediately.

6. Verify through Xft that non-DE aware applications will use the recommended rendering settings. Run xrdb -query | grep Xft, and your output should be similar to:

   Xft.antialias:  1
   Xft.autohint:   0
   Xft.dpi:        96
   Xft.hinting:    1
   Xft.hintstyle:  hintslight
   Xft.lcdfilter:  lcddefault
   Xft.rgba:       rgb
   

To change these settings, edit /etc/X11/xinit/xinitrc.d/xft-settings.sh for global changes. These settings will be overwritten by your local ~/.Xresources file, so you must remove it, or make sure the settings are the same. This setting only affects X11 applications.

Recommended Fonts

The following fonts are recommended and should be installed for a good experience:

• Caladea (ttf-caladea)
• Carlito (ttf-carlito)
• DejaVu (ttf-dejavu)
• Impallari Cantora (aur/ttf-impallari-cantora)
• Liberation (ttf-liberation)
• Noto (noto-fonts)
• Open Sans (ttf-opensans)
• Overpass (otf-overpass)
• Roboto (ttf-roboto)
• TeX Gyre (tex-gyre-fonts)
• Ubuntu (ttf-ubuntu-font-family)
• Courier Prime (aur/ttf-courier-prime)
• Gelasio (aur/ttf-gelasio-ib)
• Merriweather (aur/ttf-merriweather)
• Source Sans Pro (aur/ttf-source-sans-pro-ibx)
• Signika (aur/ttf-signika)

Optional

The following fonts look excellent, but are not under permissive licenses.

• Consolas
• San Francisco Pro Display/Text

Customization

For more precise font rendering tweaks, edit /etc/X11/xinit/xinitrc.d/infinality-settings.sh.

• The INFINALITY_FT variable may be used to set a preset style. Options are listed within infinality-settings.sh. The ultimate3 setting is recommended, but ultimate5 gives a "macOS" look and pairs well with Apple's San Francisco system font.

• The INFINALITY_FT_* variables may be used to create your own style or tweak the selected preset style.

Changes made here will only apply to new desktop sessions.

Note: It is recommended you test your customizations with a QT or GTK application. See caveats below for more information.

Notable Differences from Infinality Ultimate

• Stem Darkening for TrueType fonts is enabled by default. Only QT-based applications enabled this option resulting in inconsistency with non-QT applications. It is now enabled by default for the ultimate[1-5] styles, for more consistent rendering across applications.
• Autohint is force enabled by default in most circumstances.
• Improved font substitutions using the remix set of FontConfig configuration files. The existing free, ms, and combi sets remain, but remix is the default.

Just Want Infinality?

If you're an Infinality package maintainer and you just want the latest Infinality patch without this remix rubbish, simply apply the 0002-infinality-<VERSION>-<DATE>.patch patch file.

Caveats

1. Chrome, and Chrome-based browsers ship with their own version of FreeType for web content. Only the browser shell (tab bar, address bar, menu, etc.) is rendered with the system's FreeType library. Therefore, only text in the browser shell will look different when using Infinality Remix.
2. There are a lot of potential configuration files that affect font selection and rendering. Ideally you should make your settings as global as possible and remove any redundant user-local configuration files, or at the very least make sure they all agree on the same values, and with your DE. The following list are font configuration files going from user-local to global in scope:
   • ~/.config/fontconfig/fonts.conf
   • ~/.config/fontconfig/conf.d/
   • ~/.xsettingsd
   • ~/.Xresources
   • /etc/fonts/conf.d/local.conf
   • /etc/fonts/conf.d/
   • /etc/X11/xinit/xinitrc.d/xft-settings.sh
   • /etc/X11/xinit/xinitrc.d/infinality-settings.sh
