Font configuration (Slackware) ------------------------------ This package does not modify system font configuration. To make Iosevka the default monospace font for applications that request the generic "monospace" family (for example terminal emulators, Geany, Firefox
 blocks, Dillo, or pekwm menus),
create the file:

  ~/.config/fontconfig/fonts.conf

with the contents:

  
  
  
    
      monospace
      
        Iosevka Term
        Iosevka
      
    
  

Iosevka Term uses terminal-optimized spacing and is preferred here;
plain Iosevka is listed as a fallback. The change takes effect the
next time each application is started (reopen your terminal, Geany,
Firefox, etc.).

This allows applications to use Iosevka without hardcoding font
names in individual programs.
