cat <<EOF > ~/.config/fontconfig/fonts.conf
<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>

2. Post-Install Checklist

Application Installation & Setup

System Configuration (Performance)

  • fstab: Remove discard option from SSD mount points.
  • Swappiness: Set vm.swappiness=10 or 5.
