I can't maker Terminus font the default.

I did the X -configure and added this line under Files in /etc/X11/xorg.conf:
FontPath  "/usr/local/share/fonts/terminus-font/"
Restarted IceWM, restarted Firefox and nothing...terminus does not appear on the list, I also rebooted. What am I doing wrong?
Any app that uses fontconfig (Firefox does) should pick up the bitmap version of Terminus. But Java apps seem to not support bitmap fonts which is why I created the x11-fonts/terminus-ttf port.

Do you have 70-no-bitmaps.conf in /usr/local/etc/fonts/conf.d? It disables all bitmap fonts. If you do you can probably create an exception for Terminus. An example is in Thread 2021.

x11-fonts/terminus-font should be preferred over x11-fonts/terminus-ttf because the TTF version degrades badly and only looks good at certain sizes (see the port's pkg message).
