Default monospace font

[Gordon Messmer]

I see that I missed the discussion of the default font change, already, 
and quite the pity.  I vastly prefer Luxi to DejaVu, especially the 
monospace font.  DejaVu is just a little bit hideous.

What's the easiest way to change the preferred fonts?  I tried moving 
Luxi Mono to the top of the "prefer" list in 
/etc/fonts/conf.d/60-latin.conf, but Thunderbird and gnome-terminal both 
seem to still be using DejaVu.  I'd prefer not to have to change the 
font in multiple places if I don't have to. :)
