Emacs has terrible font handling: there seem to be about three different APIs, and the documentation doesn’t seem to be as clear as it might about which to use. Then there is the additional confusion to do with fonts on X. There are old style fonts that are specified like
and then there are GTK font specifications like
Deja Vu Sans Mono
sometimes with additional
-12 type suffixes.
It’s all terribly confusing. I recently found myself unable to set my font to one that was narrow enough to allow two Emacs windows across one 1280 pixel wide monitor. I posted to Stack Overflow about it, but nobody has come to my aid just yet.
In the meantime, I have adopted a 9pt Lucida Typewriter Sans that looks OK. This does produce a pretty narrow Emacs window, and when I switch to
xmonad, I’ll be able to have two such windows tiling nicely beside each other.
