I'm trying to install the font from http://font.gohu.eu/ on 12.04. It recommends the pcf font but when I install it, I do not see it in any applications (gvim, gnome-terminal, gnome-tweak-tool). I tried the ttf as well but it still didn't work. I haven't had problems with this font installing before.
You should have a look at this, it should work with other pcf fonts too.
You'll probably just have to open a Text Editor, put in he following content
save it as .fonts.conf in your home directory and run
Update: For me, it only worked, when using
How are you attempting to install it? Did you double click the TTF, then "Install Font"? If so, did it seem to install without issue? Can you find the font in any of the folders where fonts are usually placed? (See "Fonts" on the Ubuntu Wiki). If you can't find the font there, try moving it there manually.
