I have installed the esstix fonts for kformula and I really need esstixeight. Unfortunately this is one of several that kformula can't use for some reason. Infact kcharselect shows Helvetica or something when looking at esstix8. I downloaded with Konqueror and then tried with wget. I followed the instructions from the help file. I tried manually installing by copying and fc-cache -f 'ing.
I saw something during googling about a problem with fontconfig and those fonts. I am going nuts because I am trying to make things look right in my lab reports, but I would rather not use MS Office every time just to put brackets around a fraction! Does anybody have these fonts working in the current gentoo set up? What have I got to do to get these things in? Btw, I also tried logging in as root and running through the same deal to no avail.
