Help:MathML in Linux

The primary problem with using MathML in Linux is installing the correct fonts and getting the web browser to use them. Mozilla browsers (non-Firefox) will use the fonts once available. Firefox has other issues that must be dealt with. The following web pages deal with these issues:
 * Fonts for MathML-enabled Mozilla
 * Notes on MathML

In the case of Debian Linux, MathML rendering can be gotten to work using the following steps:
 * Install both of the following Debian packages, which contain fonts used by Mozilla in rendering MathML characters:
 * latex-xft-fonts
 * ttf-opensymbol
 * For Firefox, you need to disable Pango by creating a file called "rc" in your "~/.mozilla/firefox" directory that contains the following text, with NO spaces: MOZ_DISABLE_PANGO=1

There may be a few more issues, but this should be a good start. See the previous links, particularly "Notes on MathML" for non-Debian based Linux systems.
