I am tryihg to follow the wiki on "Fonts in Luatex." It suggests the following statement for Linux systems: export OSFONTDIR="/usr/local/share/fonts;$HOME/.fonts" But I store my fonts in /usr/share/fonts so I used: export OSFONTDIR="/usr/share/fonts" The net effect of this statement was to wipe out all my text fonts used with XFCE4 or KDE, at least when I use my regular user signon. I examined my /etc/profile, $HOME/.profile, @HOME/.bashrc files and deleted or commented out all references to OSFONTDIR. I still have no gui fonts. If anyone has any suggestions on how I can revive my gui fonts that would be welcome. Only my regular user signon is affected, But I really want to know what kind of OSFONTDIR statement I can use that won't wipe out my gui fonts. I can of course move the pertinent fonts to the fonts directories in my /usr/local/texlive etc. file structure. But I am looking for a more general solution.
