Check the font path with command xset q
.
You can change the font path with command xset fp= <comma separated set of strings>
(notice the blank after “=”). Suitable directories to be added are usually located at /usr/share/X11/fonts and /usr/share/fonts, e.g.:
xset fp= /usr/share/fonts/default/ghostscript/,/usr/share/fonts/default/Type1/,/usr/share/fonts/liberation/,built-ins
(Warning: any invalid item would make the whole command fail).
“built-ins” fonts aren’t in any directory, they stay in the display server itself.
To start with the needed font path already set, consider editing of /usr/NX/etc/node.cfg in this way:
DisplayServerExtraOptions "-fp /usr/share/fonts/default/ghostscript/,/usr/share/fonts/default/Type1/,/usr/share/fonts/liberation/,built-ins"
