On a SuSE 10.2 system – fonts are in:
/usr/share/fonts/
Copy your new fonts into one of the already existing sub-folders depending on type of fonts to be added, then run in consol:
/usr/sbin/fonts-config
To finalize the activation of your newly installed fonts you need to restart your X-server
Ctrl + Alt + backspace will kill the X-Server – after restart the fonts will be available.
