Warning: Cannot convert string “-*-helvetica-bold-r-normal–14-*-100-100-p-*-iso8859-1” to type FontStruct
This is because some fonts are not available. On Ubuntu use the following commands
- sudo apt-get install xfonts-75dpi
- sudo apt-get install xfonts-100dpi
- xset +fp /usr/share/fonts/X11/75dpi/
- xset +fp /usr/share/fonts/X11/100dpi/
- xset fp rehash
Then reboot.
