I have just installed Debian 8 (Jessie) and with it revived an old PowerPC, which so far has been a very, say, educational but rewarding experience. Unfortunately, my fonts don't seem to work and after searching for hours, I cannot find a solution.
I ran the command
dpkg-reconfigure fontconfig fontconfig-config
which improved the system fonts but did not change the fonts for the menus of the LibreOffice applications or Audacious, for example, although the font renderings of the VLC media player work fine. I am attaching a few screenshots, too.
I am running OpenBox, Xorg, and said Debian on a G4 PowerMac.
PS: this may be of importance but I am also seeing on startup, Failed to start Load Kernel Modules as described here but my system starts fine, so I don't think this is issue is related.
