I had a chat with Athanasios and we concluded that the GDM themes do come from Ubuntu (and not from upstream GDM), from the packages mentioned in this report.
The clean solution is for the themes to reference the Sans/Serif/etc font aliases instead of individual fonts. I recommend applying this patch. There should be other languages affected, especially those that require extended latin characters that Bitstream Vera does not cater for. -- gdm theme should use dejavu fonts https://launchpad.net/bugs/70829 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
