The current order of preference in fonts.conf causes the Linux desktop to appear as http://bugzilla.ubuntu.com/attachment.cgi?id=3690 when showing Greek. This happens because the current order of preference for fonts places three asian font families high enough, so glyphs from those fonts are shown. Those fonts are not suitable to display modern Greek. There has been a discussion at the fontconfig mailing list, though I cannot reference it due to a bug in the mail archiving. The conclusion was to create a patch to fix the order of preference of the fonts. Patch is included below.
Created attachment 3435 [details] [review] Fix order in preference of fonts, in /etc/fonts/fonts.conf to support Greek The patch 1. adds the MgOpen fonts (MgOpen Canonica for serif, MgOpen Moderna for sans serif). 2. elevates FreeSans/FreeSerif/FreeMono above the asian fonts (CJK) The patch puts MgOpen/FreeFonts just above the asian fonts, so it does not affect other fonts of choice that may be present (such as Bitstream Vera or the MS fonts).
I've applied this patch.
