After the tram-smash that is font display in Fedora I had to revert back. O'Suzy (as some call it) isn't *perfect* but it is quite usable. I still can't get Sabayon to install, but I think I know the reason now, and will take steps to sort that when the replacement HD arrives.
I don't know what the reason is: it's not KDE vs Gnome, because I did a full KDE dual desktop install, switching back and forth (you acquire a HUGE range of different applications that way - more than any Windows user could possible have and keep their machine running happily). It's also not the graphics driver, because both Fedora and SUSE are running the Noveaux OSS driver. And it's not the fonts themselves, because I changed the system fonts around from their default settings in Fed, and what worked at one size would then bleed yellow or blue in a different size.
I'm done with pUbuntu and related OSs for now. It's a real shame, but they just cannot seem to get that one fundamental requirement right.
Wonder when Sabayon 5.5 is out.....
