Fool you once, shame on it. Fool you twice, shame on you. Fool you a third time, what the forget is wrong with you. 
Also I opt for XFCE when I deal with Linux.

It originally had Leopard (I have no loving clue how my dad got it on there since the G4s do not disc drives that read dual-layer discs...) and it was slow as forget so my dad told me to format the whole thing and throw 10.2 on it (the original OS that came with it). Then, since that OS was so old and unsupported, I upgraded it to Panther (10.3), which had problems with downloads (DMG files would always show up corrupted for no reason). My dad just said forget it, put Leopard back on there.
But how would we do it?
Used the Firewire utility on my mom's macbook and connected the two machines together. Installed Leopard onto the G4 through her Macbook. Mission accomplished (once it finishes installing).
ANYWAY, back to Linux.
I upgraded to 10.10 to toy around with it on a partition.
As far as I can tell, Maverick is working fine. Maybe it's just liveCD/USBs that it hates?
EDIT: Yes, it's definitely just the LiveCD/USB it hates. I just tested 10.10 on a thumb drive, then CD... Both were miserable wrecks. If you want 10.10, INSTALL IT!
Also, updated poll with more shells for Linux
