hi there -
seems, I got no luck installing 16.04. LTS on any of my PPC Platforms.
After failing on G5 PowerMac, I tried to install it on my iBook G4 1.33Ghz 1.5GB RAM ATI 9550 32MB.
Everything is fine, WIFi install works like a charm
BUT every 5-20min GUI freezes (you can move the mouse-pointer, but nothing else responds)
I read, there is an issue with Raedon Cards and I tried the yaboot-params (all of them, one after the other) but same results, GUI freezes after random amount of time…
So, on 12" iBook G4 1.33, MATE seems to be “useless”, same as on PowerMacs G5 with Nivdia Cards…
The website here states: "For G4, G5 Macs, ibook,… " and so on - this should be changed, as only very few models seem to work (I read, that on some powerBooks it does not work, either)
I highly recommend installing “Debian 8 PPC” - but beware, you need to install XFCE and/or MATE Desktop, when asked by the installer - the default Debian one does not work (boots, but you get no GUI)
