Having stumbled upon this because of the title - "
Linux on a Powermac G4" - well I thought I'd yank the thread back towards the topic.
Seems like this is the state of Linux on a G4 powerpc machine:
For starters, there's
a Facebook group dedicated to this topic. Also,
Executing this search on
https://www.distrowatch.com will show you a list of OSes that will run on powerpc architecture - it's not a complete list, though. Mysteriously they leave Debian off of it.
Based on that, we have:
Ubuntu's probably too intense for the system's resources. Vine is in Japanese.
T2 SDE is definitely its own thing.
I see that powerpc is being "dropped" after April, 2019. I think that's a bit beyond "not supported," because they're "not supporting" ARM7 after the same date... Perhaps the installation media won't be available for download.
Lubuntu already doesn't officially support it, but some mirrors have the installation media images.
There's this link, which is an article about installing Linux on a PPC, particularly with a USB stick
Seems like Ubuntu-based distributions are the most recommended.
Anyways, before I stumbled upon this, I stumbled on a G4 laptop - 867Mhz. I have to use VMs a lot, and I'm familiar with a few lightweight distros of Linux.
I was hoping to find an Arch-based distro, but that seems really dead.
http://archlinuxppc.org is a barren wasteland.
I've always really liked Lubuntu though. I think it's a little heavy for this, but I believe I'll give Trusty Tahr a try.
