    UPDATE: using Kubuntu 12.04.1 LTS.

    Community supported until April 2015. So far so good.

    Messing with my PowerBook, in 2 days, i managed how to get sound and Airport Extreme to work. Later i got the PMU (power management) working.

    I self-compiled and tested Linux 3.6.0-rc4 kernel (not-ubuntu) and the PMU stopped working. After that i run apt-get upgrade and got an update to the 3.2 kernel, which was somewhat better and stable.

    I'm thinking to write a guide...

    Re: Where to download Ubuntu for PowerPC and other frequently asked questions

    Hi folks,

    Lubuntu is still committed to ppc, as are the people who make things like the kernel happen:


    As of when the next rebuild happens [1] the kernel for ppc should now boot okay. This has been tested with servers (G3 & G5) only and how it behaves with the multitude of graphics cards apple shipped with their machines is an unknown. Below is the chat I had:


    (22:55:56) phillw: xxxxx: do you know if linux-ppc [powerpc] (saucy-proposed) [3.11.0-0.1] is the kernel that will get ppc desktops back working?
    (22:56:11) xxxxx: phillw: Should do, yes.
    (22:56:27) xxxxx: phillw: I just smoketested it on my G3 and G5, and both work.
    (22:56:57) phillw: great, so the cron build tomorrow should put the ppc-lubuntu testers back in the chase?
    (22:57:45) xxxxx: phillw: Depending on how quickly I get it migrated, but probably yes.
    (22:58:38) phillw: xxxxx: scheduled to start at 16:29 (UTC) is that enough time for you?
    (22:59:22) phillw: or would you prefer an extra 24 hours?
    (23:00:43) xxxxx: Oh, indeed, it's almost a day until the next build. Yeah, that one should be fine.
    (23:01:31) phillw: xxxxx: okies, if you are sure, I will email the testers, obviously they are chomping on the bit to get back to work!
    (23:02:43) xxxxx: I make no guarantees that various DRM/KMS drivers are working (I don't run consoles on any of my PPC machines, they're all servers), but these kernels at least boot on all my kit, which is a step up from the previous version.
    (23:03:05) phillw: there's one sure fire way to check
    (23:03:27) xxxxx: 3.11 includes a pretty massive changeset to the radeon driver, so that could cut both ways. Maybe it's drastically improved, or maybe it has a ton of new bugs that break it on !x86... We'll see.
    (23:04:55) phillw: as always, we rely on the testers to let us know That the promise to have a kernel that at least stood a chance of working has been kept, they will be happy and do not 'rant' over bugs.
    (23:05:42) xxxxx: Well, I can nearly guarantee that it should boot on pretty much any hardware we've supported before. Between yyy and I, we have a pretty wide array of stuff to boot and stress test on.
    (23:05:49) xxxxx: It's just that he and I both only run headless servers.
    (23:05:51) xxxxx: So, we'll see.
    (23:07:07) phillw: the graphics cards that apple used were and are always an issue... they have gotten used to workarounds, only by letting it into the wild can these issues with the graphics cards be started to be investigated
    (23:07:38) phillw: xxxxx: many thanks to you and yyy for this work, I do know ppc for desktops is a low priority
    (23:07:42) xxxxx: It's not the cards, per se, it's that the radeon driver has become very x86-centric, and very few people care about fixing the PPC bugs with it.
    (23:08:09) xxxxx: nouveau seems to suffer fewer of those issues (for whatever reason), so the nvidia cards that Apple shipped with later G5s seem to be in better shape.
    (23:09:35) phillw: we're still working with G3's and g4's... as long as the darn thing will boot, the graphics cards could be seen as nearly a seperate branch of their own.
    (23:10:19) xxxxx: Yeah, I haven't tried running X on the ATi Rage128 in my G3 for, like, a decade.
    (23:10:38) xxxxx: I assume it probably sort of works. But I have no idea, and don't care, as it's a headless router/firewall in my house.
    (23:11:14) xxxxx: Though, the offb driver would work for boring old 2D X. You'd just get zero acceleration.


    So, allow the daily to build and start testing!!! [2]


    Regards,


    Phill.

    Nice to see there may be hope for an old Mac I have, it's a G4 but with an aftermarket graphics card. May have to revisit that if I get this current project stable.

    Re: Where to download Ubuntu for PowerPC and other frequently asked questions

    I was successful in installing Lubuntu 13.10 ppc to my Powerbook G4 12" 667mhz, 256mb ram, nvidia geforce fx go 5200. I encountered no problems loading the desktop live cd and running the installation.
    However, there are several problems encountered after the installation.
    The wifi does not work and I had to install b43 firmware and restart.
    I am unable to watch youtube videos in firefox so I had to download and use minitube instead.
    No sounds are coming out of the laptop. Still looking for solutions.
    Function keys are not working so I cannot adjust brightness, volume, etc. Still looking for solutions, especially to the brightness issue.
    Battery applet would not load to the panel, although I can see my battery charge status in system profiler and benchmark. Just a minor issue.

    Re: Where to download Ubuntu for PowerPC and other frequently asked questions

    Hello,

    I've experienced the same sound issue as you've mentioned on my 12" Powerbook G4 and have tried every single stop from the FAQ (mainly deleting the snd-aoa entries from the blacklist), but nothing works out for me. Have tried Debian 7 in parallel and here sound works great. Do you have any positive news on your list of open points?

    There seems to be a crash in the snd_powermac module during start-up:
