Ok, now let's start a _real_ discussion, not only kindergarten manifestations of omnipotence.
After this deluding fake, I would like to understand were the problems are to get Gentoo running on the new iMac G5.

So, I hope here we can have a serious discussion on:
- What the kernel lacks and what's there: what does prevent Gentoo from running?
- What hardware is there and what is unsupported
- Any important base package that won't compile.
- Will the PPC(32) livecd boot?

As for the hw:
- NVIDIA GeForce FX 5200: i don't think the drivers are there for PPC64.
- Serial ATA hd : I never had a SATA, is there a problem installing on it?
- Network card : anyone knows if there is a kernel module for this? I can't find the exact model.
- Firewire, DVD/CDRW, USB... : should already work, I think

Weeell, here on Italy I'll be one of the first to have it 8), next week. Have I really to stuck with Mac OS X (which isn't bad, only it's not as free as speech)?

Thanks for any help.

SATA drives work like a charm
the nic card should be

modprobe sungem

try that

should work.

There are mosty certainly no nVidia drivers available for ppc64 at this time.

I have been STRUGGLING to get X.org compiled on my 2 x 1.8GHz (7,3) PowerMac G5. It keeps failing when it tries to find 'libGLU.so.1' even though I have set '-opengl' in my USE flags.

Argh!

Otherwise, I have a great system up and running 2004.3 beta with little to no problems, which would be perfect if I were just trying to build a server, but unfortunately I want a desktop machine!

This site had all the info I needed to boot my system:

http://dev.gentoo.org/~tgall/

All I need now is a GUI and I'd be happy. ARGH!!

:)

yes... compiling xorg-x11 is currently broken with 2004.3 profile.

here is what you can do:
a) switch from linux26-headers to linux-headers; compile xorg-x11; switch from linux-headers back to linux26-headers.
b) download this package: xorg-x11-6.8.0-r1.tbz2 and move it /usr/portage/packages/All/. Do an "emerge xorg-x11 --usepkg" and be happy ;-). (you have to add "=x11/base/xorg-x11-6.8.0-r1 ~ppc64" to /etc/portage/package.keywords")

I would like to see a comment in bugzilla about success/failure of running 6.8.0, so that I can mark it stable.

You won't burn your CPU if the thermal control does not work; you will have to put up instead with fans going full speed all of them (pretty loud if I were to judge according to the behaviour of my G5). As far as I know thermal control for the iMac G5 is said to be in the works and available real soon now.

I will try this. Here's hoping to success. Xorg has been the only blocker in considering my G5 gentoo installation a 'success'. :)

Success!!

Method b worked. I have Xorg running now. Awesome! Now I can move onto installing KDE.

What bug is this in bugzilla so that I might find it and comment? :)

Thank you very much.

That comment is enough! ^_^

I marked xorg-x11-6.8.0-r3 stable. binary package for users using linux26-headers is on the way. ;-)

By the way, to answer this question I ran into the same problems with xorg-6.7.0.

Apparently we have a workaround now, tho. Praise be to the heavens!

I also followed the link and used method 'b' to install xorg. However I am not sure how to configure X. I have a new apple 20" cinema display and Radeon 9600XT graphics card.

My previous experience with gentoo install (on 800mHz G4 ibook) I was able to use an autoconfiguration program to get X working, so I am not sure how to proceed. I tried using xorgconfig but I am not sure how to find the values for HorizSync and VertRefresh values for this monitor. Apple's "technical information" on the website as well as the monitor's "manual" seem to be devoid of any helpfull information except for dimensions and how much the monitor weighs. Attempting to google for the answer also didn't lead me anywhere.

I am able to see a fullscreen X-server from OSX, so I know it can't be that difficult to set up. I know that a working configuration file is hidden somewhere is OSX but can't seem to find it.

If anyone can lead me in the right direction I would really appreciate it.

So... I bought my iMac G5 yesterday, thought I'd install Gentoo, first try gave me some windtunnel testing and a stalled computer. Checked out tgall's PPC64 page, downloaded the experimental iMac G5 gentoo ISO, ran it up and typed in the iMac kernel command (you know.. the loader prompt).
The whole screen got blue stripes on it (vertical ones) and i can hardly see what's happening. Any Ideas?

The iMac has:
1,8 GHz G5 proc.
GeForce FX 5200 Ultra graphics
Regular Eth (no airport or bluetooth)
Standrad Mac USB keyboar + mouse

What's happening? Is this usual?

it's a known bug, there's also a patch proposed in the bugzilla... i've been trying to tell it devs by any possible mean without success....

personally i would use PPC32 instead of PPC64 since you have more software for that platform (after all even OS X is 32 bit, right?), anyway even PPC32 LiveCD uses an unsupported kernel, so no way to install gentoo... at least i couldn't get it installed so far.... i really would like to hear from some dev about this topic.... anyone listening?

I'm a bit disappointed i must say that as of today Yellowdog 4.0.1 is capable of running on imac g5.... (still no audio or thermal control) I understand it's PPC32, not PPC64 but i don't think that is a big issue.... Gentoo is not there... and I can't understand who i should contact even to try helping for what i can....

I really hope some dev reads this post and tells us what we all can do to help... I even hope that by chance 2005.0 will be bootable on iMacs... both PPC32 or PPC64 would be great-.... we just need a LiveCD including a patched kernel....
