Just installed MintPPC 11 on my iMac G5 1.8 GHz 20 inch. Everything works out of the box.

Sound does not work out of the box. I added the following extra kernel modules in /etc/modules:

Code:

snd_aoa_i2sbus
snd_aoa_fabric_layout
snd_aoa_codec_tas
snd_aoa_codec_onyx

Sounds like the next machine on the list to get the conversion. How much ram does your machine have in it?

I have 1 GB memory in this machine. The machine works very well with MintPPC 11.

Does your iMac has an ATI vidcard?

Mine is an iMac G5 17" (iSight) but I can not enable 3D acceleration.

As noted here ( https://help.ubuntu.com/community/RadeonDriver ); problem seems to be:

Code:

Make sure your OpenGL renderer string does not say "software rasterizer" because that would mean you have no 3D hardware acceleration.

It actually does say "software rasterizer" and I don't know how to fix it ;(

I have an nVidia card which works with the Nouveau driver. I don't use 3D and I know nothing about it, sorry.

EDIT:
Recently I was not successful anymore getting Nouveau to work with this video card. I had to go back to nv. As nv has a bug for this particular machine, I compiled a patched version:

Thanks to str8bs, I can now enjoy nouveau again, to do this there are two options of which the second one is permanent:

1. Via boot: command option:

Code:

boot: nouveau.noaccel=1

2. Edit (nano) /etc/modprobe.d/nouveau.conf to include:

Code:

options nouveau noaccel=1

Edit: the only drawback to this is that I can't watch DVD's or watch minitube with this setting, this only works with acceleration enabled. This is not a solution for me, so I revert back to nv...

Confirmed same minitube drawback on mine.

May be another work around which I can't explain why... other than maybe it resets VRAM?
I am using DVI-I-2 at 1280x1024. Boot up to the tiling/corrupt lower half of screen issue. (using nouveau with no xorg.conf)
1. Open terminal and run:

Code:

xrandr --output DVI-I-2 --mode 1024x768 --panning 1024x768

2. And then put it right back where it was:

Code:

xrandr --output DVI-I-2 --mode 1280x1024 --panning 1280x1024

This gets me back to my desired resolution without the original issue.

The same without the --panning option does NOT solve the issue. Maybe resources/video memory are being reserved for "off screen" elements and setting panning to actual size prevents that?

ok, final soultion with nouveau, use the following xorg.conf file and you are out of trouble:

Code:

##only difference is Virtual entry in this one is square "Virtual 1680 1680" instead of display actual size 1680 1050

To be honest, after playing a couple of days with nouveau on my machine, I went back to nv. Browsing, which I do mostly on this machine, works best with nv. It's a whole lot faster with nv as compared to nouveau. I can live with a little bit less support for video. This is my final conclusion.
