Re: Debian 8 on Late 2005 G5, Graphics Issues
Hi Peter,
I get it. What you describe is in the plans — and thanks very much for the detailed directions; it’s pretty much what I had planned to do myself, but it’s always nice to have confirmation. Actually, even better, I plan to re-install with stock-out-of-the-box Jessie plus your tweaked kernel. The only reason I had Sid installed at all was my search for a working nouveau.
The reason for the previous test was because it was easy to do and I (mis-)interpreted you as wanting to know how that particular combination worked out in my case. Sorry for the noise!
Now that we have a working theory as to why nouveau fails, I’m happy to use a supported stable (Jessie) system with a slightly tweaked kernel — rather than an avowedly unstable setup with a stock kernel that doesn’t have a prayer of working.
In the long run, somebody (with better kernel coding skills than me) needs to fix the nouveau driver to work with 64K pagesize. However, I suspect that will be considerably harder than configuring the current kernel to use 4K pagesize, as a short-term workaround.
I’ll definitely report on how things work on my hardware with your kernel, but it will have to wait til after the weekend. 4th of July == US Independence Day == lots of neighborhood/family/etc parties and celebrations == no time for playing with computers.
I’m looking forward to sending a report soon!
Rick

Make sure you re-enable nouveau by taking it off the blacklist and only add modules "snd-aoa-i2sbus" and "i2c-powermac" to /etc/modules. This should get audio along with windfarm running. Update your initrd by running "update-initramfs -u".
