A little update on this topic. See below.
• I had to put a second screen on my graphic card (Radeon 9800 Pro)
because after some messages on the screen, they disappeared and left
me with a black screen. With two screens, I could see the machine boot
on the first screen (ADC connector) and then switch to the second
screen (DVI connector) and display the end of the boot messages. This
doesn’t occur with the install media and in didn’t occur in Wheezy nor
Jessie. I need a way to fix this. Any help ?
This doesn't happen anymore with a 9600 card.
• Last : X fails to load. At the end of the boot, the system left me
with a big black screen and a little « —« cursor at the top left of
the screen. display-manager.service failed, living me with an unusable
console and I couldn’t with to another VT.
From ssh on another machine,I’ve tracked the failing service
(lightdm), run Xorg -configure and tried to launch it with the created
config file. I finally could see error messages on my screen and now I
can log in. Here is the message I’ve got when launching X with the
created xorg.conf

I've got the exact same error with this 9600 card. So I've disabled
lightdm.service for now. Any thought ? Is Xorg broken on powerpc for the
moment ?
Also, Is there a way to boot osX with grub now ?
I've got a triple boot install : sid (with grub on /dev/sda2), osX and
wheezy (with yaboot on /dev/sdb2). But I can't boot sid with yaboot and
I can't boot osX with grub. I can't mount my sid ext4 partition in
wheezy either. Are there some new options to the ext4 filesystem enabled
in sid that aren't available in wheezy. Can yaboot access to the kernel
on the sid partition ? .
The grub partition doesn't appear in the apple openfirmware boot screen
(the one you can access pressing the alt key at startup). Is there a
way to have it there ?
I hope someone can finally help me.
Cheers,
Bertrand
