Power Mac G5 black screen

I came to this thread:

https://lists.debian.org/debian-powerpc/2015/12/msg00041.html

while having problems with my recent install of Debian on a Power Mac G5

This model http://www.everymac.com/systems/apple/powermac_g5/specs/powermac_g5_dual_2.0.html

I followed the instructions but can’t seem to get the computer to boot into a proper graphical UI.

I’m able to see most of the boot process but then ends in a black screen. I’ve followed various other threads and once was able to see the Debian desktop but the colors were all psychedelic. I’m able to ssh in with no problem.

Any help you might have would be much appreciated. This is my first time trying linux on the PowerPC. My wife wanted me to junk it but its a piece of art in my eye!

Here’s my /boot dir

I’ve pointed the initrd.img and vmlinux to the two new files

here’s my yaboot.conf (confirmed that I ran ybin -v afterwards)

(You can see that I’ve been playing around with append but commented it out in this edit
