Re: Currently stuck with PowerMac G5, NVIDIA GeForce 6800.

Just following up, my solution was to completely give up on the NVidia card and purchase a ATI Radeon 9600. After installing firmware-linux-nonfree, it managed to boot without having to add any kernel parameters, and the glxgears program even runs. Strange thing is that my Apple CinemaDisplay that worked with the NVidia card doesn't work with the ATI card, but thankfully I had success with a more modern monitor.

I am trying to get this system to work with Debian. When I run lspci the video card is identified as:

VGA compatible controller: NVIDIA Corporation NV40 [GeForce 6800 Ultra] {rev a1}

I currently have a fresh install of Jessie with the MATE desktop. I was able to successfully boot to the DE using the nouveau.modeset=0 yaboot parameter, but the desktop has abnormal psychedelic colors.

I did some googling and found the page at Power PC Liberation (http://powerpcliberation.blogspot.com/2016/02/g5-nouveau-3d-acceleration.html) which led me to Peter's post (https://lists.debian.org/debian-powerpc/2016/02/msg00025.html) and I followed all instructions. Thank you for the kernel, Peter!

However, unfortunately, after rebooting to the "test" yaboot option, I don't get a login prompt any more. Instead I get an empty gray screen. Are there any next steps that anyone can recommend? I can still boot to the abnormally-colored DE using kernel 3.16 using the "Linux" yaboot option. Thanks in advance for any guidance you can give me.
