I really love your work on PowerPC, very informative and I appreciate the technical details, which go back since your earlier work of PowerPC Sunset series! It would be really useful if you could do a little tutorial detailing: - which distro are you using (preferably with downloadable links); - the supplemental steps one needs to follow to get the distro installed (since the default installation is problematic); - which drivers are currently usable to get GPU acceleration (again, links would be highly appreciated); - whether a xorg.conf file is needed and if so, which are the recommended parameters for the supported Apple GPU cards on late 2005 PowerMacs, since this is one of them you are using (Nvidia 6600/Quadro or ATi X1900). Thank you for your contribution to the PowerPC community!
Hi 2009svr, I'm glad you enjoy my content. You may be in for a treat. I am not going to do a step-by-step tutorial with links for two key reasons: 1. Links go obsolete fast. 2. Overall steps may change. HOWEVER I'm planning a series to cover alternatives to the mainstream OS and distros, from a perspective of usability, privacy and stability, x86 and non-x86. To support this work, I am developing a scoring system to rank operating systems. I'll not make a full step by step tutorial but, as part of the reviews, I will cover the key installation steps. Linux is complicated. Each PowerPC distro I've tested breaks in a different way. But I plan to cover the general knowledge that can get you through any hurdles with PPC Linux: basic open firmware wizardry, getting grub manually installed and calling your kernel directly from the open firmware prompt if required. Stay tuned. =)
Very interesting information, I almost forgot the earlier PowerMac G5 models had AGP, all I saw in videos was PCI-e, it makes complete sense though, the first PowerMac G5 was in 2003 if I remember correctly, which is around the same time as HP zx6000, which also has AGP.
Yup. Only the latest G5 is PCIe. Now, cool thing though - I tried Adelie Linux and there are no graphics corruption on the older nvidias. It's an incredibly smooth and light distro. However, there are not many pre-built packages and I didn't manage to get a build environment ready on it. The documentation is pretty scarce.
There are endianness issues. I have a Quadro P1000. The screen is totally distorted once you load a desktop environment, and the text console has a blue background. I'm actually in touch with someone from the nouveau team to see if we can sort it out.
Feels like GPU acceleration is broken. Is the renderer llvmpipe? If so, the (already weak) G5 is doing the GPU's work on rendering interfaces, which goes as well as you might imagine, like what happens when you drag windows. Honestly getting GPU acceleration out of a NV 6600 might be more pain than it's worth, but I'm not aware if any card you can put on the G5 has proper support on Linux.
I think it's more due to lack of support to big endian. This GPU should be enough to render a window as texture and drag its contents around. TenFourFox runs ok even in new web pages, plus this desktop environment is not the best. Most probably the browser is doing software render. There are some AMDs that I could test, but then the computer wouldn't run Mac OS. I am now daily driving a SGI workstation and will get back to the G5 later, running this time FreeBSD on PPC. So far, though, the bad internet performance makes it a good candidate for a daily driver. I can still check the internet for references, but I am not tempted by it.

you can now install modern video cards like quadro p4000 in linux and with the pcie you can use amd or nvidia actually
