Anyone got a Radeon X800 AGP working on Linux?

I recently got a Mac flashed one, the open firmware prompt works as well as MorphOS runs perfectly on it!

The problem is on the linux side (Ubuntu MATE 16.04 beta2). My PowerMac7,3 freezes as soon as the desktop is reached and I only get a garbled screen. The boot-process however is shown correctly in the console. Anyone got some advice on the boot parameters?

So far I tried "video=ofonly radeon.agpmode=-1" and "video=offb:off radeon.agpmode=-1" as boot parameters but had no success.

You may need a properly configured xorg.conf file.

We ran in to this problem with the newer Amiga NG powerPC machines.
Without the proper xorg.conf in place everything froze.
The solution was to install a base Ubuntu-Mate 16.04 with the alternate installer
then copy the xorg.conf then install the Desktop .
A problem developed after with the updated alternate installer not finding hard drives so this became an issue.
The solution was to create an .img files of a base installation with the xorg.conf for each machine in /etc/X11. user just copied the right one to xorg.conf then installed the Desktop.

Later solution was to create a complete .img with the Desktop installed for the various machines and graphics card options. .img can be booted from USB and copied to hard drive .

I've read that that card isn't supported by Linux.

It is supposed to be .

It should work with Linux , but probably not flashed one.

I have only bad experiments with flashed cards and especially flashed cards with Linux.

Only flashed card I have got working at all was some Radeon 9800. It worked fine with OSX, but it did not work with Linux after of-mode was changed to Radeon one. I did not try it with MorphOS.

Hmm, interesting! Thanks for the hint.

But this really looks just like a bog standard xorg.conf without any special options. Will try that on weekend and see what happens. Luckily the Gentoo Linux PPC CD just boots into console mode, so I hope I can just copy this xorg.conf over without installing everything again.

Relatively Standard. It works on 3/4 machines tested . Sam460ex,X5000 and Tabor .
The X1000 needs one of two different configurations depending on Northern Island or Southern Islands card.
Ubuntu 16.04 is very picky about the xorg.conf or lack of with powerpc so if it doesn't work at first try a few modified xorg.confs before you give up on the video card.
