Morphos Developer Bigfoot is working on a way to boot MorphOS with an X5000 dual graphics setup.
More info:
https://morph.zone/modules/newbb_plus/v ... 03&forum=3
(as posted by Bigfoot)
Long story short, if you have a single graphics card in the primary (x16) PCI Express slot that works for you in all the operating systems you want to run, then there was no problem. If you're in a situation where you want to use two different graphics cards for two different operating systems, or even just one graphics card in a PCI Express slot that's not the x16 slot, then you're out of luck, at least until MorphOS 3.17 gets released..
On the MorphOS side, I fixed a few different issues that prevented MorphOS from booting with a graphics card in a non-primary PCI Express slot on the X5000, thus enabling you to, well, boot MorphOS with two graphics cards installed. And no, before anyone asks, using 3 graphics cards in the X5000 won't work with MorphOS
Looking forward to MorphOS 3.17 ...

Yeah...
01.05.22 - Public Release of MorphOS 3.17
Tweaked the PCI address mapping on the X5000 to accommodate a Radeon on the PCIE1 bus
Hope it works... keep you posted!

Hi Dave ,
Can you please help with a working xorg.config for dual graphics cards on an X5000. (Radeon Rx550 and Radeon HD6450)
Cant get anything working with the newer kernel .(After Kernel 4.19.325) and that only works with Ubuntu 16.04
Thanks
Regards
Julian

Thanks for the xorg.config .
Managed to get Adelie to boot . Will try some other flavors .
Still cant get Ubuntu Mate 16.04 to boot with new kernels and the dual card config.
Also cut and paste of the xorg.config from your email and from your original post seemed to bring
some unseen incompatible charters into the xorg.config file so had to retype from scratch.
Well worth the effort of course .
