    Mac Pro 2013 (6,1) 24.04 - GPU issues

    Hi all,

    I'm not sure how to resolve this issue. Most distros seem to have an issue with the D300/500/700 GPUs in the 2013 Mac Pro - most of the time I have to use nomodeset to get into the desktop at all. A while back I found one distro that - to my surprise - worked (Fedora 39). I would like to try out Ubuntu 24.04 but I'm back at the same issue as before requiring software rendering. I'm not sure what is different. I've tried forcing the use of the amdgpu built in driver via grub - no success. lshw shows the GPUs as unclaimed.

    On Fedora 39, this is what I see:



    and inxi shows:

    I'd really love to give Ubuntu 24.04 a try - although I like Fedora, honestly Ubuntu is still like an old friend and I'd love to be able to get it to work on this hardware - plus I'd really like an LTS on this antique if at all possible... Any tips on where I can look to find whatever magical setting in F39 is making the GPUs functional so I can try it in U24.04?

    Were you able to resolve the GPU issue? I will be doing a build with repurposing my 2013 Mac Pro with D500s to make a Nextcloud server.

    Good luck.

    I have issues too with a repurpose MacPro 2013 AMD D300, the video works fine, but the audio is horrible. Worked fine until a an update, just can't figure out when it when bad...

    What I believe may be causing your issues is a probability that your machine could most likely have both an integrated GPU and a discrete GPU and the drivers might be conflicting with each other.
