Well, I’ll just start by saying this is not off to a good start. I can’t seem to figure out how to get the damn thing going. It’s plugged in and my laptop is connected. The dock is recognized by Fedora
And the GPU is recognized when lspci is entered in terminal
I know I’m running kernel 6.0.7 so that is also checked off. I’m using Wayland instead of X11, which could be part of the problem but since I have no prior experience with eGPUs I have no real understanding of where to look, especially since this is such a new GPU.
Upon rebooting the computer, I am able to get video out to an external display connected to my eGPU but it does not display the login screen, only the BIOS was visible on the external display.
What does these 3 outputs say?
lspci -v |grep -A8 VGA
sudo lspci -vvv
sudo dmesg | grep BAR
EDIT: I think you need kernel 6.1, 6.0 supports Arc mobile if my memory serves.

Phoronix did their testing on 6.0, so mine should support it as well, although I’m slightly behind Phoronix.

When you are outputting from the eGPU, you can’t boot into Fedora is that correct?
If so, that’s expected behavior as Arc will not boot without Above 4G Decoding (not ReBar).
Oh I very much can boot into Fedora, just that the external display won’t show anything. The built-in display is still functional. It looks like I need to change some boot parameters to force the external GPU as the rendering device instead of the iGPU if I am reading this reddit thread correctly
I think an earlier phoronix article said requiring to blacklist.
I am using the 5.17 kernel with Intel’s precompiled drivers, at least for me, the GPU won’t post without “Above 4G Decoding” enabled and CSM disabled.
I am still considering to go to the latest kernel and Mesa on Ubuntu.

Have you tried Fedora Rawhide in your testing? I’m wondering if installing that and getting it fully updated, then rebooting with the eGPU plugged in, would help here.

Thank god almighty, I finally got my A770 to function. I switched to Fedora Rawhide as suggested above to get to kernel 6.2 which removes the experimental flag. It didn’t work at first but after I re-seated the GPU in the enclosure, it was detected and worked fine. I did have to select “dedicated gpu” in heroic launcher and I still got a warning about using unsupported hardware when playing Bioshock 2 remaster but it actually booted into and started playing the game. PROGRESS!!!

I’m glad to hear my suggestion could help! If you’re still on Fedora Rawhide, I believe all those improvements from around Feb have been brought into the stable release of Fedora 38 now, if you wanted to switch.
