I applied the patch to 6.2.10 and it works.
To be able to apply it, I had to adapt slightly (renamed 'mst_output_port' to 'port'). I attached the patch I applied.
Thanks you for working on the issue!

That's great, thanks! So we do have a path to getting this fixed without a revert then, it just might be a few steps.
Can you try to apply that directly to 6.2.y as well to see if it helps there too?

Hi,
6.3-rc6 alone fails the same way. When the commit is added, it works.

And if 6.3-rc6 fails the same way, please one more check with 6.3-rc6

Hi,
Can you by chance cross reference 6.3-rc6? It's quite possible we're missing some other commits to backport at the same time.
Thanks,

I found a regression while updating from 6.2.9 to 6.2.10 (Arch Linux). After upgrading to 6.2.10, my external monitors stopped working (no input) when starting my display manager. My hardware: Lenovo T14s AMD gen 1 Lenovo USB-C Dock Gen 2 40AS (firmware up to date: 13.24) 2 monitors connected via dock and thus via an MST hub
Reverting commit d7b5638bd3374a47f0b038449118b12d8d6e391c fixes the issue.
Best regards, Veronika
