Context
I’ve just received my framework laptop 12th gen and I’m very happy with it. I installed Fedora first, everything was fine, then I tried Manjaro, it was ok.
Problem
For both of those distros I could not plug my external monitor with a proper thunderbolt cable through the USB-C port of my laptop to the thunderbolt 3 port of my monitor. If I plug it, I can hear a connecting sound, then a disconnecting sound, over and over and over.
Logs
When I run dmesg -w
just to observe what’s happening here, I can see this:

Question
Do you guys have any idea of what’s happening here ? I think it may be a firmware issue. Video output through HDMI is working fine, but I need to use my computer closed and connected to an external display with thunderbolt

The screen I’m currently using: https://www.lg.com/us/monitors/lg-38wn95c-w-ultrawide-monitor
Both of the distros where up-to-date
Hope you could help me !
