Thinkpad Thunderbolt Dock X1 Carbon 6 gen

Hey,

i am trying to connect my Thinkpad X1 Carbon gen. 6 to my new Lenovo Thunderbolt 3 Ultra Dock.
I set in the Bios the Thunderbolt Securitylevel to user and the pre-boot option to disabled.

But it doesn’t show up in boltctl and isn’t working at all:

# boltctl list

boltd is running:

systemctl status -l bolt

But under the gnome Thunderbolt-settings it shows the following:

Any idea how i get it working?

Maybe it is just a stupid question but, did you connect the right port in your PC ? you didn’t connect to the power one right?

If you have it well connected try change security parameters (no security) and check if it is detected.

Regards.
