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
● bolt.service - Thunderbolt system service

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.

Yep, there is no way to dock it wrong :wink: but it turned out that my systemboard wasn’t working probably and got replaced by lenovo, now the dock works perfectly.
