Core X not connection Lenovo, RTX 2070s

Hello,



I just bought a Core X and a Gigabyte RTX 2070s. My laptop is a Lenovo X1 carbon 6th gen. Unfortunately it isn't plug and play so far.



After some regular updates for the laptop, I enabled something in my bios for thunderbolt.

I managed to install thunderbolt control center and ny I at least van see a mention of the Core X. Which it didn't do with the regular TB3 software I had. If I connect it via TB3, the Core X and the RTX make a loud wind noise, but it stops after a second or two. My laptop is charging thought via the Core x.



Under the device manager, there is however nothing related to the Core X or nvidia. I downloaded the lastest drivers for the RTX (451.67) but I can't install them because there is no nvidia gpu detected.



At a complete loss here what to do.
