I have a brand new X1 Extreme Gen 2 which rund Ubuntu 19.10. I also bought the Thunderbold 3 Workstation dock. However, the dock display out is not used in hybrid or intel mode It works only in pure Nvidia mode.
I already tried around a lot, installed bumblebee, latest nvidia driver and so on. Connecting the HDMI monitor directly to the notebook does not help, too. The notebook seems to mention a display been connected. On Kubuntu, there always came a pop up whch asked which onitor to use. But regardless what I choose the external monitor does not get a signal. On Gnome/Ubuntu, nothing like this seems to happen.
It's an older LG model 24" with HFMI and DVI ports.
Also tried this tool which sounds very interesting, but...
sudo intel-virtual-output No VIRTUAL outputs on "
Maybe it's worth to dig deeper here?
BIOS-settings: TB ecurity off, secure boot off, any Microsoft reated stuff off.

On Windows hybrid mode is not working correctly, at least not with an external display. It becomes very laggy, see https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-extreme-screen-lag-on-quot-second-screen-o...
