Hi,

I'm trying to make (K)Ubuntu work with both, Hybrid and Discrete graphics configs, on my Lenovo P52 (i7-8850H, Nvidia Quadro P3200, 32GB RAM)

First off, whichever config I choose while installing Kubuntu works. If I install with Discrete only, it works. But Hybrid does not work. If I install with Hybrid, Hybrid works but Discrete only not.
As far as I know I need to use the Discrete only config if I want to use the Thunderbolt 3 dock (or its video outputs, to be exact).
But I also need to work with this Laptop while travelling or in Uni, that means I don't have access to a power socket all the time and Discrete only drains the battery very quickly (and makes your upper legs burn!)

What would be the way to go?
I don't have any previous experience with Linux on hybrid configurations, any help is greatly appreciated!
