Is it possible to use an egpu with built in laptop screen?


I’ve been trying to get my egpu working with my laptop screen. Through multiple try, my latest result was that i got nothing display at all.

The screen turns black after the boot process, where sddm suppose to be display

My previous attempts:

So I just wanna ask if it is possible to use a egpu to display to laptop built in screen

If it is then what step/guide i need to look into, and will it worth it?

I think a priori it is possible, but you need to have versions of drivers for everything that don’t lead to a segfault…

If you can start and observe multiple GPUs (like it works with iGPU+dGPU in laptops), then xrandr offload could work, hopefully.
