On my lenovo laptop it seems I cannot use HDMI when I switch to intel card, I can see the monitor is connected in settings but there is no output signal for it.

Looks like HDMI output associated with nvidia card.

I think external outputs are connected physically to NVIDIA GPU on your laptop. So try with "prime-select nvidia" instead. I've received positive feedback by others, who could use their external outputs by using SUSEPrime in "nvidia" mode.

@sndirsch thanks for the response, yes it works with Nvidia, but the whole idea that I don't want to use nvidia because of heating issues and fan spin noise, this is why I use SUSE prime select.

HDMI is most often than not physically wired to the dGPU, thus handled by the nvidia drivers that you need loaded. There is no other choice if you want working HDMI.

Right. I'm afraid we can't overcome this hardware limitation.
