We all know running Wayland on KDE while using nvidia drivers does not work. However does the same apply if using Bumblebee?
My understanding is the problem is with the NVIDIA drivers not the hardware so nouveau driver should be ok. Any know for sure???
If you are talking of running Plasma5 on Wayland: it won’t be possible in Leap 42.2 at all as Wayland is not supported nor included, and plasma5-session-wayland is not available either for that reason.
With Bumblebee, the desktop is running on the intel chip though. In principle it should work I suppose, even if you use Bumblebee with the nvidia driver. But I don’t know for sure.
