MSI GP66 Ubuntu Drivers Problem

Hey, I’m trying to install ubuntu on my laptop: MSI Vector GP66 12U – Born for Performance. After system and drivers instalation have a issue about that only External monitors are working(NVIDIA(Performance Mode)) or laptop display(NVIDIA On-Demand). I was trying many ways to fix this but no progress, could you help me with this issue?
