I have bought ASUS ROG GL502VY and it comes with one GPU (Nvidia GeFroce gtx980m 8GB VRAM), I tried installing ubuntu on it, and I succeeded but!
first problem is it only detect 4k display settings and by default it has no 1920x1080 resolution to set, after installing nvidia driver I get nvidia x server settings, when I set resolution on 1920x1080 it zooms into 1/4 of my display and not scale it all.
second problem is that it does not recognize anything related to monitor and graphic, I can't adjust brightness, I can't lower resolution(even after manually add it using xrandr)
Is there anyway to get my laptop working with ubuntu without the Intel GPU and only with installed Nvidia or I should just give up!?
