What's your GPU? Did you change any output settings?

> What's your GPU? Did you change any output settings?

My laptop has both an Intel Corporation HD Graphics 620 and an Nvidia GTX 960M. I am using the integrated graphics for the DE.
I also don't remember changing any output settings. 

Note: this only happens on my internal screen. Overview, grid view and cube (view?) also isnt visible on my internal screen.
