I had recently installed Ubuntu on my Sager Notebook Computer , and I noticed after a while that there was a LOT of screen tearing on my PC. I started researching the topic and found a lot of solutions. The first thing I tried was installing nvidia drivers using
sudo apt-get install nvidia-current
This did not fix my problem.
I then tried to change the settings in Nvidia X Server Settings, but it said that "PRIME Displays cannot be controlled by nvidia-settings and must be configured by an external RandR capable tool. The display is shown in the layout window for information purposes only"

I then tried to install CompizConfig and change the refresh rate to >144 Hertz, but that also did not effect anything.
After some more research I tried to use the xrandr command to change the refresh rate, but that also had no effect.
I tried to disable Wayland and enable GDM3, yet that also yielded no change.
I then tried installing Bumblebee in hopes of fixing the sync, but that had no effect, and even Soft-Bricked my computer later.
