Hello everyone,
I have just bought an Asus F556U laptop with an Intel Core i7 CPU and a Nvidia Geforce 920M GPU. I installed Manjaro on it.
Manjaro comes with a software called "bumblebee" and I can't really understand what it does from the Arch Linux Wiki. I don't even know whether I need it or not.
I see when I press F3 in the videogame Minecraft it says it is using a Intel HD Graphics 520 (Skylake GT2). In Manjaro Hardware Detection I see video-hybrid-intel-nouveau-bumblebee is installed. I tried to uninstall it, and choose Nouveau or Nvidia proprietary drivers instead, but Xorg won't start with that config.

Something else I would like to know is how to disable Vsync. With an AMD R7 graphics card I could do it and I saw from the Arch Wiki, but I don't really know how to do it with Nvidia.

You might have the situation where the Nvidia card would output *via* the Intel video card.

I would advise against uninstalling such packages, unless you're quite willing to break xorg and hence not have a GUI.

For vsync on Intel, check out TearFree and vblank_mode.

optirun or primusrun mincraft will allow it to use the discrete GPU.
