[TUTORIAL] Installing official NVIDIA driver in Optimus laptop

[TiGER511]

1. Why four processes are shown with the command nvidia-smi ?

two /usr/lib/xorg/Xorg and two /usr/bin/gnome-shell ?

2. Is there a way to switch from the Intel chip to the Nvidia chip (not necessarily dynamically)? I personally tried bumblebee but I couldn't get the Nvidia module unloaded.

3. Are there any configurations to apply to reduce GPU power consumption in portable mode?

Thx

1) There is always duplicate xorg adn gnome-shell process in nvidia-smi .I myself is looking for an explanation of this.

2) If you install nvidia driver driver by this tutorial,it wil always use nvidia chip.If you want to use intel chip later on without uninstalling nvidia,i think it is possible,but it will be a lot of hassle.

3) To reduce power consumption ,you can turn off Nvidia GPU altogther with ACPI.
