How to use Intel Integrated graphics and NVIDIA GPU at same time on Linux

[thumbtak]

1. List PCI devices

$ lspci

Take note of the bus id of the Intel chip

2. Edit xorg.conf file

Next, we need to edit the xorg.conf file to tell X to use Intel chip by default

sudo mousepad /etc/X11/xorg.conf

Note: Edit  “mousepad” with the editor of your choice.

Copy this in the file but don’t forget to change it with your Bus ID

Section "Device"
Identifier "intel"
Driver "intel"
BusId "PCI:0:2:0"
EndSection

Section "Screen"
Identifier "intel"
Device "intel"
EndSection1

Reboot with the following command:
$ sudo shutdown -r now

3. Test it out

Install the Intel gpu tools if don’t have them already

$ sudo apt-get install intel-gpu-tools

Launch the CPU usage monitoring tool

$ sudo intel_gpu_top

Launch some videos or other GPU intensive app and notice the usage of the Intel chip

Launch nivdia-smi to make sure it’s at zero vram usage

$ nvidia-smi -l 1

You should see something like this:
