# Enable GPU for Chrome Linux Enterprise Node

## Prerequisites

A full OpenGL profile requires X to be running. For X to run, it requires a display to be connected to the machine. Given that most server machines do not have this, it becomes difficult to run OpenGL. Google Chrome on Linux will use the GPU if it finds that an external display is attached to the system. This document details how to get OpenGL and X up and running without having a display connected to the server.

**Note**: This instructions uses a g3s.xlarge (4cpu x 30GB RAM + 1 gpu ) instance on AWS

## Get the Machine Ready

### Start by installing the necessary packages:

`yum install mesa-dri-drivers` `yum install -y gcc` `yum install kernel-devel-$(uname -r)` `yum install glx-utils` `yum install libglvnd` `yum install libglvnd-glx` `yum install xorg-x11-server-Xorg` `yum install pkgconfig` `yum install libglvnd-devel`

OR

`$ yum install -y mesa-dri-drivers gcc kernel-devel-$(uname -r) glx-utils libglvnd libglvnd-glx xorg-x11-server-Xorg pkgconfig libglvnd-devel`

### Download and run the NVIDIA installer:

`$ wget 'https://us.download.nvidia.com/tesla/460.32.03/NVIDIA-Linux-x86_64-460.32.03.run` `$ sh ./NVIDIA-Linux-x86_64-460.32.03.run`

## Update Configurations

### Update the grub configuration file to blacklist nouveau:

Open `/etc/default/grub` in an editor.

Amend the `GRUB_CMDLINE_LINUX` to include this blacklist piece - `rdblacklist=nouveau`. The update should look like this:

`GRUB_CMDLINE_LINUX = "rdblacklist=nouveau"`

Re-run GRUB to ensure that the blacklist is in place & reboot the machine: `$ grub2-mkconfig -o /boot/grub2/grub.cfg` `$ init 6`

Upon boot, confirm that nouveau is not installed: `$ lsmod | grep nouveau`

Now run the `nvidia-xconfig` and remove the `xorg` file as its not useful. `$ nvidia-xconfig -a --use-display-device=None --virtual=1280x1024` `$ rm /etc/X11/xorg.conf`

### Enable Chrome Switches

Add/Remove the following Chrome switches and update permissions and owner of the file: `$ vi /var/CatchPoint/Agent/Plugins/Chrome/chrome_custom_launch_switches.config`

Add/Remove the following switches: `REMOVE --disable-renderer-backgrounding` `REMOVE --disable-accelerated-2d-canvas` `REMOVE --disable-accelerated-video-decode` `REMOVE --disable-d3d11` `REMOVE --disable-flash-3d` `REMOVE --disable-flash-stage3d` `REMOVE --disable-gpu`

Update permissions & owner of the file: `$ chmod 0400 /var/CatchPoint/Agent/Plugins/Chrome/chrome_custom_launch_switches.config` `$ chown serveruser:cp /var/CatchPoint/Agent/Plugins/Chrome/chrome_custom_launch_switches.config`

### Start X and restart catchpoint services:

`$ /usr/bin/X :0 &` `$ catchpoint restart`

## Summary

Once X has started successfully, run `echo $DISPLAY`. It is very likely that the output of this will be empty. If you have glewinfo installed, run the following command `env DISPLAY=:0 glewinfo | less`.

The goal of this command is to run `glewinfo` having temporarily set `DISPLAY` to `:0` (virtual display on remote system). If this command runs successfully, you should be able to see the graphics card on the remote system along with the full OpenGL profile. And now you are ready to deploy applications using X.

If you want to set `DISPLAY` for the entire session, run `export DISPLAY=:0`. To set DISPLAY permanently, add the same line to your `bashrc` file.
