# Ubuntu\* 20.04 (focal)

To install the latest general purpose GPU (GPGPU) software packages on 
Ubuntu 20.04 (focal), add the Intel(R) software package repository and 
install the appropriate packages.

## Add package repository

To install the **repositories.intel.com/graphics** package repository, add the
following to your Ubuntu installation. Prior to copy/pasting to your console,
you may want to run `sudo ls` and enter your password to prevent the commands
from being swallowed by the sudo password prompt:

```bash
sudo apt-get install -y gpg-agent wget
wget -qO - https://repositories.intel.com/graphics/intel-graphics.key |
  sudo apt-key add -
sudo apt-add-repository \
  'deb [arch=amd64] https://repositories.intel.com/graphics/ubuntu focal main'
```

The above will make sure your system has gpg-agent and wget installed. It will
then download and install the public key used to verify the integrity
of the package repository. Finally, it adds the
**repositories.intel.com/graphics** repository to the system.

## Install run-time packages

After adding the repository, you can install the GPU software packages by
running the following:

```bash
sudo apt-get update
sudo apt-get install \
  intel-opencl-icd \
  intel-level-zero-gpu level-zero \
  intel-media-va-driver-non-free libmfx1
```

### OPTIONAL: Install developer packages

If you will be doing development, you may want to install optional development
packages. oneAPI users will need to install these packages for some of the
oneAPI tools to function correctly:

```bash
sudo apt-get install \
  libigc-dev \
  intel-igc-cm \
  libigdfcl-dev \
  libigfxcmrt-dev \
  level-zero-dev
```

## Configuring permissions

In order to access GPU capabilities, a user needs to have the correct 
permissions on system. The following will list the group assigned ownership
of the render nodes, and list the groups the active user is a member of:

```bash
stat -c "%G" /dev/dri/render*
groups ${USER}
```

If a group is listed for the render node which isn't listed for the user,
you will need to add the user to the group using gpasswd. In the following,
the active user will be added to the 'render' group and a new shell spawned
with that group active:

```bash
sudo gpasswd -a ${USER} render
newgrp render
```
