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: sudo apt-get install -y gpg-agent wget wget -qO - https://repositories.intel.com/graphics/intel-graphics.key | sudo gpg --dearmor --output /usr/share/keyrings/intel-graphics.gpg echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/intel-graphics.gpg] https://repositories.intel.com/graphics/ubuntu jammy legacy' | \ sudo tee /etc/apt/sources.list.d/intel.gpu.jammy.list Step 2 Install run-time packages: You can install the GPU software packages by running the following: sudo apt-get update sudo apt-get install \ intel-opencl-icd \ intel-level-zero-gpu level-zero \ intel-media-va-driver-non-free libmfx1 libmfxgen1 libvpl2 Step 3 Install developer packages: sudo apt-get install -y \ libigc-dev \ intel-igc-cm \ libigdfcl-dev \ libigfxcmrt-dev \ level-zero-dev Step 4 Configuring permissions for render: To access GPU capabilities, a user needs to have the correct permissions. The following will list the group assigned ownership of the render nodes, and list the groups the active user is a member of: stat -c "%G" /dev/dri/render* --> render alin@alin-cmcm2fb:~$ stat -c "%G" /dev/dri/render* render groups ${USER} alin@alin-cmcm2fb:~$ groups ${USER} alin : alin adm cdrom sudo dip plugdev lpadmin sambashare My user doesn't have access because is not part of 'render' Now we add my user (alin) to group (render) sudo gpasswd -a ${USER} render alin@alin-cmcm2fb:~$ sudo gpasswd -a ${USER} render Adding user alin to group render newgrp render verify: groups ${USER} alin@alin-cmcm2fb:~$ groups ${USER} alin : alin adm cdrom sudo dip plugdev render lpadmin sambashare Now we see user is part of render.
