Using NGC containersĬontainers provide an easy way to set up your development environment. If you see the process /usr/lib/xorg/Xorg, it means that your X session is now being accelerated by the NVIDIA GPU. There may be other GPUs displayed, depending on how many NVIDIA GPUs your system has. The results should display the utilization of at least one GPU, the one in your eGPU enclosure. nvidia-smi showing that the X server is running on the NVIDIA eGPU with other usage metrics. Reboot and check to make sure that your X session is accelerated by the NVIDIA GPU by looking at the output of $nvidia-smi.

Revert /etc/default/grub to the default by removing “3” from GRUB_CMDLINE_LINUX_DEFAULT and update grub: $ sudo update-grub

Reboot into runlevel 3 and check whether the NVIDIA proprietary driver is loaded: $ nvidia-smiĮdit /usr/share/X11//nf to add an additional option in OutputClass to allow the NVIDIA X driver to accelerate X instead of it being driven by the integrated GPU: Section "OutputClass" Lastly, update grub and restart: $ sudo update-grub GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

# For full documentation of the options in this file, see: # Uncomment the line below to force the login screen to use XorgĪfterwards, boot into runlevel 3 by appending 3 to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub: #If you change this file, run 'update-grub' afterwards to update # See /usr/share/gdm/gdm.schemas for a list of available options.

For Ubuntu 20.04, this toolkit is available from the standard repository: $ sudo apt-get install nvidia-cuda-toolkit Offloading Xorg to the eGPUĪfter installing the NVIDIA proprietary driver, make sure that gdm3 (the graphical login manager) for Ubuntu 18.04/20.04 doesn’t use Wayland by commenting out #WaylandEnable=false in /etc/gdm3/nf: # GDM configuration storage Get the latest version of the NVIDIA CUDA Toolkit for your distribution. You must also stop the kernel from loading Nouveau.

Because Nouveau doesn’t support eGPU setups, install the NVIDIA CUDA and NVIDIA drivers instead. The existing driver is most likely Nouveau, an open-source driver for NVIDIA GPUs. Make sure that the NVIDIA GPU is detected by the system and a suitable driver is loaded: $ lspci | grep -i “nvidia” Update the system to the latest kernel: $ sudo apt-get update Install Ubuntu with the eGPU connected and reboot. This post assumes that you are going to be using Ubuntu 18.04 LTS/20.04 LTS. Some considerations are power consumption, card size, GPU memory, and clock speed. Your choice of GPU depends on your use case and choice of enclosure. My enclosure of choice is the Sonnet eGFX Breakaway Box(350W). While enclosures vary in features, size, power delivery, and cost, the folks at eGPU.io also maintain a list of Thunderbolt 3 enclosures with a succinct description of their features to help you make your decision. The laptop that I’m using is the Lenovo ThinkPad X1 Yoga(4th Gen) running Ubuntu 20.04 LTS, but this post has been tested to work on Ubuntu 18.04 LTS as well. This post focuses on eGPUs on Ubuntu Linux. The folks over at eGPU.io maintain a list of the best laptops for eGPU applications.ĮGPUs are supported on Windows and Linux. Laptop manufacturers can design laptops with fewer than four lanes though, so you should consult the laptop manufacturer to find out how many PCIe lanes are available using Thunderbolt 3 on your machine. Thunderbolt 3 is a hardware interface that works over USB-C and supports up to four PCI Express (PCIe) lanes between the host CPU and devices such as GPUs, which gives you a theoretical maximum: 4 x 8Gbps (the bandwidth of a single PCIe Gen3 lane) = 32 Gbps Making sure that your laptop supports Thunderbolt 3 The performance of an eGPU solution depends largely on the performance of the GPU, performance of the CPU, and connection bandwidth between the two. With a single Thunderbolt 3 cable, I can connect my laptop to a powerful, dedicated GPU multiple monitors and peripherals. Most enclosures provide all of these, so all you need to use them is a laptop with Thunderbolt 3.īecause I value the portability of a thin and light laptop but want the raw horsepower of a dedicated GPU to get serious work done, eGPUs allow me to get the best of both worlds.
