Luckily, Ubuntu 18.04 LTS is one of them, but it won't install on elementary OS Hera. Here is how I did it.ĪMD only supports a few distros, and only specific versions at that. It takes some courage to install them, but it works flawlessly.

I managed to make Cycles GPU rendering work in Blender by installing the proprietary drivers from AMD. I'm coming from the iGPU (Intel UHD 620) and it feels like I have a new computer. I have no experience whatsoever with eGPU's, and I was up and running in under an hour.įor me, this is a massive leap forward.

hot plugging is not possible, you'll always need to connect your eGPU and do a reboot.If you don't see anything on the external monitor, hit super + p a few times until your monitor lights up. Connect the monitor to the eGPU and make the switch: $ sudo egpu-switcher switch egpu Only after explicitly configuring the internal and external GPU, it started working. I didn't do this initially and things didn't work. When prompted with Would you like to define a specific INTERNAL GPU? (not recommended), confirm with Y. Then to configure your available GPU's, run: $ sudo egpu-switcher config

Let the script generate the necessary files: $ sudo egpu-switcher setup Run boltctl list to get the UUID of the TB device and then authorize it by running sudo boltctl authorize.

Next, connect your eGPU and boot up your laptop. More details about why and how can be found in the troubleshooting section of the egpu-switcher library. In your laptop's BIOS settings, enable pre-Boot ACL in the Thunderbolt settings. Then you can go ahead and run: $ sudo add-apt-repository ppa:hertg/egpu-switcher Enabling PPAs can be done by running: $ sudo apt install software-properties-common To install it, you'll need to be able to add PPAs first, which is not enabled on elementary OS by default (thanks to for pointing that out). It's actively maintained and well supported. You can do this by hand, but it's easy to make mistakes. Next, you'll also need some script to manage GPU switching. It's is shipped by default with Ubuntu, but not with elementary OS: $ sudo apt install bolt Required softwareįirst, you'll need bolt to authorize the Thunderbolt connection. My cables are 2 metres long, plenty to be able to keep the enclosure out of sight (it's huge). To connect the eGPU to the display, a Display Port cable is preferable if your monitor supports DP of course. For the Thunderbolt cable, make sure you buy an active, 40 Gbps TB 3 cable. You won't regret spending the extra buck. A word about cablesĭo yourself a favour and don't try to save on cables. I chose AMD because it works out of the box, no additional drivers required. Finally, the card I'm using is the modest AMD RX 580. For the eGPU enclosure, I went with a Razer Core X, which is ranked as the best option on egpu.io. I'm using a DELL XPS 13 (9370), which has two Thunderbolt 3 ports.
