Hi,

I've got a Dell XPS 13 9370 and am looking into maybe getting an eGPU that I would use as a dock with one or two external displays plugged into the eGPU. After doing some research I think the Gigabyte RX 580 Gaming Box might be a good choice, but I'm a bit afraid of it because I've seen some users here who had bad experience with AMD eGPUs in the past. However most of those posts are very old by now, and the situation (to my knowledge) should have been greatly improved with the latest kernel versions.

Has anyone got the RX 580 working in a Thunderbolt 3 enclosure on Linux yet? Is it worth trying?

Hi Timur,  I am concerned with your comment:  'I've seen some users here who had bad experience with AMD eGPUs in the past. "  Can you please clarify? 
AMD XConnect is fully supported on PCs, and it does work very well with Dell XPS laptops.

Regarding Linux:  not Intel, nor AMD or NVIDIA officially support eGFX on Linux, so your eGPU experience is not guaranteed and definitely will not be the same as on Windows 10.

Yeah, sure:

Not sure what AMD XConnect is.

I'm not interested in "official" support, and am willing to tweak stuff to get it working. Just looking for people who had already tried an RX 580 in an eGPU on Linux and can confirm that it works for them.

Sorry if the question was unclear but I thought I asked it in the Linux forum - I don't use Windows.

Hi Timur,

Did you get your XPS 13 working with an AMD egpu? I've been looking at the sonnet puck ( https://www.sonnettech.com/product/egfx-breakaway-puck.html) or similar with the same hardware as you (XPS 9370) but I haven't seen anyone getting an egpu with an AMD card to work well under linux. 

Cheers!

Since you don't have a dGPU, the eGPU should be recognized easily. Just plug in and authorize the Thunderbolt device. For getting display and graphics acceleration see the threads on x configs.

Edit: Nevermind, looks like the issues from this thread may or may not extend to the XPS 9370.
