    I’m running with egpu hooked up to a laptop with another Nvidia card built in.

    Hey could you please point me to some resources to wrap my head around what I need to know to consider an egpu setup with Linux? Just looking for something that will overview of requirements and pain points, all the better if I can try to figure out what a good bang for the buck rig looks like right now.

    This is something I’ve been curious about for awhile, but most of the articles I’ve found seem to assume I’ve got some egpu knowhow already.

      I found almost no resources for this but it was mostly plug and play.

      One thing I can suggest is keep everything same brand. My laptop has an Nvidia gpu built in and I tried using amd gpu without success. Spent about a week on it and tried various combination of drivers and settings. Nvidia just works.

      Also Intel gpus require rebar enabled which almost none of the laptops support so I did not really consider them even though they were super attractive because of pricing.

      The way I use it is set prime-select to Intel2 which disables built in Nvidia gpu and then I activate external gpu after login by running nvidia-smi as root after login. Then you just launch apps you want to use Nvidia gpu with

      __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia command_name arguments

        Thank you! So it sounds like I just need to find a GPU and enclosure combo that fits my budget (TBD) , and it’s like adding any other bit of hardware. I do have an intel-only system currently (integrated Iris XE), so I’ll have to dig in on that. Thanks!
