egpu-switcher VS osc

If you're ok with running X11, you can use egpu-switcher and modify the Xorg configuration yourself afterwards.

Only using Xorg since Wayland gave me more issues than fixes. I'm using egpu-switcher

Try installing eGPU-switcher, make sure you have the right drivers installed, and as others have said make sure you have the right cable. Last thing, only plug in or unplug the eGPU when the laptop is off.

You didn't mention the problems you ran into but it should be plug and play. You will have to set up the proper config for it to work properly, and I would recommend using hertg's egpu-switcher if you are having issues: https://github.com/hertg/egpu-switcher

I've been using egpu-switcher every single time.

The scripts are all-ways-egpu for Wayland and egpu-switcher for X11.

here is the hotplug script that seemed promising, but did not work for me (nVIDIA only) here is a more sophisticated-looking script that seems intended for Desktop-users though, and also specifically excludes hotplugging options...

It is not plug&play, but almost. https://github.com/hertg/egpu-switcher

The A750 is now a recognized PCIe device, and works with connected displays to an extent. During boot, KMS/Plymouth shows on connected displays, as well as GDM (albeit, laggy, but it did that before anyways). The problem starts with Xorg, where during startx, I get a No screens found error. My Xorg configuration was autogenerated by egpu-switcher, where it only fails in egpu mode (connected displays do not work in internal mode). GNOME on Wayland works surprisingly with my laptop display working as normal, but the eGPU's external displays come with various graphical glitches, stuttering, outputting to 1080i30 on a 1440p60 display, etc.

https://openbuildservice.org/ is one way to produce distribution packages across a wide selection of distributions, if your source code is open.

As fair as I understand, OBS is indeed a suitable replacement for AUR right now.

OpenBuildService is better in every way, is fully opensource everywhere and can even generate packages for ubuntu better than launchpad appears to, and can even build entire distros. No special integrations are necessary, it can cost-effectively work with a highly paralellized number of virtual machines (iinm 100 or more on generic threadripper or epyc).

Suse's OBS is another option, and there are likely others...

Good idea, give it a try. I'd recommend Kubuntu or Mint with Cinnamon. I switched to KDE for KDE Connects' amazing smartphone (Android) integration, which i recommend srrongly to try. Switched to openSUSE Tumbleweed myself, best KDE implemention IMHO, rolling release and the software selection is great, whats missing from the repos can be installed via opi, a client for [0]. It is not that newbie friendly though, since SUSEs' focus is on the enterprise ie safety over ease of use.

Try it on openSUSE, the best KDE integration by far IMHO, since it is their standard DE since IDK/forever? Tumbleweed offers the newest packages, rolling like Arch, but with a huge test battery on OBS (https://openbuildservice.org/). Snapshots on upgrade make the thought of breakage (haven't had any) tolerable.
