I very regularly complain about the eGPU issue on Linux, since I want to swap so badly–every program I use (with the exception of Drawboard PDF, which operates on a universal standard) is cross platform, and I have successfully installed a wide variety of linux distros on my laptop and got everything working well (even pen input on Xournal!!).
However, I use an Nvidia eGPU to drive three additional monitors I use for work, and on Linux I am unable to hotplug my eGPU, instead requiring a login/logout (or at least me closing all my open programs, which defeats the purpose of hotplug). I’ve tried Wayland/Xorg, and distros varying from Fedora to Pop OS (so far, my best experience was on Kubuntu/Wayland, but the computer still regularly crashed when disconnecting). I wish I were a better programmer, since then I could figure the issue out myself!
As soon as the Linux kernel has better support for hotplugging, I will never need to boot Windows again!
Edit: I am not unfamiliar with Linux, and I’ve been running Linux servers for well over a decade–I just have little experience in the realm of graphics drivers
