I have some questions about eGPUs on Ubuntu 19.04 (with Gnome).

How well do they work?I have a laptop with Thunderbolt 3: with "eGPU box" should I use?

Which work with Linux?Is it better to use Nvidia cards? (I had some bad experiences with AMD card in Linux)

How is the plug and play support? Can I just plug them in while the system is running and use them instandly without rebooting or restarting the X-Server? And can I remove them while the System is running (without rebooting or restarting the X-Server)?

Can I use my internal laptop-screen or does it only work with external screens "directly" plugged into the eGPU?

Thank you very much!
