Try to disable graphics output in bios.
Why do you need a VM? I’m running Scale and other than tinkering with installing a couple VMs I haven’t kept one running. The app catalogs have what I need or a custom container. I only ask because if you don’t absolutely need a VM, then you don’t have a problem, you simply have an annoyance. Without an iGPU capable CPU, you’re already starting yourself off at a disadvantage. You can buy a cheap GPU, like a 710 or some such and use that for the host, or just use what you have for the intended purpose of a NAS with applications.
First; what are you planning to do with it?
Second; how time critical is getting it functioning to you?
Third; I don’t like Ubuntu anything, there are so many other options to pick from that are better, in my opinion. But without knowing what your intentions are, I’ll refrain from recommending any.
Emporia. Fairly reasonably priced for what you get. I have 2 units. Main panel 16 circuit and sub panel 8 circuit.
