My question is the same as the title: What is the most secure way to run X in dom0 without GPU?
My computer does not have integrated graphics. My goal is to only use CPU rendering for dom0, so I blacklisted amdgpu in /etc/modprobe.d. When I did that and restarted my computer, it defaulted to only a shell environment. When I tried to run startx, it gave me an error “Fatal server error: (EE) no screens found”.
ChatGPT recommends that I install the xorg-x11-server-Xvfb package, but I read somewhere that it is not recommended to install anything on dom0. Do you think Xvfb could be an exception to this?
I am just asking since I know that VMs can render graphics just fine on CPU, so I don’t see why dom0 can’t render using the CPU either, right?
Sorry for my noobishness.
