[Infrastructure] Does running this project requires GPU (external / non integrated)?

[luckyAkbar]

Describe the bug
I tried to run ConvertX on my machine, but got error message related to VGA support. Because I didn't see warning / requirement section for infrastructure, I wonder does running this project requires GPU (external / non integrated)?

Hmmmm maybe calibre has some option to disable vulkan?

Hmmmm maybe calibre has some option to disable vulkan?

I don't have deep knowledge about the internal working of calibre, but do you think by finding option that relates to GPU utilization by calibre and maybe tweaking that can possibly solve the problem? If yes, I'll try to do that

I run it on second gen i7 with integrated graphics and it's fine
