I am considering to build a new Qubes Workstation for my personal use to play around a little with the
gui-vm. Are there any dedicated GPUs that are more likely to work?
As far as I understand I will only need GPU-passthrough and not the potentially very expensive MxGPU functionality.
Unfortunately I could not find any recent documentation of the Xen Project which video cards are expected to work. The hardware compatibility list of the Citrix Hypervisor lists only expensive Enterprise cards. The Xen-based XCP-ng project however tells that “AMD chips will work perfectly”.
I was considering an entry level AMD Radeon Pro, because they are marketed as “optimized for open source software”, which could make it easier to troubleshoot occuring problems.
Of course I am aware that the gui-vm is work in progress and will require to play around – potentially a whole lot. I am happy for any hints and recommendations that you can make regarding that very experimental feature of Qubes and will absolutely not blame you, if I would have bought something that will not work.
