Hi!

Is it possible to make multiseat configuration on FreeBSD now? Xorg
with VGA arbiter (i've done it some time ago under Linux) or with
bhyve and passtrough PCI devices with VGA/USB cards? Or any other
solution? I need to make second workstation next to my powerfull PC -
i don't want to buy next machine as this has enough power.

Or i am restricted only to remote X/RDP sessions with some kind of
thin client connected by ethernet?

bhyve with pci passthru would work. Get dedicated USB controller to
passthru (so you get usb hotplug, also I don't think there is usb
passthru in bhyve so you need to pass entire usb controller) and
secondary GPU to passthru.

I may be wrong, but I don't think it's possible (yet) to passthru
integrated gpu, I managed to do it on server, but there integrated
gpus are on motherboard, not on cpu.

Also I couldn't passthru some old nvidia quadro (like really old,
2005-2009 era i think). It just didn't work. So your result may vary.

this may help: https://wiki.freebsd.org/bhyve/pci_passthru

Thanks, but on link you've posted there is written:

"Note: VGA / GPU pass-through devices are not currently supported."

Yes, but based on that it worked for me, it's at least worth trying
(if you have spare gpu, or can get one for cheap)
