I recently bough a supermicro c246 chipset motherboard with built in BMC graphics. My processor is i3-8100 with built in igd. I am trying to use the intel graphics for GVT-g but i would like proxmox to display the console only using the BMC graphics so if something goes wrong i can use iKVM. Currently, proxmox chooses igd as primary display after bootloader thus i loose the ability see anything though iKVM. It works fine, if i blacklist intel igd but I loose the ability to do GVT-g.
