Since pve v5, I've struggled with getting a usable video resolution on the proxmox console. Especially with servers that have VGA output, proxmox tends to default to the highest possibly supported resolution, often leaving the KVM or rack-mounted-VGA out of range.
Up to this point, I've been able to use the following GRUB settings to force to a lower resolution.
However, I've added a couple of NUCs to my lab cluster, and I want to use their iGPU. NoModeSet breaks GVT, which takes me back to unsupported resolutions. It's frustrating to watch the machine boot. It respects the 800x600 till about 3/4ths of the way through the boot, then changes to an unsupported resolution.
So... what's the RIGHT way to force 800x600 without breaking GPU acceleration?

doesn't work -- investigate EFIFB?
