uefi boot default max resolution ?

[RolandK]

Hello,

i use proxmox from macbook retina, which has very high display resolution.

i setup uefi vm to check some details of XCP-ng hypervisor, but though i set display resolution to 1024x768 in uefi bios settings of VM (Device Manager -> OVMF Platform Configuration), the linux of XCP-ng boots with a totaly insane high resolution , which makes text hardly readable on the retina display

how can i make it boot with lower resolution (optimally without tuning on the guest/linux side, i just want it that it won't detect display with so high resolution)

thanks

mh. came across this one. but for me , it doesn't even work after using "reset" in efi bios

i'm out of ideas.

setting in grub cmdline to

kern.vt.fb.default_mode=1024x786
or
efi_max_resolution="1024x768"

doesn't have any effect, too. i can't lower the resolution
