Proxmox (legacy bios) unable to change screen mode

1

Howdy,

I noticed in my Haiku VM running on Proxmox (legacy bios and virtio_gpu) that when I try to change anything under Screen I get “The screen mode could not be set: Unknown mode”.

Is this a current known issue?

You would have to check the bugtracker for that :slight_smile:

Though atleast for me it is not known.

Yes, it is a known issue with the virtio_gpu driver in Haiku. There is a ticket in Trac about it: https://dev.haiku-os.org/ticket/19176
