I have problems with loader console on SOL and on Proxmox. On an old DELL R610 SOL (ttyb) isn't working any more and on Proxmox I have dark grey letters on black background. To check if this has something to do with Graphical Console setting, can I disable graphical Console in loader.conf (or friends)?

ttyb is not working any more - how so?

it was working before?
