My computer has a graphics card with a DVI port (port 1) and a VGA port (port 2). How can I make the console on Linux display on port 2 instead of port 1? During POST, everything is mirrored on both displays, but as soon as I get to the login: prompt it only outputs on port 1. Yeah, I could probably buy a DVI->VGA adapter, but this seems like something that can be set, maybe in kernel boot params.
