this seems like a very basic question, but after searching the web for 2 hours I couldn't find any real help on the subject and it's driving me nuts.
It's brutally simple: I have a radeon 4670 video card (rv770xt), use Arch Linux' repo kernel and have monitors on VGA and DVI. KMS is enabled and doing fine.
The VGA monitor has a smaller resolution than the DVI monitor and by default the screen is mirrored to both with the VGA monitor's resolution. Now I don't want to use the VGA monitor at all for the kernel framebuffer/console and want the kernel to use the (bigger) DVI monitor.
Note: This is not about X.org dual-head, it's about the kernel framebuffer/console.
Now here's the question: Are there kernel parameters to specify a default output for my framebuffer and if so, which?
The best way to do that I have found so far seems to use con2fb on startup to move all the VTs to the 2nd monitor, but I don't even know if the radeon driver creates 2 fbs and it would only be a workaround anyways.
Edit1: I checked, the driver just creates fb0, so
con2fb is a no-go
