randr resolution setting, using nouveau

Hi all,

I've set up a dualhead screen configuration using the nouveau driver. I know that nouveau is unstable, I just want to know if the following behaviour is because of nouveau, or because I'm not able to write a proper xorg.conf file.

The Problem: The screen resolution is too low on my second screen (VGA). However it is correct on my primary (DVI). When I use the commands

xrandr --output DVI-I-1 --mode 1920x1080 --primary                                                                                                
xrandr --output VGA-1 --mode 1680x1050 --rotate left --left-of DVI-I-1

after logging in, the resolution is just fine.

I just don't know, why the resolution settings fail initially.

Here's my xorg.conf -- note that it doen't matter if I uncomment the "virtual" setting.

I'd be happy if someone could clarify this for me.
