dmesg log

Hi

I'm having some issue with my GeForce GT 540M card.

The problem is that xrandr doesn't detect my screen when I connect it with
HDMI:
HDMI1 disconnected (normal left inverted right x axis y axis)

But if I manually configure the HDMI device in xorg.conf, I can get video
output on my screen. So that part seems to be working correctly.

But as xrandr doesn't detect my screen, i'm unable to configure dualscreen
correctly.

Attached you can find my dmesg log with drm.debug=0x4.
The last line is when I pulled out the HDMI cable.

I tested the current Ubuntu Quantal kernel, but also the daily kernel, and both
have the issue.

I hope somebody can take a look and fix the issue!
Thanks for all the work on nouveau :)
