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 :)

Can I see your Xorg.0.log please.  Nouveau appears to be detecting your HDMI
display just fine from what I can see.. Not sure yet why X thinks it
doesn't...

Thanks for the quick response.

Attached my Xorg.0.log now.
This is when I booted my system WITHOUT a xorg.conf.
I do get the boot logo on my HDMI screen, but still xrandr doesn't see my
screen.

Also notice something strange in the xrandr output:
HDMI2 disconnected (normal left inverted right x axis y axis)

It now says HDMI2 somehow

When I pull out my HDMI cable, dmesg outputs the following also:

Now I booted my system without HDMI cable in. When I insert the cable after
bootup:

dmesg:

xrandr still:

(notice its HDMI1 again)

Yes, I suspected this was your issue initially and your X log confirms it. 
You're using an Optimus laptop, and the Intel GPU (which is the one X is
using)
is NOT wired up the the HDMI connector.

The boot logo on your screen *is* nouveau's doing, and show's
nouveau's
(mostly, see below) done its job correctly.

If possible in you BIOS setup, you can select "Discrete Graphics" mode
and your
NVIDIA GPU will become the primary adaptor and X should JustWork with the HDMI
display.  But, a great deal of manufacturers don't allow this mode, so it
may
not be available.

Your last resort until X is able to handle Optimus properly (coming up in the
next X server release), is to create an xorg.conf specifying two X screens, one
on the intel (to drive the laptop panel) and another on nouveau (to handle your
external outputs).

This will highly depend on the ordering of which the Intel and Nouveau drivers
load and create the connector objects.

This is expected if the unplug happens while the driver is in the middle of
fetching the EDID.

This is probably a bug in nouveau I'd say, but it deserves a new report.

I'm closing this bug due to it not actually being a bug :)
