emgd Xorg output from successful DVI launch

using meta-intel commit 902d2f3c919cd1d870dc8d35a7521cbba42e53ea with poky/master commit 6c2b7beac3cd23ed44bd3e195c6360a0932876bf, I got successful DVI output after changing the PortOrder Option from 40000 to 24000:

   Option     "ALL/1/General/PortOrder"      "24000"

Attached the xorg.conf I used and the Xorg.0.output from the successful boot into sato.

I'll try to compare with the failure output and see if I can spot any differences.

One thing it would make sense to do in any case would be to change the PortOrder as above i.e. basically try DVI output first, then LVDS.

I don't see the Xorg log from the failure.

But the xorg.conf is different - not sure why you're using a different one from the version from the BSP.  Can you try the attached xorg.conf that worked for me?

I tried with your xorg.conf, and the DVI output is now drived but the resolution is not rightly detected. and the monitor displays "signal not supported".

Here the output of xrandr :

root@crownbay:~# DISPLAY=:0 xrandr 
xrandr: Failed to get size of gamma for output default

   640x480        75.0     72.0     70.0     60.0  

It's now better than previously, where resolutions were those of the lvds output.
I set the native resolution of my screen (1280x1024@60) and now the display is correct.
I attached my correct Xorg.conf

The problem I encountered now, it that mouse and keyboard are not working. I don't know if it's a xorg.conf configuration problem or a kernel/udev misconfiguration

PS/2 keyboard and mouse work here, but USB keyboard and mouse do not.  Looking into it...

More information on my USB mouse/keyboard problem.
Kernel detects usb input correctly.

I tried to fix the mouse and keyboard configuration in my xorg.conf file and add these lines :

Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
EndSection

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "auto"
        Option      "Device" "/dev/input/mice"
        Option      "ZAxisMapping" "4 5 6 7"
EndSection

Section "ServerLayout"
    Identifier     "Default Layout"
    Screen 0       "Screen0" 0 0
    InputDevice    "Mouse0" "CorePointer"
    InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

What i get in the Xorg.0.log is : 
[353919.071] (II) LoadModule: "mouse"

This is really strange, it's like the xorg drivers wer not compiled with the same xorg server ?

I build the same angstrom/oe-core config for MACHINE="beagleboard" and x input modules are correctly detected.

Hmm, your changes actually work for me - usb mouse and kbd now work, but in my case the same lines in Xorg.0.log shows the xserver is 1.9.3.

Could it be you're building the wrong version of the xserver in your build?  Seems like it shouldn't happen because of the line in the crownbay.conf:

PREFERRED_VERSION_xserver-xf86-dri-lite ?= "1.9.3"

With the latest meta-intel and poky, and the PortOrder change in place, I'm no longer seeing any problem with USB mouse/kb, and everything else seems to be working ok as well.  I'll post the PortOrder patch - please try it and verify it allows the DVI output to show up.  If you're still seeing other problems, it would probably be best to file a new bug for those.
