Hmm, often with these kind of blank-on-X-startup bugs it is because your
video is getting sent to the wrong output device.

Unfortunately I can't tell from your logs which output devices you have,
but usually you test this by adding something like this to xorg.conf:

Section "Monitor"

    *

      Identifier "LVDS"
      Option "Ignore" "True" 

EndSection

Usually you can see what output devices are available by running
'xrandr'; this also indicates which is turned on.  You may be able to
locate this info in your dmesg.

Please try starting up in the failed configuration, then ssh in and
collect the following:

  * `dmesg > dmesg.txt`
  * `sudo dmidecode > dmi.txt`
  * `DISPLAY=:0 xrandr --verbose > xrandr.txt`

Then attach those three files.  Also if you find that by switching off
one of the outputs solves the issue, let us know that too and we may be
able to put in a quirk for your hardware.
