This class of bug occurs because the video is being directed to the wrong output device. Unfortunately, the logs captured by the bug tool are not indicating which output that is, so I can't give specific directions, but here's what you need to do.

First, determine what outputs you have and what state they're in, by logging in remotely and running 'DISPLAY=:0 xrandr'. It might be a TV, HDMI, VGA, or other output shown as on, when you know nothing is connected to it.

Next, edit your xorg.conf and force the phantom output off. In section "Section "Device"" add the line:

    Option "monitor-LVDS" "LVDS"

Then the following new section:

    Section "Monitor"
            Identifier "LVDS"
            Option "Ignore" "True"
      EndSection

Replace "LVDS" with the name of your invalid output device.

If that solves it, we can quirk your hardware, but we need add some additional info:

  * `sudo dmesg > dmesg.txt`
  * `sudo dmidecode > dmi.txt`
  * `xrandr --verbose > xrandr.txt`

Then attach all three of those files.

I have reported [Bug 391870] [NEW] Need DVI quirk for [8086:2a42], and
I don't see blank screen a lot after 2.6.31 kernel. So please close
this bug. Many thanks!
