What is going on here with this class of blank-screen bug is that your
video card is connecting two of its video outputs, and sending the video
signal to the wrong one; this is why the system seems to be otherwise
working (login sound, etc):

(II) intel(0):   Output VGA is connected to pipe none
(II) intel(0):   Output LVDS is connected to pipe B
(II) intel(0):   Output TMDS-1 is connected to pipe A
(II) intel(0):   Output TV is connected to pipe none

Test if forcing the undesired output off solves the problem.  To do
this, try explicitly disabling TMDS-1 (or LVDS) in your
/etc/X11/xorg.conf:

In section "Section "Device"" add the line:

     Option "monitor-TMDS-1" "TMDS-1"

Then the following new section:

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

If that works, then please attach the following:

  * Paste in the output of lspci -vvnn | grep -A1 "VGA compat"
  * Run sudo dmidecode > dmi.txt and attach dmi.txt to the bug report
  * Give the laptop model name and number 

Also, please attach files separately, NOT in tarballs, as that adds
extra steps to processing your bug report.
