Title:
  Screen blanks on lid close, never unblank (reboot required)

Status in xorg package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: xserver-xorg-video-intel

  I'm not sure the bug is with xserver-xorg-video-intel, but I'll
  explain why it think it might be.

  I get this issue with the options Blank Screen for When laptop lid is
  closed in AC power in Power-Managent and with Do Nothing and Blank
  screen in Battery Power. Interestingly enough (I think, at least), if
  suspend is chosen, the laptop suspends correctly and brings back the
  screen correctly on resume.

  I tried alt-sys-req to reboot xserver and I tried going to a tty
  (ctrl-alt-f1), but it never brought the screen back on.

  The machine is not crashed and I can ssh to the machine. I used that
  to try a few interesting thing while the screen was blank.

  I found this thread (a bit old, but still):
  http://ubuntuforums.org/showthread.php?t=358432. I tried to "vbetools
  dpms on", but it didn't help.

  https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen has an
  interesting article on intel graphics which I followed. Even though it
  mentioned was marked as a solution for machine lock-up (my machine
  doesn't lock-up per se), I tried the ForcePipeA quirck
  (https://wiki.ubuntu.com/X/Quirks#Force Pipe A Quirk), but when I did,
  Xorg reported that the option did not exist.

  I had a whole bunch of errors in Xorg logs: (EE) FBDEV(0):
  FBIOPUTCMAP: Invalid argument. I looked it up and found no bug reports
  that pointed in the direction of the bug I'm having, so I decided to
  let it be.

  Finally, on one bug report, I found someone talking about installing
  the dbg version of the package, which I did. I played with
  "intel_reg_dumper" a little bit, wrote a bash script that track
  changes to the registers (probably not exactly the most effective
  option, but meh). Basically, what I did is that I ran
  "intel_reg_dumper" before and and after closing the lid (and causing
  the bug). I found somehting, but I don't know what it means...
  VGACNTRL would change from VGACNTRL: 0x22040000 (enabled) to VGACNTRL:
  0x80000000 (disabled). I couldn't find a tool to mess with that
  directly and confirm if it's part of the problem. Most likely it's the
  result of something not being done properly higher up the pipe... but
  I only know that much about the inner workings of linux (very
  limited).
