Jae-hyeon Park, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  [GM45] xrandr does not enable external display after suspend/resume
  cycle

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  An external monitor is connected to the VGA port of my Thinkpad X200
  Tablet laptop.  Before the laptop is suspended, I can give an xrandr
  command to set up a dual-head configuration.  After resuming from a
  suspend, xrandr does not turn on the external display even though it
  seems to arrange the outputs logically within the virtual screen.  The
  external display starts to work if I switch to a text console by CTRL-
  ALT-F1 and then back to X by CTRL-ALT-F7.  This problem can cause
  window managers such as mutter and compiz to crash if the screen
  configuration gets changed while they are running.

  
  How to reproduce:

  
  $ xrandr
  Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192
  LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm
     1280x800       60.0*+
     1024x768       60.0  
     800x600        60.3     56.2  
     640x480        59.9  
  VGA1 connected (normal left inverted right x axis y axis)
     1280x1024      60.0 +   75.0  
     1024x768       75.1     60.0  
     800x600        75.0     60.3  
     640x480        75.0     60.0  
     720x400        70.1  
  HDMI1 disconnected (normal left inverted right x axis y axis)
  DP1 disconnected (normal left inverted right x axis y axis)
  HDMI2 disconnected (normal left inverted right x axis y axis)
  DP2 disconnected (normal left inverted right x axis y axis)
  DP3 disconnected (normal left inverted right x axis y axis)
  $ xrandr --output LVDS1 --mode 1280x800 --panning 0x0 --output VGA1 --mode 1280x1024 --above LVDS1  # at this point, VGA1 is turned on normally
  $ xrandr --output VGA1 --off --output LVDS1 --mode 1280x800 --panning 0x0  # back to single-head configuration
  $ sudo pm-suspend  # laptop is suspended and resumed
  $ xrandr --output LVDS1 --mode 1280x800 --panning 0x0 --output VGA1 --mode 1280x1024 --above LVDS1  # now VGA1 is not turned on; one needs to switch to a text console and back to X to enable VGA1
