[Joseph Salisbury <joseph.salisbury@xxxxxxxxxxxxx>]

Thanks for the additional info.  The 3.8.0-19-generic #29-Ubuntu kernel
is fairly old and was based off the upstream 3.8.8 kernel.  The latest
13.04 kernel in -updates is 3.8.0-31.  You would probably hit this bug
if you applied the latest updates on the 13.04 system.

We now know the bug did not exist in upstream 3.8.8, but it does in
3.8.13.2.  We need to narrow it down further to know the last good  3.8
version and first bad.  Can you test the following kernel:

3.8.9: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.9-raring/
3.8.11: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.11-raring/
3.8.13: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13-raring/

Title:
  video switch hot key will return "super key and p" and no response to
  switch video mode

Status in “linux” package in Ubuntu:
  In Progress

Bug description:
  CID 201209-11735

  For some machines, for example, HP laptop "HP 1000" has a hot key on F4 to perform the shorcut "super + p" to switch video modes.
  Use command "sudo showkey -k" to capture the key code of the hot key you will see the key code of "super key" and "p"
  This key combination is expected to change the video mode.

  
  platfrom: HP laptop "HP 1000"
  image: 12.04.3

  Steps to reproduce:
  1. open an terminal, 
  2. plugin an external monitor
  3. press the video switch hotkey, for "HP 1000" it is the F4 key

  Expected result:
  1. Video mode is changed by the hotkey
  2. no character is printed on terminal

  Actual result
  1. Video mode is not changed.
  2. a "p" will be printed on the terminal screen

  The other information:
  1. A similar bug was reported on LP:#539477 before.
  2. The hotkey in 13.04 works
