Title:
  System hangs after connecting or disconnecting external monitor

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Each time I connect or disconnect the external monitor my ubuntu
  system will hang and a Hard reboot is necessary. Only way I manage to
  have the external monitor working is to plug it before booting. Which
  gets quite annoying after a while.

  I had the exact same problem already with ubuntu 12.04 and was hoping
  the upgrade of the system to last release 14.04 would solve it.
  Although it did not. I am using  a vaio vgn-sr19xn with Intel Graphics
  Media Accelerator (GMA) 4500MHD. The external monitor is a Samsung Tv.

  In the wiki says it is a known problem, although I was wondering weather there is some fix for this?
  Which info do you need from me?
