Title:
  screen lock disables dual monitor

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Hi,

  I installed 12.04 from cd so no upgrade this time but clean
  installation but I kept my old home patition with new installation.
  This is first time that I did not have to install nvidia propietary
  driver after installation or upgrade which is amazing and all my
  thumbs up for this. Also my dual monitor is perfectly autotedected at
  start up and working great out of the box. There is just one problem
  and it is when my creen os locked up due to my inactivity, when I
  unlock it I loose external monitor. I can open monitor settings and
  try to detect monitors but external monitor does not show up. What I
  have to do is to unplud externam monitor from laptop and plug back in.
  Then it automatically re-setup  dual screen as it dooes at start up.

  Just to mention my laptop is Macbook Pro 7.1.

  Thanks for great improvement regarding dual displays.
