Bug Description
== Oneiric SRU Justification ==
[Impact]
This wil affect all users of Ivybridge whom use multiple monitors on Oneiric when it releases.
[Justification]
Patch 1 in this series fixes cursor support on external monitors on Ivybridge.
Patch 2 corrects multimonitor bringup. Both only affect ivybridge generation
GPUs and have no chance of regressing other generations. Both commits are
upstream and have been tested internally on 5 different Ivybridge machines to
be sure of correct functionality. They are clean cherry-picks into Oneiric
if that is an easier way of applying.
[Test Case]
Boot the system or hotplug an external monitor. It should work. It doesn't before these changes.
[Regression Potential]
None, the changes are contained to Ivybridge only which are unreleased, and external monitors were not supported previously.

Title: Video is not displayed on external display correctly
Summary: Lost desktop control after conecting system to external display. When first connected to the external display, onboard display disappears and only mouse pointer is seen, and red screen on the external monitor. Pressing Fn + F8 to switch different video out modes doesn't get the desktop back. It's either mouse pointer on the external display or on the onboard display. I have to hard power off the system to restore.
Steps:
1. Install Ubuntu 11.10
2. Connect the system to an external display via VGA or HDMI
3. Press Fn + F8 to switch between different video out mode
Expected results:
First Fn+F8, video signal is mirrored
Second Fn+F8, video signal is extended
Third Fn+F8, video signal is displayed on external monitor only
Fourth Fn+F8, video signal is returned to onboard display
Actual results:
First Fn+F8, onboard desktop disappeared and only mouse pointer is shown.
Second Fn+F8, red screen is shown on external monitor
Third Fn+F8, only mouse pointer is shown on external monitor
Fourh Fn+F8, only mouse pointer is shown on onboard display
