Bug Description
This bug occurs with 3.2.0-32-generic. I'm on a Dell E6510 with integrated Intel Graphics running 12.04LTS. System Settings-
It does NOT occur with 3.2.0-31-generic.
After booting, the laptop display goes blank, external displays work correctly.
If I add nomodeset to the GRUB boot line, the laptop display will work (booting into 3.2.0-32) but external display support is limited a single display and the resolution of the laptop display. The Display control panel shows that only the Laptop display is active even though it is being displayed on an external monitor (the laptop lid is closed).
Please let me know what other debugging information is needed.
Thanks
Dan
