Public bug reported:
This bug occurs with 3.2.0-32-generic. I'm on a Dell E6510 with
integrated Intel Graphics running 12.04LTS. System
Settings->Details->Graphics says Iten Ironlake Mobile.
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
