Comment 23 for bug 960920

Do you still see the issue without nomodeset and the kernel 3.0.0-19.32 from -proposed? (See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed).

Also, nomodeset should be a not supported configuration with i915 that drives your intel video device, use of i915 implies modesetting always enabled nowadays I expect, only serves for testing.
