Hey guys,
Just FYI, I've found a workaround for this issue on 12.04.03 LTS. The fix
involves installing kernel v3.12-rc6 suggested by Christopher. I had wireless
and keyboard issues but they were minor fixes. See details in posts #6 #7:
Tested with kernel 3.11.5 from mailine.

Testing with kernel 3.12.0-031200rc6-generic. Dual monitor now works

occasional GUI lockups (not surprising since Mir is not ready for prime
time yet).

Think this bug may also be affecting me on a second-gen Dell Sputnik
