I had a fresh install of Ubuntu 12.04 on my Alienware M11x, and it worked with the native monitor resolution of 1366x768. In trying to get the Optimus chipset working, I installed Bumblebee 3.0. Now, I am only offered 640x480 for my monitor resolution. Graphically, Unity 3D appears to be working now, instead of the Unity 2D I had before, so something went right, but I don't know how I can get it to offer me any higher resolutions than 640x480.

I've looked up many pages that address this topic, but nothing that I've seen suggested has worked.

sudo add-apt-repository ppa:bumblebee/stable sudo apt-get update sudo apt-get install bumblebee-nvidia

was the latest thing I tried. I've tried some variants of this, I've been sure to uninstall nvidia drivers prior to reinstalling Bumblebee and various video drivers.

Does anyone have any clue as to how I can get back to native resolution?
