An anonymous reader writes: TechCrunch reports that Dell will be officially re-entering the Linux laptop market. Beginning this fall, it will sell a 'developer edition' of one of its Ultrabooks that comes pre-loaded with Ubuntu 12.04. Dell first started offering computers with Linux installed in 2007, but they dropped the products in 2010. This spring, a skunkworks effort called Project Skunkworks was announced, and now, after the completion of a short beta test, the Ubuntu laptops have been given a green light for commercial sale. Canonical has been working alongside Dell to help make this happen.
