While many people and companies are jumping on the Linux bandwagon these days, it is important to remember that Dell has long been a proponent of the open source kernel. It has offered Ubuntu on some of its computers -- a gutsy move being such a major Microsoft partner. It may not seem major these days, but when one of the largest makers of Windows computers embraced Linux, it was monumental.

Dell remains a major Windows computer manufacturer, but its commitment to Ubuntu and open source ideology remains. The company has slowly been updating the pre-loaded version of Ubuntu from 16.04 to 18.04, with the XPS 13 (9370) getting the newest LTS variant in July. Now, two more Dell laptops are moving up to 18.04 -- Precision 5530 and 3530 mobile workstations

"We wanted to end 2018 on a high note. As of Friday, the developer editions of the Precision 5530 and 3530 mobile workstations are now available with Ubuntu 18.04 LTS. The Precision 7530 and 7730 mobile workstations, built for even more compute-intensive workloads, will be offered with Ubuntu 18.04 LTS soon," says Barton George, Dell.

George further says, "2018 has been a particularly busy one for Project Sputnik. The year had barely begun when the 7th generation XPS 13 developer edition debuted. In Spring the 16.04-based Precision xx30 mobile line began rolling out and in mid-summer the XPS 13 was upgraded from 16.04 to 18.04. With today's news we’re closing out the year with an upgrade of the Precision mobile line."
