A version of the popular Ubuntu Linux operating system is coming later this year for mobile internet devices and subnotebooks. Canonical, the commercial sponsor of Ubuntu, said on Monday that it plans to demonstrate the new version, Ubuntu Netbook Remix, at the Computex trade show in Taiwan this week. Smaller devices based on Intel's Atom processor have proved popular with PC makers recently. Manufacturers such as Acer and others are planning such devices. The Ubuntu release, expected later this year, will be based on the standard Ubuntu Desktop Edition and reworked for Atom-based mobile devices, Canonical said. The company said it is working with a number of original equipment manufacturers, but did not identify those companies. The Ubuntu announcement was expected. Canonical chief executive Mark Shuttleworth mentioned Netbook Remix in an interview with The Guardian last month.
