Ubuntu 13.10 (Saucy Salamander) review: Smart Scopes in, Mir out

Filed under
Ubuntu

With relatively little that's obviously new, the final release of Ubuntu 13.10 (Saucy Salamander) seems a somewhat obligatory event. Of course it does feature a new revision of the Linux kernel (version 3.11.0-12) and a new revision of Unity. Also, as with every release, a lot of work has been done improving the various modules that make up the operating system, fixing bugs, eliminating vulnerabilities and improving performance. However, Ubuntu 14.04 LTS, due for release on 17 April next year, will now perhaps come as even more of a shock if its promised big changes are fully realised.

Mir fails to make the cut

Canonical has said that Ubuntu 14.04 and the Unity Next interface, which will support desktop, TV, tablet and smartphone form factors, are dependant on Canonical's new display server, Mir. With this in mind, the Ubuntu developers had hoped to have an early release of Mir running in Ubuntu 13.10 — and indeed it did feature as an option in the beta release, as noted in our Beta 1 preview. Unfortunately, Mir has now been dropped from 13.10 due to technical difficulties and the final release reverts to the X Windows server. Officially this is due to problems with multi-monitor support, but Linux developer Matthew Garrett blogs that, in his opinion, there is rather more to it than that.

SUSE Linux Enterprise High Availability Extension

Historically, data replication has been available only piecemeal through proprietary vendors. In a quest to remediate history, SUSE and partner LINBIT announced a solution that promises to change the economics of data replication. The two companies' collaborative effort is the headliner in the updated SUSE Linux Enterprise High Availability Extension, which now includes LINBIT's integrated geo-clustering technology. Read more

Open source is mission critical for Europe’s air traffic

It is entirely possible to use open source in a highly regulated environment such as air traffic control, says Dr Gerolf Ziegenhain, Head of Linux Competence & Service Centre (LCSC) in Mainz (Germany). Open source service providers can shield an organisation from the wide variety of development processes in the open source community. Read more

  • DRM display resource leasing (kernel side)
    So, you've got a fine head-mounted display and want to explore the delights of virtual reality. Right now, on Linux, that means getting the window system to cooperate because the window system is the DRM master and holds sole access to all display resources. So, you plug in your device, play with RandR to get it displaying bits from the window system and then carefully configure your VR application to use the whole monitor area and hope that the desktop will actually grant you the boon of page flipping so that you will get reasonable performance and maybe not even experience tearing. Results so far have been mixed, and depend on a lot of pieces working in ways that aren't exactly how they were designed to work.
  • GUADEC accommodation
    At this year’s GUADEC in Manchester we have rooms available for you right at the venue in lovely modern student townhouses. As I write this there are still some available to book along with your registration. In a couple of days we have to a final numbers to the University for how many rooms we want, so it would help us out if all the folk who want a room there could register and book one now if you haven’t already done so! We’ll have some available for later booking but we have to pay up front for them now so we can’t reserve too many.

  • Linux Action Show to End Eleven Year Run at LFNW
    Jupiter Broadcasting’s long-running podcast, Linux Action Show, will soon be signing off the air…er, fiber cable, for the last time. The show first streamed on June 10, 2006 and was hosted by “Linux Tycoon” Bryan Lunduke and Jupiter Broadcasting founder Chris Fisher.
