Tizen 3.0 Features & Tizen Lite Unveiled

We have just learned about NX300M camera, the first Tizen device, based on Tizen 1.0, but development of the new mobile operating systems is still going on, and the key features of Tizen 3.0, as well as Tizen Lite, Tizen for low-end hardware, have been unveiled at the Tizen Developer Summit on 11th of November 2013. Tizen 3.0 features: Update core OS and toolchain Multiple user support 64-bit Intel and ARM architecture support (New) 3D UI Framework with 3D rendering for 2D and 3D objects in 3D, and a dynamic animation library WayLand based compositor replacing X Crosswalk – HTML5 based application runtime based on Chromium/Blink Tizen 3.0 release is scheduled for Q3 2014, so the first Tizen smartphones and tablets which are expected for Q1 2014 will probably ship with Tizen 2.2.1, or even possibly with an earlier version. Android KitKat 4.4 has been optimized to run smoothly on device with just 512 MB, but the newly announced Tizen …

LinuxCon Europe 2013 Schedule – Web Technologies, Debugging Techniques, Wayland, and More

I’ve just received an email from the Linux Foundation saying the schedule for LinuxCon and CloudOpen Europe 2013 had been made available. The conference will take place for 3 days (October 21-23, 2013) in the Edinburgh International Conference Center, Edinburgh, United Kingdom. There will be over 100 conference sessions, and several co-located events including: Automotive Linux Summit, the Embedded Linux Conference, Gluster Workshop, KVM Forum, Tizen Summit, Xen Project Developer Summit. As I’ve recently done with LinuxCon North America 2013 and ARM TechCon 2013, I’ll make a virtual schedule with selected developer sessions using the event’s schedule builder. You may find out several sessions will also be given in LinuxCon North America. Monday – 21st of October 11:00 – 11:50 – Bluetooth Smart Devices and Low Energy Support on Linux by João Paulo Rechi Vita, INdT This presentation will cover a brief introduction on how the Bluetooth Low Energy technology works. Then it will present the current status of its …

RebeccaBlackOS is a Linux Distribution Showcasing Wayland

nerdopolis, a developer and a Rebecca Black fan, has been maintaining a Linux distribution called RebeccaBlackOS that uses Wayland’s reference compositor Weston as the default for handling its graphical user interface, and automatically start “Friday” song as it boots. This distribution actually supports both Wayland and X, as even though QT, GTK, EFL (Enlightenment Foundation Libraries), Clutter, and SDL (Simple DirectMedia Layer) have all been compiled to support Wayland, many apps don’t work with Wayland, so Xwayland provides a way to run many, but not all, X apps in Wayland. You can try the latest 1.8 GB ISO image (24 May 2013), which is based on 32-bit Kubuntu 13.04, by transferring it to a USB flash drive via Unetbootin, or by using the ISO directly in VirtualBox (it will then use the framebuffer). I planned to try it before writing this post, by the “18 hours, 10 minutes remaining” message quickly dissuaded me from doing so. H-Online reports it does …

Future Versions of Ubuntu To Feature Mir Display Server Compatible With Android Graphics Drivers

The X server is getting old, and many developers complain it’s not an optimal solution anymore due to its (over) complexity, which was why Wayland was developed. However, it turns out Ubuntu will not use Wayland, but instead their own display server called Mir which will be used in all form factors from phones to desktops. Phoronix has provided a quick summary about the key aspects of Mir: Mir is a new display server being developed at Canonical and it is not based on X.Org or Wayland. Android graphics drivers will be supported. Existing DRM/KMS/Mesa/GBM (the open-source Linux graphics drivers) will work. Canonical is pressuring the binary blob vendors to make their drivers compatible. There will be support for legacy X11 applications through an integrated root-less X.Org Server. Canonical will natively support GTK3 and Qt/QML toolkits with Mir. Mir will be used for all form factors from Ubuntu Phones to the Ubuntu Linux desktop. Mir should be ready for Ubuntu …

Linux Conference Australia and FOSDEM 2013 Videos are Now Online

FOSDEM 2013 took place last week, and the organizers are in the process of uploading videos. Up to now, 5 main tracks sessions have been uploaded (Firefox OS;  Free, open, secure and convenient communications; FreedomBox 1.0;  Samba 4; and systemd, Two Years Later) as well as over 20 lightning talks. You can find the videos at http://video.fosdem.org/2013. You may also want to check my previous post for a lists of interesting talks, and I’ll probably feature some FOSDEM 2013 videos in this blog, at least the open source GPU driver talk. Linux Conference Australia took place on January 28 – February 1, 2013, and the 5-day conference featured lots of talks including several dealing with graphics in Linux, and one developer apparently trashing X in terms of complexity and performance, and explaining how Wayland was better. Others Linux sessions dealt with subject such as 3D printing, supercomputing, Arduino, big.LITTLE processing, open source, git, Raspberry Pi, UEFI, and much more. You …

Qt on Embedded Systems – ELCE 2012

Lars Knoll, chief maintainer for the Qt Project, gives a presentation about Qt on embedded systems, including a demo with the Raspberry Pi at the Embedded Linux Conference Europe 2012 in Barcelona, Spain. Abstract: For well over 10 years, Qt has been used in many types of embedded devices, ranging from high-end medical systems, through mobile phones and smartphones, all the way to simple devices like coffee makers. This presentation will show some of the work that has been put in Qt throughout the years to support embedded devices, some of the challenges that the development team faced in order to bring a fully-featured desktop toolkit to resource-limited devices, along with solutions they came up with. Time permitting, the presenter will also show Qt demos running on an embedded device. This session is intended for embedded application developers looking to make use of the capabilities of recent hardware, as well as decision makers looking for technology to enable their product …

Wayland Library: X11 Display Server Replacement for Linux

The X Window System has been implemented in Linux since the beginning and manages the graphical user interface of most Linux distributions, although some embedded systems do without X11 and use lightweight graphics libraries such as Nano-X, SDL, DirectFB etc… X11 is invisible to the end-user but does all the hard work needed to have Gnome, KDE and Unity user interfaces work properly and smoothly. However, in recent years, GNU/Linux desktop graphics has moved from having numerous rendering APIs talking to the X server which manages everything towards putting the Linux kernel in the middle with direct rending (e.g.  OpenGL, VDPAU/VAAPI) with window systems taking the backstage. This new architecture  provides a much-simplified graphics system offering more flexibility and better performance. The problem is that the X Window System is highly complex, a complexity that is not really needed with the newest version of the kernel. That’s where Wayland protocol comes into play. Wayland is described as follows: Wayland is a …
