Self-hosted GLES on ChromeOS, part two

This is a follow-up post from an earlier guest post by Blu about OpenGL ES development on Chrome OS. One can’t practice real-time rendering to disk files for long ‒ it’s just unnatural. So after checking that my habitual GLES tests work as intended on ChromeOS when rendering to an off-screen-buffer-subsequently-saved-to-a-PNG, the next step was to figure out a way how to show frames on screen at a palpable framerate, if possible. Being as new to Chrome OS as the next guy, I had to start from scratch with ‘How to show EGL surfaces on screen fast’. In the comments section to the first article William Barath kindly mentioned that there was a wayland client library on Chromebrew, so I decided to pursue that as I had had (positive) prior experience with wayland. Long story short, the established way on most platforms for connecting wayland to EGL (or vice versa) is to ask wayland/weston for an EGL-compatible window surface, and …

Maynard is a Wayland based Lightweight Desktop Environment Designed for the Raspberry Pi and Lower-end Hardware

With 3 millions board already sold, the Raspberry Pi board is clearly the most popular ARM Linux development board, and must be one of the most successful Linux device that’s designed to run a Desktop environment. However, the Broadcom BCM2835 processor and lowly 512MB makes it hard to run fully fledge desktop environment such as KDE and Gnome, so most people run LXDE via Raspbian operating systems, and it is much more manageable. However LXDE does not support Wayland, which is supposed to replace the X windows system, and it may not look as nice as it could. So the Raspberry Pi foundation and Collaborra have worked together on a new desktop environment called Maynard that leverages Wayland, and is supposed to be “functional, light and pretty”. This Wayland implementation is based on Weston + GTK, and is using the hardware video scaler (HVS) found in Broadcom BCM2835 to make everything nice and smooth. Although this is still work in …

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 …

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 …
