Welcome to Chromium's Ozone-Wayland

The following message was sent out this morning – I’m copying it here and attaching a cute screenshot of my desktop :) Ozone is a set of C++ classes in Chromium for abstracting different window systems on Linux. It provides abstraction for the construction of accelerated surfaces underlying Aura UI framework, input devices assignment and event handling. http://www.chromium.org/developers/design-documents/ozone Today we are launching publicly Ozone-Wayland, which is the implementation of Chromium’s Ozone for supporting Wayland graphics system.

UI customization on Wayland

Let’s forget for a second about video drivers, whether it has acceleration or not, and all the related issues with hardware support on Wayland. This is all solved. Let’s talk about the user interface (UI) and ways to customize it all over the computing continuum – from phones, tablets and TV box to desktop PCs, Invehicle Infotainment (IVI), aeroplane systems, among others. (I’ve made a cheat sheet here also – Creative Commons Legal Code Attribution 2.

the damn small Wayland API

Wayland 1.0 release is knocking the door and people keep asking “why Wayland if we got X already”, or things like performance, memory consumption, power savings and other kind of advantages on having Wayland instead X. Those are very important points to consider, of course, but for one individual actually programming the graphics system the answer should be straightforward: Wayland API is damn small. 1. But who’s going to program Wayland or X?

X on Wayland

A rather cool feature on Weston compositor is xwayland, to support X11 native applications on Wayland. It’s a quite important feature because gives the compatibility with the “old” windowing system, so say you have an application written on Motif/Xt or even something more “fancy” like a Web browser all tied with GTK2 and whatever dependency, then you better not bother yourself re-writing it to native Wayland or porting to a modern toolkit – it should just work seamlessly on it.

starting on Wayland development

Do you wanna contribute to a funky open-source project? Are you tired of your nerdy and boring community of developers? Are you the one that wants to get rid of X because it’s a giant, old and fat dinosaur in your system? :) Cool, I have a project to solve your problems! While there’s still lot of churn in the protocol, and yet our goal is soon to wrap up all we’ve been doing to a steady and settle-on-the-stone one description, there’s a lot on the implementation side that needs love.

Qt on wayland: howto

To run Qt applications on Wayland is fairly simple nowadays. Thank to Qt developers, they are following up quite well our last changes on Wayland protocol and updating accordingly on Qt5 code base – by the way, the fresh and just released Qt 4.8 does not ship the latest protocol additions, so that’s not the one I’m referring. So, today I’ve set up the last bits of Qt environment on my Intel Pine-Trail pretty easy (yeah, I compile on my tablet :-O).
