It won’t run Rift apps.

About a year ago Ozone platform abstraction layer started to take its shape in Chromium and we were excited how easily we could support Wayland platform using it.

Some state-of-the-art progress of the project we’re proudly working with: https://www.youtube.com/watch?

A few weeks ago we released Ozone-Wayland and now we’d like to detail for you the development process and strategy behind it… ah, and the title is not developing Chromium, the browser; it’s developing Chromium,** the project**!

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.

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.

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.

A rather cool feature on Weston compositor is xwayland, to support X11 native applications on Wayland.

Do you wanna contribute to a funky open-source project?

To run Qt applications on Wayland is fairly simple nowadays.

Hello Intel Finland :) Here I am now; four months already at OTC big team.

Actually this is not a big news but it’s nice to see on practice X being used on the advanced age :) Here I’ve played with some UI configuration settings, browsed for while, toyed with facebook, opened some photos in the viewer and etc, all for about 5 mi…

Following is the census of 1.10 window for all X infrastructure - raw numbers here.

I am a candidate for the elections 2011 of the board of directors :) Following are my answers based on the questionnaire formulated by the members.

Moikka.

Topic’s name is a funny (and friendly) devotion to GNOME Census.

That’s what I’m using for MeeGo now.

Last week I’ve been in Brazil at 11th International Free Software Forum (FISL) talking about Linux Graphics for Small Devices*.

Usually faster the number of commits, faster the development process.

Previously, the message was for toolkit, now it targets new upcoming developers… okay, if I’d be offensive I could say it targets vendor distributions which care for desktop on Linux :)

We all know since 2006 (?)

So here goes some statistics of the Xorg process running.

This series of documents explore how the memory is used by the Xorg server.

For the first time in life, Xorg is being used in a single platform and for a given device only (other devices have used an X11 implementation but using other non-canonical servers, such kdrive’s based - Tiny-X).

I like UI and I’m not gay.

Just a thought is this something that should be deleted?

Portland, OR I was so proud for the forth time be part of the X crew, this time in Portland.

So last week I posted on lkml an old patch that we were carrying for a long time in the Linux community.

… here I’am :)

Being quick about my last months: finished my Master course, moving to Helsinki tomorrow (!)

One thing that I learned with open communities is when you send a proposal idea and no one replies.

Trying to put some order with all the multiseat documentation found on Web, today I updated the following: Multiseat’s article, in X.Org Foundation wiki: http://wiki.x.org/wiki/Development/Documentation/Multiseat Multiseat’s history, in Wikipedia: http://…

This week our laboratory at university released the MDM utility to ease the process of installation and configuration of a multiseat box.

Unfortunately that model which I described some weeks ago to put the input event delivery of the X server in a separate thread wouldn’t be an advantage.

Input events routed through another thread/process can have bad effects on latency because we can’t guarantee that it will get scheduled at the right moment.

Given that GSoC ‘08 is getting close to the end, strategy number 2 showed more feasible to proceed my work.

GSoC summary #1 - July 29 The current implementation of X Window System relies in a signal scheme to manage the input event coming from hardware devices.

The current DRM kernel modesetting tree is already taking care to update the cursor registers and paint it to the screen.

I really don’t like to read large blog posts.
