The past weeks, I’ve been working on getting Kwin, the window manager and compositor in Plasma Active<\/a> (and Plasma Desktop ;) to work on top of OpenGL ES instead of OpenGL. After some updating of packages lower in the stack, especially Mesa and parts of Xorg, we now have working OpenGL ES support on our hardware. Today, I’ve finished packaging it as an option on top of our Plasma Active packages. These packages in the :Devel subsection of the KDE:Active repository in the OBS run on top of Balsam Professional and openSUSE 11.4. We will give this some more testing and improve a few things, in order to move to GLES by default. OpenGL ES is very interesting as this is an API often used on mobile devices, so I’m glad that I can state that we’re ready for this. This of course needs proper support in the drivers, something we can not always solve by ourselves. I have been running this successfully on two Intel Atom-based tablets.<\/p>\n

\"Contour<\/a><\/p>\n

All the props of course to to our Akademy-award winning window management and compositing hero, the one and only Martin Grässlin. He’s been working on OpenGL ES support (and a lot of other features to make kwin “ready for the future”) for quite some time already. OpenGL ES support in kwin has been introduced in the recent Plasma Desktop 4.7<\/a> release, a few weeks ago.<\/p>\n

So, is it much different? Nope, it’s very much a thing of underlying technology. There’s no noticable performance improvement, but it runs stable and well. Given that OpenGL ES support has only very recently been introduced in kwin, it’s already surprisingly good. There is probably still a lot of room for improvement, which is something we can investigate now and easily test much better.<\/p>\n

Froscon<\/h3>\n

In the screenshot of the Contour<\/a> shell of Plasma Active, you can see that I’m all set up to go to FrOSCon<\/a> tomorrow, where I’ll be presenting the ideas and demoing the prototypes, hoping to get some feedback on concepts, and give some understanding of the challenges and opportunities we face in this exciting endeavour. And of course show some serious bling. :) If you’re in the area around Bonn, drop by.<\/p>\n","protected":false},"excerpt":{"rendered":"
