KWin on speed

Filed under
KDE

With the 5.2 release basically done, I decided to do some performance investigation and optimizations on KWin last week. From time to time I’m running KWin through valgrind’s callgrind tool to see whether we have some expensive code paths. So far I hadn’t done that for the 5.x series. Now after the switch to kdecoration2 I was really interested in the results as in the past rendering the decoration used to be a bottle neck during our compositing rendering loop.

Fedora 22 Will Aim To Use Plasma 5 For Its KDE Desktop Experience

Filed under
KDE
Red Hat

For KDE users on Fedora, the Fedora 22 release is seeking to focus on the still-maturing Plasma 5 shell that's powered by KDE Frameworks 5 and Qt5.

An in-progress change proposal for Fedora 22 is to use Plasma 5 (and KF5/Qt5) with the latest KDE components to be fully-packaged in time for F22, an upgrade path be provided from KDE 4, and to retire any KDE 4 packages in Fedora that aren't compatible with the "KDE 5" work.

Shadow Mapping in Qt3D 2.0

Filed under
KDE

One of the biggest driving factors behind the design of Qt3D 2.0 is the ability to configure the renderer in order to accommodate custom rendering techniques. In this blog post I will explain how to render a scene in Qt3D with shadows.

Improving KDE's support for Korean (and other CJK languages)

Filed under
KDE

In addition to my usual work on things like Plasma and Konversation, I've been hacking away on bugs that pose barriers to the use of the Korean language and writing system in KDE/Qt systems lately (I took up studying Korean as a new hobby last year). As a bonus, many fixes also tend to help out users of other CJK (Chinese, Japanese, Korean) languages, or even generally of languages other than English.

KDE
Linux

Black Lab Linux, a distribution based on Kubuntu and that uses one of the latest KDE packages, has been upgraded for version 6.0 and is now available for download.
Users might associate the name of Black Lab Linux with a GNOME desktop, but the developer also had a KDE edition of the operating system, which they didn't bother too much to upgrade. Now they have finally got around to it, and backed by popular demand, and they made quite a few improvements.

‘Goodbye Photoshop’ and ‘Hello Krita’ at University Paris 8

Filed under
KDE

According to François, “we don’t want to let ourselves be pushed around and make choices that go against our beliefs. This freedom of choice is exactly the advantage that a public institution has over a private school.” All other animation schools in France, fellow members of RECA (the network of French schools of animation), are watching ATI avidly to see how this new methodology works out.

Filed under
KDE

The developers from the KDE project have made some important changes and you might have noticed that it no longer says KDE Applications and Platform, jus KDE Applications. Also, you might have spotted the fact that KDE SC is also gone. The project has been split into KDE Frameworks, KDE Plasma, and KDE Applications and they are now quasi-independent.

​No reboot patching comes to Linux 4.0

One reason to love Linux on your servers or in your data-center is that you so seldom needed to reboot it. True, critical patches require a reboot, but you could go months without rebooting. Now, with the latest changes to the Linux kernel you may be able to go years between reboots. Read more

Linux 4.0-rc2

So rc2 missed the usual Sunday afternoon timing, because I spent most of the weekend debugging an issue that happened on an old Mac Mini I have around, and I hate making even early -rc releases with problems on machines that I have direct access to. Even if it only affected old machines that actual developers are unlikely to have or at least use. Today I got the patch from Daniel Vetter to fix it, so instead of doing a Sunday evening rc2, it's a Tuesday morning one. Go get it. It works better for the delay. Other than that little one-liner i915 fix? Not much, actually. It's been a very quiet week, for being this early in the release process. Sure, 3.19-rc2 was even smaller, so it continues a trend, but that was the xmas week. I hope this low volume is just because the 4.0 merge window itself was somewhat calmer than most recent releases. But I suspect the real reason is that the driver and networking trees from GregKH and davem are pending, and didn't make rc2. We'll see. Anyway, the shortlog is appended, and testing is appreciated, Linus Read more
