Why screen lockers on X11 cannot be secure

Filed under
KDE
Security

Today we released Plasma 5.2 and this new release comes with two fixes for security vulnerabilities in our screen locker implementation. As I found, exploited, reported and fixed these vulnerabilities I decided to put them a little bit into context.

The first vulnerability concerns our QtQuick user interface for the lock screen. Through the Look and Feel package it was possible to send the login information to a remote location. That’s pretty bad but luckily also only a theoretical problem: we have not yet implemented a way to install new Look and Feel packages from the Internet. So we found the issue before any harm was done.

Plasma 5.2 – The Quintissential Breakdown

Filed under
KDE

KDE is one of the oldest open-source desktop projects which can be found today, and over the years it has established a rich history of highs and lows. During some points it has been the undisputed ruler of the desktop world, while other times it had fallen behind or faced hard trials.

A memory everything but forgotten, just over 6 years ago KDE tore itself apart in spectacular fashion to assemble itself anew. Brave users who wandered through the rubble and wreckage saw developers rebuild the KDE before their eyes, witnessing the birth of ‘Plasma Desktop’ and it’s sister project ‘KDE Development Platform’. It was universally understood that this twisted gnarled creature of a computing experience was both hideous yet full of potential, and over 5 years of refining Plasma it had struggled, crawled, hobbled, walked, run, and eventually mature into a fine desktop.

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.

Krita is considered to be a digital painting application, but it's best described as a raster graphics editor. No matter what you call it, the Paris 8 University has decided to drop Adobe's Photoshop and to adopt Krita instead.

NVIDIA Tegra DRM Driver Supports Atomic Mode-Setting In Linux 3.20

The latest work landing in the DRM-Next code-base for the Linux 3.20 kernel merge window is the Tegra DRM driver updates. The Tegra DRM driver is primarily designed to support the Tegra 4 and older SoCs while the Tegra K1 and newer is supported by the Nouveau DRM driver due to the graphics core now being common with their mainline desktop architecture. The Tegra K1's GK20A graphics core is derived directly from Kepler while the brand new Tegra X1 is derived from Maxwell. Regardless, the Tegra DRM driver continues to be actively developed by NVIDIA stakeholders. Read more

LibreOffice 4.4 the beautiful

We are very close to release LibreOffice 4.4 and I thought I’d share my thoughts on the work that has been put into this new branch and what the general idea is about it. LibreOffice 4.4 is unusual; as a major release you may expect some important underlying change in its architecture, or the inclusion of a set of major features. The 4.4 does include several important features and improvements, most notably for Impress and the much forgotten HTML editor (the comprehensive release notes may be found here). But the most important details are not to be found in this area. If you want to understand where the 4.4 branch is headed, I think it is useful to keep two fundamental trends in mind. Read more

Embedded Linux Conference hijacked by drones

The Embedded Linux Conference + Android Builders Summit on Mar. 23-25 in San Jose is about “Drones, Things, and Automobiles,” but drones get the most love. Maybe it’s just our imagination, but the Linux Foundation’s Embedded Linux Conference seems to be getting more interesting than ever. The program increasingly reflects new opportunities for Linux in areas such as drones, robots, automotive computers, IoT gizmos, 3D sensing, modular phones, and much more. For those of you worried that ELC North America is skimping on the basics as it explores the more colorful sides of Linux, rest your mind at ease. There are still plenty of sessions on booting, trace analysis, NAND support, PHY frameworks, power management, defragmenting, systemd, device tree, and toolchain. Geeks still rule! Read more
