On Friday I delivered the first benchmarks of Ubuntu's Unity desktop running on XMir -- the X.Org Server compatibility layer for talking to the Mir Display Server. Those benchmarks showered there was noticeable performance overhead to running XMir with Intel's graphics driver. Later benchmarks showed XMir 2D performance was also negatively affected. In this article are benchmarks looking at the XMir performance with the Nouveau driver.

Yesterday I posted benchmarks of the AMD RadeonSI Gallium3D driver looking at the open-source driver performance for the Radeon HD 7000 series graphics cards. The performance is comparatively very poor right now compared to earlier generations of AMD Radeon hardware that is better supported. But how does the open-source performance compare between the AMD Radeon HD 7000 series and the NVIDIA GeForce 400/500/6000 "Fermi" and "Kepler" on Nouveau? Here's benchmarks.

The LXDE-based derivative of Ubuntu Linux has no plans to be using Mir, regardless of XMir or not.

A Qt Labs project in years prior was QtOpenCL, a Qt module to provide extension classes for QtCore and QtOpenGL to take advantage of OpenCL GPGPU posssibilities. QtOpenCL though hasn't been touched in a couple years and is still living in a Qt4 world. Fortunately, work on QtOpenCL may be restarted.

Launched in May was the Qt for Tizen project to bring the vibrant Qt5 tool-kit to the Tizen open-source Linux platform. After its first alpha release last month, the Qt for Tizen developers have made a heck of a lot of progress and already released Qt for Tizen Alpha 2. The Qt for Tizen Alpha 2 release was done today and is now based upon the Qt 5.2 Alpha and is recognized by the Qt community as an official community-based work-in-progress Qt port.

That's it folks Half-Life 2 and it's episodes are officially out of Beta to join Portal on the Linux platform, it looks like my predictions could be a little off.
