Upgraded Kernel & Mesa Yield A Big Boost For Athlon R3 Graphics

Graphics/Benchmarks
Ubuntu

With OpenArena the frame-rate went from just 8 FPS on Ubuntu 14.04 LTS to 19 FPS when using the Linux 3.14 kernel. Linux 3.14 allows for the R3 Graphics to re-clock to their highest performance state compared to Linux 3.13 where DPM isn't enabled by default for GCN GPUs. When going to Mesa 10.2-devel that will be officially released in about one month, the frame-rate rose to 25 FPS... That's over a three-fold performance improvement when pulling in the bleeding edge latest code.

Open-Source Graphics Performance With Unvanquished

Filed under
Graphics/Benchmarks
OSS

To celebrate these improvements being made, I ran a variety of open-source driver tests with this game's test profile. The tests were limited to AMD Radeon and Intel HD Graphics hardware as the NVIDIA GeForce GPUs would end up generating DRM errors when running Unvanquished with its advanced visual settings. The GPUs tested out-of-the-box on Ubuntu 14.04 LTS with this latest Unvanquished version include.

Debian reconsiders init-system diversity

The immediate motivation for a reconsideration would appear to be the proposed addition of elogind, a standalone fork of the systemd-logind daemon, to Debian. Elogind would provide support for systemd's D-Bus-based login mechanism — needed to support small projects like the GNOME desktop — without the need for systemd itself. The addition of elogind has been controversial; it is a difficult package to integrate for a number of reasons. Much of the discussion has evidently been carried out away from the mailing lists, but some context on the problem can be found in this bug report. In short: merging elogind appears to be complex enough that it would be hard to justify in the absence of a strong commitment to the support of non-systemd init systems. It seems possible that this commitment no longer exists across the distribution as a whole; the purpose of a general resolution would be to determine whether that is the case or not. Read more

What you need to know about burnout in open source communities

Earlier this year, I was burned out. Coincidentally, at the time, I was also researching the subject of burnout. It's taken some time for me to take what I researched and experienced and put it into words. Recently, the International Classification of Diseases classified burnout as an occupational phenomenon. It defines burnout as a "syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed." Read more

Raspberry Pi 4: Chronicling the Desktop Experience – Web Browsing – Week 4

This is a weekly blog about the Raspberry Pi 4 (“RPI4”), the latest product in the popular Raspberry Pi range of computers. This week’s blog focuses on an absolutely essential desktop activity. Surfing the web. A web browser is the quintessential desktop application. Everyone needs one, and there is not a desktop Linux distribution around that does not make a web browser available. For Linux, there’s a web browser for every need. There’s heavyweight browsers jammed with a large feature set with addons and extensions. Then there’s leaner web browsers which still offer an attractive graphical interface. And there’s lightweight browsers including console based web browsers too. Read more
