A business doesn’t need a fleet of GNU/Linux guys to run IT. A few will do because one person can easily manage thousands of PCs with FLOSS. There are no licences to count, no networking limitations, no CPUs to count, … They just have to run the software any way that makes sense.
Open-Source Radeon 2D Performance Is Better With Ubuntu 14.10
In this article are graphics card tests going back to the Radeon HD 4870 and even going back that far are 2D improvements with Ubuntu 14.10. However, most interesting is the Radeon HD 7000 series and newer where GLAMOR is used for 2D acceleration rather than UXA. GLAMOR leverages OpenGL for 2D acceleration and with X.Org Server 1.16 the GLAMOR support went from being an independent library to a highly-optimized implementation within the X.Org Server. Ubuntu 14.10 uses X.Org Server 1.16.0 along with Mesa 10.3.0, Linux 3.16, and xf86-video-ati 7.4.0.
What if… KDE Started using Client-Side Decorations?
The main technical challenges faced by KDE developers is ensuring application consistency will continue to work under various form-factors. When Kwin (the KDE window manager) controls window borders, it can quickly and gracefully adapt to multiple form-factors. For example, in Plasma active space is at such a premium KDE can hide window decorations and embed them into the workspace itself.
The other technical challenge is protocol and cross-enviornment consistency. It’s known that CSD-enabled applications can look extremly awkward when window borders are wrapped around an application not designed to use them. In addition, protocols for drawing CSDs on Linux are a mish-mash at best, and CSD code tends to be far less portable to other desktop environments. Compounding that, KDE has additional features (such as window tabbing) which are inherently incompatible with the feature.
GNOME: A WEEKEND HACK
I’ve been working on making GtkInspector use a different display connection. This helps isolating it from some of the changes you can trigger from inside the inspector UI. Then I thought, why not use a different backend ?!
We did enough work on GDK backend separation that it could almost work. But since we didn’t add API to actually connect to specific backends (users and applications get some control with GDK_BACKEND and gdk_set_allowed_backends()), nobody has ever used multiple backends in the same process. And things that don’t get used don’t work. So some fixes were necessary.
