Technical Limitations of Client-Side-Decorations

Filed under
KDE
Software

I was just made aware of the fact that you can open Alt+F3 in Plasma popups and that helped to produce this wonderful screenshot (sorry Eike and Plasma devs for destroying your apps in such a horrible way):

As we see all windows have KWin decorations and they should not have them. Yakuake has a kind of own CSD – you see the controls at the bottom. For Yakuake it’s totally fine to use the own controls as it has a very special usecase. Also all the Plasma windows should not have decorations as they are part of the workspace and by that not traditional windows.

So this is a technical and unsolvable problem for all windows which want to have CSD: the window manager may reparent the window and the window has no control over it.

And this issue is really unsolvable

Fedora Server 22 Benchmarks With XFS & The Linux 4.0 Kernel

Fedora 22 is shaping up quite well across the Fedora Workstation, Server, and Cloud offerings. Out of curiosity, this week I ran some initial comparison tests of Fedora Server 21 vs. Fedora Server 22. Fedora Server 22 notably switches its default file-system over to XFS from EXT4 for new installations. Fedora Server 22 also has the other same updated packages to Fedora 22 like the Linux 4.0.2 kernel and GCC 5.1.1. Read more
