Filed under
HowTos

Configuring FVWM can seem like a chore at times. Indeed, there are certain aspects of it that are easy - and some that are less so. I've been helping people configure FVWM for some time now, and while I have delved into some of the more esoteric regions of FVWM, it seems that many people find the use of Style lines the hardest aspect to grasp. Hopefully this article will help clarify things.

Netrunner's Unique Blackbird Soars to New Heights

Blackbird, Netrunner's version 19.01 release, hit the download servers on Jan. 14, and this distro deserves to be considered bleeding-edge. Netrunner is a step ahead of other KDE distros, thanks to its solid integration of classic KDE desktop performance with Web-based applications and cloud services. That said, if you aren't fondness of the K Desktop, Netrunner may leave you wanting more desktop simplicity. For that you must look elsewhere. KDE is the only desktop available from the Germany-based Blue Systems development team. Blackbird is based on Debian's "Testing" branch. Its developer brings some aggressive updates to the distro that propel it ahead of other distros' regular development cycles. The main updates include KDE Plasma 5.14.3, KDE Frameworks 5.51, KDE Applications 18.08 and Qt 5.11.3 for its essential security updates. Linux Kernel 4.19, Firefox Quantum 64.0 and Thunderbird 60.3 push the envelope as well. One of the more noticeable new features in Blackbird is its new Netrunner Black theme. This theme is based on a dark-toned contrasting visual. It uses the Kvantum theme engine, plus the Alpha-Black Plasma theme, to produce a more 3D-looking design. Read more
