Ubuntu MATE 18.04 LTS Will Ship with a New Default Layout Called "Familiar"

Ubuntu MATE's lead developer Martin Wimpress announced that the forthcoming Ubuntu MATE 18.04 LTS (Bionic Beaver) operating system would sport a brand-new default layout for new installations. If you plan on installing or reinstalling Ubuntu MATE this spring, the upcoming 18.04 release sports a new default layout called "Familiar." According to Martin Wimpress, the new layout is based on the Traditional layout with the menu-bar replaced by Brisk Menu, which was used in previous Ubuntu MATE releases. The decision to replace the Traditional layout with the Familiar one was taken due to some technical issues when the development team tried to update it for Ubuntu MATE 18.04 LTS (Bionic Beaver). Traditional will still be available, but not enabled by default, and bears no changes. Read more

Linux Mint 19 'Tara' Cinnamon will be faster

Is Linux Mint slow? Hell, no! The operating system is plenty fast. Speed is in the eye of the beholder, however, and the Mint developers apparently thought app-launching seemed slow when using the Cinnamon desktop environment. They didn't have any proof, but they felt that both Mate and Xfce were faster in this regard. Well, rather than allow their feelings to remain unproven, the Mint devs decided to come up with a speed test to see if they were correct. Guess what? They were! Windows build time was four times slower with Cinnamon compared to Metacity, while recovery time was nearly four times slower too. So yes, app-launching on Cinnamon -- as of today -- is slow comparatively. The big benefit to pinpointing a problem, however, is that it is the first step in solving it. And so, Linux Mint 19 Cinnamon will be faster as a result. Read more
