PeppermintOS 9 is the latest release of Ubuntu-based distribution featuring a desktop environment mashup of Xfce and LXDE components. The latest release nearly completes a process begun several upgrades ago, using more Xfce elements and fewer LXDE components.
Based on Ubuntu 18.04 LTS (Bionic Beaver), Peppermint OS 9 is using the Linux 4.15 kernel and supports both 32-bit and 64-bit hardware architectures. Highlights of this release include a new default system theme based on the popular Arc GTK+ theme, support for both Snap and Flatpak universal binary packages via GNOME Software, which will now be displayed in the main menu.
Also installed by default is the Menulibre menu editor, the Xfce Panel Switch utility, xfce4-screenshooter as default screenshot utility instead of pyshot, and xfce4-display-setttings replaces the lxrandr utility for monitor settings. The Htop system monitor utiliy is available as well and has its own menu item, and the Mozilla Firefox is now the default web browser instead of Chromium.
