It’s the first day of October 2015, the month when the second and last release (for the year) of all Ubuntu-based distributions are released. That won’t be until the tail end of the month, but the last pre-stable editions have already being made available for testing.
As best as I can, I’ve been doing my own testing, and accumulating screenshots.
In this article, I’ll share with you some of the screenshots I took from a test installation of Kubuntu 15.10 beta 2. Kubuntu is an Ubuntu derivative that uses the K Desktop Environment. This last pre-stable edition features the latest KDE Plasma 5, so some of the screenshots are a showcase of the latest and greatest from the KDE developers.
Figure 1 shows the login window.

An alternate menu style offers popup features.

Probably the best menu that KDE Plasma 5 has to offer is the Application Dashboard, a fullscreen app launcher that’s available via a widget.

KRunner on KDE Plasma 5 is missing some features of the KDE 4 version, but I’m sure that will be taken of before very long.

The Dolphin file manager.

KDE Plasma 5 System Settings in tree view mode. I prefer tree view to icon view.

The Online Accounts module of KDE Plasma 5 System Settings has support for IBM Sametime, Office 365, and Telegram services.

The User Manager module looks good, but no choice of avatars just yet.

Muon Discovery is the graphical package manager on Kubuntu 15.10. Now looks and feels much better than Ubuntu’s Software Center.

From Muon Discovery, you can actually install KDE Plasma 7 desktop widgets.

That’s all the screenshots I have to share form Kubuntu 15.10 beta 2. Want to take it for a spin yourself? Then download an installation image from here.
