Kubuntu is a special version of Ubuntu that replaced the controversial Unity user interface with the KDE desktop environment. It is known among the Ubuntu community as the official KDE flavor of Ubuntu Linux.
The Wily Werewolf edition of Kubuntu will be officially released on October 22, 2015 and it will be supported by Canonical and the Kubuntu community with software updates and security patches for 9 months, until July 2016.
Distributed as 32-bit and 64-bit Live DVDs
Kubuntu 15.10 is distributed as two Live DVD ISO images, one for legacy 32-bit (i386) computers and another one for modern 64-bit (x86_64) machines. Both ISOs are hybrid, which means that you will be able to write them on either a USB flash drive or a DVD disc.
Boot options
The boot options are identical with those that were present in previous versions of the distribution, which means that, by default, the Live DVD will boot automatically in approximately 10 seconds from the moment the users boots the ISO image from the BIOS of the PC.
Available boot options include the ability to start Kubuntu with default settings, support for testing the memory of the PC, the ability to boot an existing operating system from the local disk drive, as well as support for checking the integrity of the bootable medium (only if booting from a DVD disc).
Additionally, you can choose a different language, enable various accessibility options, change the keyboard layout, select a different mode, and activate various other useful functions that will ensure your special hardware is supported.
The next-generation KDE Plasma by default
Kubuntu 15.10 is the first ever version of the operating system to feature the next-generation KDE Plasma desktop environment by default, replacing the old-school KDE 4 user interface. It includes all the KDE packages and applications that are distributed as part of the KDE Applications 15.04 software suite, as well as all the other KDE5 technologies, including KDE Frameworks 5.
When booting the Live DVD, users will be asked if they want to try the live session of start installing the operating system on their computers. Choosing the live mode will allow you to test drive Kubuntu without installing anything on your computer. The desktop environment features the same traditional layout consisting of a single taskbar located on the bottom edge of the screen and a Desktop Folder widget on the desktop.
Offers the same great collection of software and apps
Probably the best thing about Kubuntu 15.10 is that it offers the same great collection of software and apps that were available in previous editions of the operating system. Besides all those great KDE apps, the distribution comes with the Mozilla Firefox web browser and the entire LibreOffice office suite.
