Powered by Ubuntu 15.10’s Linux kernel 4.1 LTS, Lubuntu 15.10 Beta 1 is still built around the LXDE (Lightweight X11 Desktop Environment) graphical desktop interface for GNU/Linux distributions. Of course, this means that we won’t be able to try the next-generation LXQt desktop environment on Lubuntu at this time, which should be integrated until the release of the Final Beta build on September 24.
