A new and much better version of Exton|OS is ready. I have replaced kernel 3.16.0-21-exton with kernel 3.19.0-5-exton. (Kernel.org‘s stable kernel 3.19.0, released 150209). With kernel 3.19.0 there is no real need to use Nvidia proprietary graphic drivers since this kernel has better support for the open-source Nvidia driver Nouveau than any other older kernel.
Desktop Environment and programs
The Desktop Environment is Mate 1.8.1. (A fork of GNOME 2. It provides an intuitive and attractive desktop environment using traditional metaphors for Linux and other Unix-like operating systems). Kernel 3.19.0-5-exton. (Kernel.org‘s stable kernel 3.19.0, released 150209). Program content: Firefox, Gimp, Google Chrome (added for Netflix), Vlc and GParted. Also all necessary additions in order to installprograms from source. All packages have been updated to the latest available version as at February 11, 2015. Study the full package list.
