how to install PIXEL desktop over Raspbian Jessie LITE
By its own, the RPi requires standard & wireless networking, I2C & serial communication. A desktop environment (whatever version) is also required and so is a basic web browser (whatever that is). Other required applications (as separate install) are Python 3.4, TightVNC server, Editra editor, a web server (probably lighttpd), perhaps also some CGI like Perl (not yet established).
Until now I used the full Raspbian package, which worked well. However, there are a lot of useless applications for my given requirement and instead of sudo apt-get remove/purge tons of them, I want the reverse approach, that is to install the LITE version and then only install what is strictly required.
This includes a desktop. I read how to install the "old" desktop, but I didn't found something clear about installing the PIXEL version from scratch (but only how to update from existing desktop, via dist-upgrade or something).
So, question: is there a page that explains how to install PIXEL desktop version over clean Jessie LITE ?
Same question for installing Chromium web browser ?
Python 2.x is not required in my particular case, except if mandatory for some desktop components.
RealVNC server is not desired here, because of its license.
