RPI new desktop "PIXEL"

RPI's new desktop "PIXEL"
now officially stands for Pi Improved Xwindows Environment, Lightweight.

at the RPI download area now find
Raspbian Jessie with PIXEL
Image with PIXEL desktop based on Debian Jessie
Version: September 2016
Release date: 2016-09-23

and pls read here for all the new setup.
first i download the zip image by torrent (13min for 1.4GB)
but then i try it on my RPI3 just by a dist-upgrade.
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install -y rpi-chromium-mods
sudo apt-get install -y python-sense-emu python3-sense-emu
sudo apt-get install -y python-sense-emu-doc realvnc-vnc-viewer

( sudo apt-get install -y realvnc-vnc-server ) not if use XRDP
and reboot.
first i see LINUX now is 4.4.21-v7
the XRDP window works very slow ( loading the high quality background picture )
as i work temporary via RPI-WIFI-neighbors router-WIFI-PC
can only choose the fishermen picture with little bit less size,
ok, so to change back i select the
and the background color i like.

on 30.11.2016 there is a security update for RASPBIAN "PIXEL" see here
now SSH is disabled again by default
if enabled a warning tells you to change default password
for the HEADLESS: If you want to enable SSH, all you need to do is to put a file called ssh in the /boot/ directory.
To update your existing Jessie image with all the bug fixes and these new security changes, type the following at the command line:

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install -y pprompt

and then reboot.

working on my RPI3 i did a update and later see i lost the WIFI connection,
and on desktop i see in the network icon even a msg that looked like there is no wifi hardware available.
my best idea was to do a complete new setup:
burn 2016-11-25-raspbian-jessie.img 4 371 513 344 byte
make file "ssh" on SD ( in later /boot/ ) so headless work is possible.
passwd raspberry xxx xxx
but my usual settings again give me no WIFI connection.
additionally my XRDP not work any more
and the VNC is little bit different from prior setup
-- its pre installed
-- it must be started by
vncserver :1 ( not asked for password...) via putty
login with "pi" ( not user ) and new password "xxx"
ok, back to default in
and setup WIFI from VNC Desktop works OK!!
now again fix IP's in /etc/dhcpcd.conf
and now RPI3 connects even after removal of ethernet cable,
as WIFI only with default /etc/network/interfaces.
sorry, i still can not say if there is change what makes my default setting ( ssid / wpa in interfaces ) invalid,
but i am relieved that my hardware is ok and i got it running again.

now i did the same change on the old SD card
( ssid wpa move from interfaces to wpa_supplicant.conf )
and it also runs on WIFI again.
but there is still a small difference:
here XRDP still works and VNC gives the "empty" desktop.

so for XRDP lovers the question: how to install XRDP on the very new system?
