To answer my own question, this is an lxpanel plugin called lxplug-network and the source code is found here:
It is based on 'Network Configurator' (a.k.a. dhcpcd-ui) by Roy Marples which is found here:
Create a file /home/pi/Desktop/test.desktop:
bash script named test (UTF-8) in /home/pi dir:
echo hello world

Edit the /boot/config.txt file and add the following :

Most likely, you'll need to pick a language and a graphics library or GUI toolkit.
The way that the GUI is rendered on a Linux system is relatively simple, once you understand what each part does. We don't need a really in-depth knowledge of each part, but I'll give you a brief summary, with the aid of a nice illustration I found:
Illustration of the ...
Xorg often needs root permissions to run properly, so it can be problematic to start it as a non-root user from the console. If you want to run it manually without sudo, you should install xserver-xorg-legacy package containing a wrapper which will get root permissions for you via suid bit.
Alternatively, set up XFCE as your default desktop environment (the ...
You don't mention which distro you are using, but assuming you are at the Raspbian command prompt and looking to start the graphical desktop, you can switch to the desktop (GUI) mode by typing:
If you want your Pi to always start in GUI mode. Begin by launching the configuration tool with the following command:
Then select: Boot ...
The error ---[end Kechallengernel panic - not syncing: VFS: Unable to mount root fs unknown-block(179,7)

is often mentioned when a corrupt image have been transferred to a SD card or when a SD card is faulty or kernel bugs.
I have replaced a corrupt SD card due to this cause and that solved my challenge.
GUI in Linux is modular and client-server. A display manager (as its name suggests) manages your displays, and nothing more. You will need an X server (which doesn't have to be running on the same computer BTW) to have any displays in the first place, and a desktop environment if you want to have something on your display besides a mouse pointer.
You can install the LXDE desktop on your RetroPie image:
If you want to boot directly to your desktop, go to "RetroPie configuration" (in EmulationStation) and select "raspi-config" and change the boot behavior to desktop (Enable Boot to Desktop/Scratch):
Raspberry Pi's don't have USB 3.0 so it's going to default to USB 2.0 which is slower, but if you're sharing it over a wireless that's slow anyway, so yes it should work fine. You'll just have USB overhead plus wireless. Do you already know how to share the storage attached to the pi?
You could attempt to use the inbuilt ssh command in your terminal emulator if ssh server is enabled on the other PI; you can enable it on a headless PI by putting a file with no extension in the boot partition on the SD card.
If you require a graphical desktop use sudo raspi-config in the remote ssh connection and enable vnc server. Than on the original PI ...
It is not possible to run a cloned installation from a Raspberry Pi with ARM processor on an intel processor based desktop computer. The operating system and its programs must be compiled for the processor that it will run.
You may consider to use
Debian Buster with Raspberry Pi Desktop for PC and Mac. But this is not Raspbian. It is based on Debian Buster ...
Yes, it's called VNC Viewer, and you'll find it in the "Recommended Software" app (under Preferences in the Raspbian desktop menu).
Or, if you prefer the command line, you can do "sudo apt install realvnc-vnc-viewer".
Thanks to everyone that answered, but I've already found a solution. I used rdektop and systemd . I created a service called remote.service and configured that file to if it closes or exits it starts again.
Install rdesktop and then create a service like so:
sudo nano /lib/systemd/system/remote.service
I think for a period Raspbian shipped with wicd to configure WiFi.
If anyone is looking for other connection managers:
There's a command line version if wicd called wicd-curses.
nmcli is the reference NetworkManager command line interface.
nm-applet is the panel tool found on most heavier weight distributions like Ubuntu for interfacing with NetworkManager....
You haven't specified your Distro - however, if you run the command
it should open up a window that you can change the configuration on. From there go to
7) Advanced Options
Then choose what you think would work best. You can even do this from Putty.
I had an issue with my VNC where it wouldn't show the screen at all....
You'll need to install a VNC server. TightVNC is a good choice. AdaFruit has a great tutorial:
VNC Remote Control- Raspbian
You can then use the installed VNC client to connect.
You can always install TeamViewer as a quick and dirty solution as well
TeamViewer Raspian ARM
Whether you have the normal RealVNC mirroring of your desktop you can create a virtual desktop (or multiple virtual desktops - if so inclined).
You can create a virtual desktop (on the Pi or via ssh) by running vncserver.
This will produce something like:-

An upgrade to a new version of a debian system will replace nearly all old packets, deinstall no more needed packets and install additional ones. It must use the old configuration (-files) and adapt them to the updated needs. This all is a very complicated task and needs clean defined dependencies of the packets. Debian with its packet manager is able to do ...
You can try to switch off the backlight if available for your display. On the command line you can do it with:
rpi ~$ sudo /bin/sh -c 'echo "0" > /sys/class/backlight/soc\:backlight/brightness'
and on again:
rpi ~$ sudo /bin/sh -c 'echo "1" > /sys/class/backlight/soc\:backlight/brightness'
wrote a bash script with folling content:
sudo shutdown -r +10

sudo reboot now

and fill in the path to bash script, before the exit 0 statement:
bash /path_to_bash/bash_script.sh &
of course you could do ...
It sounds to me like you want GoToDesktop instead:

Just to clarify a bit, RetroPie is a collection of packages installed on top of Raspbian. There is no need to manually install RetroPie on top of a clean Raspbian image in order to have a "desktop". From RetroPie, you can go to the command line and install any desktop environment that you choose. If you want to replicate a vanilla Raspbian experience, you ...

Assuming SSH is enabled, you should be able to run desktop headless just fine. I don't see what would be the point as many resources would be used to draw windows and such which you wouldn't see. You can check what's happening process wise with

I had the same problem as you with wifi, to fix it you need to add the following o /etc/wpa_supplicant/wpa_supplicant.conf
Change the ssid and password to what you are using.
Then add the following to /etc/network/interfaces:
