Have anyone any idea how it do it?

Solution 1

You can achieve this without needing to install any extra packages.

1. Add your application (synaptic) to the panel
2. Open a lxterminal and navigate to ~/.config/lxpanel/Lubuntu/panels
3. type the following to open the file leafpad panel
4. find the line id=/usr/share/applications/synaptic.desktop
5. change this line to id=synaptic.desktop
6. save and exit leafpad
7. create a local applications menu folder mkdir -p ~/.local/share/applications
8. copy the master synaptic.desktop file: cp /usr/share/applications/synaptic.desktop ~/.local/share/applications
9. edit the newly copied file: leafpad ~/.local/share/applications/synaptic.desktop
10. find the line Exec=synaptic-pkexec
11. change this to Exec=gksudo synaptic-pkexec
12. save, exit leafpad, logout and login.

Graphical option -

Try LxMenuEditor Add in a custom command gksu nautilus or gksu synaptic

Sereenshots (I did not add them directly as they are large)

To install the dependencies

sudo apt-get install lxshortcut zenity

LxMenuEditor itself is a script, save it in ~/bin

mkdir ~/bin
cd bin
wget http://opendesktop.org/CONTENT/content-files/138298-LxMenuEditor
mv 138298-LxMenuEditor LxMenuEditor
chmod a+x LxMenuEditor

to run it manually, ~/bin/LxMenuEditor

Once you log out and log back in, ~/bin will be on your path and you can either make a menu entry of it or open a terminal and type LxMenuEditor

Your other option is to manually edit your menu or write a launcher. Writing a launcher is not too hard , they are located in /usr/share/applications as *.desktop files. You can use most any .desktop as a template, just set an icon and use gksu synaptic as the action / command.
