From within your console go to /usr/share/applications and there look for all synaptic.desktop files. Do with a "ls synaptic*" command. This directory contains the launchers of all applications (*.desktop file = launcher)
I find 2 in a Lxde mini install:
$ ls synaptic*
When I display their content (ie: with the "cat" command) one has a line that say "only shown in kde" and the other "not show in kde". One has an icon named "synaptic" and the other an icon named "synaptic.png".
/PS : a command line for scrot, such as "scrot -c -d 6 mypicture.png" allows you to have 6 seconds to reduce the console to the panel so that the console is not seen on the screenshot. (And put a name of your own to the shot).
-c : for count
-d : for delay.
For more see "man scrot".
