Remmina is in the Linux Mint repositories. Also install RDP and VNC plugins.
Once a connection has been setup with remmina a desktop launcher can be created.
To find the location of connections
cd ~/.remmina ls
The command would be:
remmina -c myconnection
To create a desktop launcher right click on a blank part of the desktop
Select “Creater Launcher …”
Enter the necessary details
To change the desktop icon (in this case from a jar icon)
Once the shortcut has been created right click on it and select properties
Now double-click on the icon in the upper left in the ‘basic’ tab.
This will open a file selection dialogue.
Default icons are probably in /usr/share/icons
The 24×24 icons in the Mate folder seem to work well.
Unfortunately, there is no preview in the select icon browser.
You might want to preview in a regular file browser then copy the address
to use in the icon selection dialogue.
Note: do not work with the ’emblems’ tab, that is a different issue
