Icons not working in .desktop file

  • 772

I wanted the program Arduino to be accessible from the dash, so I put this in ~/.local/share/applications/arduino.desktop:

[Desktop Entry]
Type=Application
Name=Arduino IDE
GenericName=Arduino IDE
Comment=Open-source electronics prototyping platform
Exec=/home/username/Programmer/arduino/arduino
Icon=arduino
Terminal=false
Categories=Development;IDE;Electronics;
MimeType=text/x-arduino;
Keywords=embedded electronics;electronics;avr;microcontroller;
StartupWMClass=processing-app-Base

I have a transparent png icon (600 x 315 pixels) called arduino.png in the same directory, but it didn't work. It says here :

Application icons should be available at least at a resolution of 48x48 pixels. Place the icon in /usr/share/icons/hicolor/48x48/apps/

So I put it there, too, but I still don't have an Arduino icon associated with the desktop entry. How do I do this?

icons .desktop unity-dash 20.04

  1. I believe you can simply write full path to the icon in corresponding line:

    Icon=/usr/share/app-install/icons/arduino.png

    Put the arduino.png icon into the same folder as the application binary, then...

    Edit your arduino.desktop file and...

    Change this:

    Icon=arduino

    To this:

    Icon=/home/username/Programmer/arduino/arduino.png

    Save the edit.

    If you decide to put the arduino.desktop file on the ~/Desktop, right-click on the arduino.desktop file, and select "Allow Launching".

    Launch arduino using the normal SUPER key method, and once the icon appears in the dock, right-click on the icon, and select Add to favorites.
