The Cog Icon Conundrum

So, what's behind the mysterious case of cog icons in Dash? When you run an application from the terminal, it's expected to display a nice icon or a dot under the main icon in Dash. However, some applications, such as arduino-ide, display a cog instead. This can be frustrating, especially if you're used to seeing icons for your applications.

Possible Reasons Behind Cog Icons

There are several possible reasons why cog icons appear in Dash:

Lack of Icon Files: If an application doesn't provide an icon file, Dash will default to displaying a cog.
Incorrect Icon Path: If the icon path is incorrect or not properly configured, Dash may display a cog instead of the icon.
Application Issues: Some applications may have issues with their icon handling, leading to cog icons in Dash.
Dash to Dock Configuration: In some cases, the configuration of Dash to Dock may be causing the issue.

Step 1: Check the Application's Icon File

First, check if the application has an icon file. You can do this by searching for the application's icon file in the /usr/share/icons directory. If the icon file is missing or not properly configured, Dash will display a cog.
