Recently, I have created a .desktop file of Firefox application. When I run Firefox, I want to have a dot symbol under the icon of the Firefox when searching it using super key in GNOME just like we get on the default running application.

  • You will have the dot only when the application is already running. – vanadium Jan 23 '20 at 08:30

    @AnkitRajDeo I think that is the default behaviour rite? https://i.stack.imgur.com/6A47U.jpg – PRATAP Jan 23 '20 at 08:33
  • @vanadium yes, you are right. But, it is only happening when application is installed through package manager. In case of some application, i have to create desktop file of that application so that i can open it through search. If that application is running, how can i make orange dot appear under the running application icon. – Ankit RajDeo Jan 24 '20 at 05:47

    Should be there automatically on the icon representing your program. Difficult to help if you do not explain your case in more detail. – vanadium Jan 24 '20 at 08:12

Most probably you don't have a correct StartupWMClass entry in your manually created .desktop launcher for the application. To add one, follow the steps below.

  1. Launch Firefox application in question.
  2. Run xprop WM_CLASS in a Terminal window. The cursor should turn into a crosshair.
  3. Place the cursor over the opened Firefox window and click. You should get a WM_CLASS string for the application in Terminal.

  4. Open the manually created .desktop file in a text editor and add (or modify) the following line

    StartupWMClass=OBTAINED-VALUE

    In place of OBTAINED-VALUE put a value you got from step 3 without any quotes.

  5. Save the .desktop file.

Turn on "Use built in theme". It will show the dots
