# Ubuntu – Why does the custom launcher open under a separate icon

iconslauncher

I've created a custom launcher file:

[Desktop Entry]
Type=Application
Name=P4V
Comment=Perforce Visual Client
Icon=/usr/lib/p4v/P4VResources/icons/P4-V_128x128.png
Exec=/usr/bin/p4v
Terminal=false
Categories=Development;


And dragged this file to my launcher. However, when I click the icon, it opens the application under a 2nd, different icon (I click the top one, it opens the application under the bottom one):

The bottom icon isn't present until after I launch the application using the top P4v icon that I manually added.

### If an application produces a second icon, not being a generic one

If an application generates a second icon in the Unity launcher other than a a grey, generic icon, there must be already an (other) existing launcher, calling p4v in its main command:

An application's .desktop file by definition has a "main" command in the first line, starting with Exec=. This is the command that is run when the icon is clicked in the (Unity) launcher. Apart from that, a .desktop file can have one or more shortcut- sections, available when you right-click on the representing icon in the Unity launcher.

### Multiple .desktop files calling the same application in their main command

The symptoms you are experiencing can happen when more than one .desktop file in either /usr/share/applications or ~/.local/share/applications have the same ("main-") command in their first Exec= line, but the files are differently named.

P4v by default should install (and probably has installed) a .desktop file, named p4vasp.desktop in /usr/share/applications.

How to fix
Your problem should be fixed if you remove your own (probably local) .desktop file, then run p4v from Dash and pin it to the launcher.

### What if you want to customize the existing launcher?

If you want to change the .desktop file's behaviour or e.g. its icon:

• copy the file from /usr/share/applications to ~/.local/share/applications
• don't change the file's name
• open the file in gedit (drag it over an opened gedit window) and make the changes you'd like
• log out and back in, the local version of the .desktop file will overrule the global one.

To revert, simply remove the local one, log out and back in.
