I just installed the application Computer Janitor.
The icon is now accessible in the Unity Launcher.

Personally I think that the Unity toolbar is great for "normal" applications, but for system applications I prefer that they are not so easily accessible and the best place is then in the "System Settings" window.

So I can remove this icon from the Unity Launcher, but how can I add it to the "System Settings" window?

enter image description here

  • Confusing: In Ubuntu Software Center I find this application as "Computer Janitor". But packages.ubuntu.com/computer-janitor-gtk doesn't exist - the package computer-janitor-gtk itself links in its description to wiki.ubuntu.com/CleanupCruft - where this application is called system-cleaner - which doesn't exist in Ubuntu Software Center ... – Jakob May 8 '12 at 8:50
  • my translation was not right, the english name is Computer Janitor as you suggested - thanks for editing my question. – Boris May 8 '12 at 8:58

    @Boris - I would strongly advise you against using computer janitor. It breaks more things than it fixes. If you want a cleaner - try bleachbit or ubuntu-tweak as per askubuntu.com/questions/2243/ccleaner-equivalent – fossfreedom May 8 '12 at 10:56

Add the starter to "System Settings":

Press Alt+F2 and run gksu gedit /usr/share/applications/computer-janitor-gtk.desktop, enter your root password when asked.

Add X-GNOME-Settings-Panel;X-GNOME-SystemSettings; to the line "Categories=System;Settings;PackageManager;GTK;".

Add the new line X-GNOME-Settings-Panel=computer-janitor-gtk to the end of the file, save and close.

Remove the icon from the Launcher via rightclick → Remove from Launcher.

And you get:

system settings

Launchers of applications are stored in ~/.local/share/applications or in /usr/share/applications/ (which to edit you have to open with gksu nautilus - but don't mess up your system!). Note: When an application becames updated, often the .desktop file becames updated, too (in /usr/..., not in ~/.local/...)

More info about Launchers you find in the Community Help Wiki.

  • Perfect it works. Could you give me more details so I can later do it for any other applications. So far I understood that we get a *.desktop file for every applications but I would never find myself to do these modifications without your advise. Is there a link describing the content of these *.desktop file ? – Boris May 8 '12 at 9:22
  • Thanks for adding the image! I updated the answer with some details. – Jakob May 8 '12 at 19:44
