Ubuntu – Searching a application name returns “sorry no match” in Ubuntu 14.04

14.04

All was working well in my Ubuntu 14.04. Suddenly I couldnt search any apps through search (by pressing super key).

I used to type "Terminal" or "System Monitor" and it would display those apps. But now, when I typed "Terminal" and any other apps like Chromium, it displays "sorry no match found". How to resolve this?

I can open System Monitor by pressing Alt + F2 and using the command gnome-system-monitor.

Accidentally changed settings?

It could be that you accidentally changed the default search settings in Dash. I would check two things first:

  1. run:

    gsettings get com.canonical.Unity.Lenses home-lens-default-view
    

    This should return a list, in which applications should appear, like:

    ['applications.scope', 'files.scope']
    

    If not, you can set it to default by the command:

    gsettings set com.canonical.Unity.Lenses home-lens-default-view "['applications.scope', 'files.scope']"
    
  2. The applications Lens might be disabled for some reason, to check:

    gsettings get com.canonical.Unity.Lenses disabled-scopes
    

    It should return:

    @as [] 
    

    If not, reset it by:

    gsettings set com.canonical.Unity.Lenses disabled-scopes "[]"
    

If that doesn't work

If all fails, as an alternative, you can reset the Unity configuration as described here:

  1. You'll need Unity Tweak Tool:

    sudo apt-get install unity-tweak-tool
    
  2. Run the command:

    unity-tweak-tool --reset-unity
