I have just migrated from Ubuntu 10.04 to 12.04. As most of the UI elements have been changed I don't know to add Force quit icon, which is needed for most of the not responding applications. So, how to add force quit icon in ubuntu 12.04?

In the terminal, run these commands:

  1. wget

    (If the contents of the URL above are not accessible, see the Reference section below.)

  2. mv Force_Quit.desktop ~/.local/share/applications/
  3. nautilus ~/.local/share/applications/

Now in the window that popped up, drag Force_Quit.desktop to the Unity launcher.

xkill will now be invoked every time you click on the new launcher icon.

If you do not have Internet access, the contents of is saved here:

[Desktop Entry]
Name=Force Quit
Comment=Force Kill an Unresponsive Running Application or Window

You can write the contents to Force_Quit.desktop by making the file with the command gedit ~/.local/share/applications/Force_Quit.desktop.

Why these much steps needed in Ubuntu 12.04. I did with a single click in 10.04. Is there any easy way for that? - @Deltik – arulappan Aug 1 '12 at 17:21
I created a new file in the name of ForceQuit.desktop. But I couldn't open the file to copy the provided content. It says, "There was an error launching the application." – arulappan Aug 1 '12 at 17:28
I opened the file via gedit and pasted the content. Finally, I got the Force Quit functionality. – arulappan Aug 1 '12 at 17:32
I edited the answer to make it easier to follow. – Deltik Aug 1 '12 at 17:33
Your previous solution can be followed by even those who don't have the internet connection to access - @Deltik – arulappan Aug 1 '12 at 17:36

A far easier way is to simply head over to your keyboard shortcuts, add a custom one to let's say F11, name it something like "Kill non-responsive windows" and with the command used xkill.
