This is what I have tried so far:

$ sudo apt-cache search lightworks  
lightworks - Hollywood-strength editing for everyone  
$ sudo apt-get --purge remove "lightworks - Hollywood-strength editing for everyone"  
Reading package lists... Done  
Building dependency tree         
Reading state information... Done  
E: Unable to locate package lightworks - Hollywood-strength editing for everyone

Ubuntu Software Center can't find lightworks.

Syntax for removing a package with its configurations is:

sudo apt-get purge [Package name]


sudo apt-get --purge autoremove [Package name]

So run :

sudo apt-get purge lightworks


sudo apt-get --purge autoremove lightworks

The section, Hollywood-strength editing for everyone is a description about software. Not the package name.

I think you manually installed lightworks from .deb file.

How to uninstall a .deb package?
