Can't find .config folder in Ubuntu 14.04?
Generally any .folder are hidden folders
.config is a hidden folder under home. You can view hidden files in any folder View--> Show Hidden Files or Ctrl + H
Since .config is a hidden folder it will not appear in your File Manager by default. To be able to view it, open your home folder and press Ctrl + H. It will show all the hidden folders in your home directory.
To hide the folders, press Ctrl + H again.
