In a standard install of Ubuntu, the default behaviour of the file manager Nautilus is not to show hidden files. Nothing new here – it’s the same with Windows. At least with Nautilus, the way to show hidden files is a bit easier to find. When you go the the View menu, you will see you can select Show Hidden Files.
But if you find that after logging in again you’re back to square one, it’s because that method was actually temporary, so this is what you need to do:
Go to Edit > Preferences, and in the first View tab, select Show hidden and backup files.
All hidden files and folders will start with a . (period), and be listed after your normal files and folders.
