Files and folders in the Desktop disappeared

It's quite like this question. But there is a little bit difference.

In my situation, all files and folders in the Desktop were disappeared. And when I right clicked on the desktop, the drop-down box didn't appear. Whatever operation I did, nothing happened.

But when I opened the home folder, and access the desktop folder from it, files and folders were there. And I could operate the files as usual.

So I wonder how to get my files and folders back to the Desktop.

Thanks to @green7. His answer here helps me solve the problem.

First of all, I'm sure my ~/.config/user-dirs.dirs isn't changed.

Second, restart nautilus.

1. run the command in the terminal: killall nautilus or nautilus -q

2. press Alt+F2, search nautilus and run it.

I have encountered the same problem in my Ubuntu 16.04 LTS desktop. This is how I could rectify the issue.

• Go to Gnome Tweak Tool(Install it if not installed already).
• Choose "Desktop" from the left sidebar
• Toggle "Icons on Desktop" option to "ON"
