Hide icons from Gnome launcher applications page in Fedora 26

Question

We are trying to hide application icons from the Gnome launcher. Note, this is not the Dash panel on the left, this is when you click the Applications icon in the dash panel and it shows you all the applications.

I have tried the following (with a reboot in between each (wayland won't allow restarting of gnome)):

• add NoDisplay=True to the end of /usr/share/applications/app-name.desktop
• add Hidden=True to the end of /usr/share/applications/app-name.desktop
• copied those .desktop files to ~/.local/share/applications
• disabled Search in gnome-control-center
• mv /usr/share/applications/*.desktop /another/directory (system won't boot)
• installed and tried alacarte

The problem with moving the desktop items is that the system relies on these files during boot. Also, the gnome-control-center relies on the sub-component *.desktop items existing in /usr/share/applications. I am assuming this has something to do with the new Wayland display system replacing X11, but am not sure. Thanks.

Answer 1

The True should be lowercase. Adding this line works for me:

NoDisplay=true

Should work for both ~/.local/share/applications/app-name.desktop and /usr/share/applications/app-name.desktop.

Also, you can hide the entry only for a specific desktop by adding NotShowIn=desktop-name, as mentioned in the arch wiki.
