Ubuntu – Annoying dock in Ubuntu 17.10

In Tweak Tool > Extensions > Dash to Dock > [little gear icon settings thing] > Behaviour, you can customise what the Click and Shift+Click actions do for any icon in the dock.

I found a way to do that:

1. Open a terminal and install wmctrl:

   sudo apt-get install wmctrl
   

2. Create a shell script named show-desktop.sh (I put it in my home folder)

   gedit ~/show-desktop.sh
   

   place this code in there:

   #!/bin/bash
   status="$(wmctrl -m | grep "showing the desktop" | sed -r 's/(.*)(ON|OFF)/\2/g')"
   
   if [ $status == "ON" ]; then
       wmctrl -k off
   else
       wmctrl -k on
   fi
   

   and make it executable:

   chmod +x ~/show-desktop.sh
   

3. Create a file show-desktop.desktop in ~/.local/share/applications/ folder:

   gedit ~/.local/share/applications/show-desktop.desktop
   

   Add this text and save (don't forget change the value on <your user>):

   [Desktop Entry]
   Type=Application
   Name=Show Desktop
   Icon=user-desktop
   Exec=/home/<your user>/show-desktop.sh
   

4. Open the dash, search for show desktop and add it to the favorites.
