Gnome disabled OOTB support for managing Desktop icons, and is now handled via a gnome shell extension that is missing many features and not quite usable.
The best solution I found so far was to install nemo (file manager on Linux Mint) and make it the default instead of Gnome Files (formerly nautilus) and let it handle the desktop icons as well.
That’s it, Enjoy!

Here we will send a batch of files inside a directory to the default printer in Ubuntu.
First of all, you’d better define a default printer in your system by going to Printers and then select Use Printer by Default:
Next, just invoke the lpr command, e.g.
lpr *.pdf
That’s it, Enjoy!

If your laptop doesn’t have a working switch for turning on/off your touchpad, then this post is for you.
Create a script called disenable_touchpad.sh and add the following code to it:
!/bin/bash
state=$( gsettings get org.gnome.desktop.peripherals.touchpad send-events )
if [ "$state" == "'enabled'" ];then
gsettings set org.gnome.desktop.peripherals.touchpad send-events 'disabled' \
&& notify-send -i touchpad-disabled-symbolic "Touchpad" "Disabled"
else
gsettings set org.gnome.desktop.peripherals.touchpad send-events 'enabled' \
&& notify-send -i input-touchpad-symbolic "Touchpad" "Enabled"
fi
Mark the script as executable and move it to /usr/bin:
chmod +x disenable_touchpad.sh
sudo mv disenable_touchpad.sh /usr/bin/
Open Settings -> Keyboard, scroll to the bottom and press the + sign to assign a new keyboard shortcut:
Tested on Ubuntu 18.10, should work on any gnome-shell versions anyway!
Enjoy!
