Upon pressing the
Print Screen key, bell sound is heard, instead of taking a screenshot. I have
gnome-screenshot installed on my device.
Most likely, the PrintScreen key is associated with copying the screenshot to the clipboard. So, you need to paste the image from the clipboard to any application which supports images.
If you want to change this behaviour, launch Settings, go to Keyboard shortcuts. Look for the screenshots section. See whether the PrintScreen key has been associated with any action or not. If not, click on Save a screenshot to Pictures and set it to the PrintScreen key.
