How to Enable or Disable Visual Alerts in Ubuntu Linux

This article explains the steps you can take to turn on or off visual alerts on Ubuntu Linux.

Your Ubuntu Linux computer by default will play a sound when you get a user or system alert. System alerts are there to notify you when something is wrong or when an event occurs.

You can enable the visual alerts feature in Ubuntu Linux if your computer doesn’t have a sound card to play audio when an alert occurs. With visual alerts, you can choose to have the entire screen or your current window visually flash whenever the alert sound is played.

This might also come in handy when the system sound is disabled or the volume is turned off so you don’t disturb others in quiet environments, like a library.
