Why does my screen go dim after a while?

If it is possible to set the brightness of your screen, it will dim when the computer is idle in order to save power. When you start using the computer again, the screen will brighten.

To stop the screen from dimming itself:

  1. Open the Activities overview and start typing Settings.

  2. Click on Settings.

  3. Click Power in the sidebar to open the panel.

  4. Switch Dim screen when inactive to OFF in the Power Saving section.
