Ubuntu: How to reset DND on startup

In Ubuntu, I often use the "Do Not Disturb" feature to disable notifications and then forget to turn it off.
DND stays enabled across reboots, but I usually want it to be switched off the next day.

Here is how to reset it for each session:

1. Press the Super ("Windows") key to open Gnome's app launcher.
2. Search for "Startup Applications" and launch it.
3. Press the "Add" button on the right, and fill in:
   • Name (Example): Turn off DND
   • Command: gsettings set org.gnome.desktop.notifications show-banners true
4. Click "Add" to save. You can then close the "Startup Applications" window. The next time you log on, DND will be turned off.
