To make Discord messages pop up on your screen, turn on desktop notifications in Discord and in your device’s notification settings. For DMs or server messages, you may also need to allow notifications for that specific server or channel, and make sure Do Not Disturb is off.

On PC or Mac

  1. Open Discord and click the gear icon for User Settings.
  2. Go to Notifications.
  3. Turn on Desktop Notifications.
  4. Set message alerts to All Messages or Only @mentions , depending on what you want.
  5. In Windows or macOS notification settings, allow Discord to show banners/alerts.

On mobile

  1. Open Discord.
  2. Tap your profile icon, then Settings.
  3. Open Notifications.
  4. Turn on notifications and choose your alert preferences.
  5. In your phone’s settings, make sure Discord notifications are allowed and banners/lock-screen alerts are enabled.

If it still does not pop up

  • Check that the server or channel is not muted.
  • Make sure you are not already viewing that DM or channel, since some alerts won’t appear while the chat is open.
  • Turn off Do Not Disturb on your device.
  • Restart Discord or your phone/computer after changing settings.

Useful detail

If you mean messages appearing as floating bubbles or chat heads , Discord does not generally offer a built-in “bubble” mode like that on mobile; what you usually get are standard push notifications and banners.

TL;DR: Enable Discord desktop/mobile notifications, allow them in your system settings, and unmute the relevant server or channel.
