Every time I connect an external disk with an encrypted partition a fullscreen pop up dialog appears:

Enter a passphrase to unlock the volume

I usually do not want to decrypt this partition so the message is disrupting.

I am using Ubuntu 19.04 and GNOME Shell 3.32.1.

In Settings > Devices > Removable Media I have "Never prompt to start programs on media insertion" checked, but the pop up still appears.

How can I prevent these dialogs?

Edit: An answer below explains how to disable automount altogether. This is an improvement, though I would ideally like to enable automount and not decrypt encrypted volumes by default.

  • Perhaps you can clarify a bit. You have to decrypt it before you can use it. If you don't plan on using it why would you plug it in? – WinEunuuchs2Unix Dec 21 '19 at 19:38
  • It is a disk with multiple volumes. Only one on encrypted. – Ian Mackinnon Dec 21 '19 at 19:40
  • Got it, so the real question could be "how to only auto-mount unencrypted partitions"? – WinEunuuchs2Unix Dec 21 '19 at 19:54

I got this working in Ubuntu 18.04, so hopefully this will translate to 19.04:

Run dconf-editor and search for automount. You will see (2) settings, both under /org/gnome/desktop/media-handling: automount and automount-open. Switch automount to off.

If you need to mount these devices, you can always go into Disks and mount them from there.

  • Thanks. I used the command line version gsettings set org.gnome.desktop.media-handling automount false and it does just what it says :) – Ian Mackinnon Dec 20 '19 at 14:02
