Ubuntu – How to restore accidentally removed Launcher icon for external drive in Unity

drivelauncherportableunity

Ubuntu 14.04 LTS 64-bit: I used to get an icon for my portable drive on insertion. I have accidentally lost this by clicking on 'Unlock from Launcher' instead of 'Eject'. Now this icon does not appear when the drive is connected. How do I restore the original behaviour?

Best Answer

1. Command line:

You can do that by the command:

gsettings set com.canonical.Unity.Devices blacklist "[]"

Explanation

By removing the icon from the launcher, you blacklisted the device from the launcher. With the command above, you "empty" the blacklist.

If you want to to have a more selective way to set which device to keep in the launcher, first run:

gsettings get com.canonical.Unity.Devices blacklist

The output will be like:

['<device_1>', '<device_2>']

To restore device_1 in the launcher:

gsettings set com.canonical.Unity.Devices blacklist "['<device_2>']"

2. GUI

Alternatively, you can restore your icons with dconf-editor. You might have to install it first:

sudo apt-get install dconf-editor

(Or simply install it via Software-Center)

Then open the editor, browse to: com > canonical > unity > devices:

Then you can either set the blacklist to "default" settings (which is none), or remove devices from the blacklist selectively.
