Docky, like Plank or Cairo Dock, is an advanced shortcut bar that sits at the edges of your screen. It provides easy access to some of the files, folders and applications on your computer, displays which applications are currently running, holds windows in their minimized state and more.

Install or remove Docky in Linux Mint Installing Docky sudo add-apt-repository ppa:docky-core/stable sudo apt-get update sudo apt-get install docky From Terminal: Removing Docky sudo apt-get remove --purge docky && sudo apt-get autoclean && sudo apt-get autoremove From Terminal: Optional: Delete Docky PPAs and Authentication key in Software Sources





It happens that System Settings icon is incorrectly displayed as “Bluetooth” in Docky for Linux Mint users (at least in the Cinnamon edition).

Next, I’ll give you some tips on how to correct this visually odd glitch. Hopefully it will help you not only with the System Settings icon but with any other application icon wrongfully represented in Docky. Let’s get down to it

Straight to the point

In Terminal:

sudo killall docky sudo cp /usr/share/applications/cinnamon-settings.desktop /usr/share/applications/cinnamon-settings.desktop.`date +"%m_%d_%Y"` sudo sed '/Keywords=/a\StartupWMClass=Cinnamon-settings.py' -i /usr/share/applications/cinnamon-settings.desktop rm ~/.cache/docky/docky.desktop.*.cache

Now launch docky once again and enjoy your System Settings icon

What was done

1- Close Docky:

sudo killall docky

2- Make a backup copy of /usr/share/applications/cinnamon-settings.desktop. This is the file we worked with.

sudo cp /usr/share/applications/cinnamon-settings.desktop /usr/share/applications/cinnamon-settings.desktop.`date +"%m_%d_%Y"`

…and make sure the backup copy is there 😉

ls -la /usr/share/applications/cinnamon-settings.desktop* $-rw-r--r-- 1 root root 11022 Jan 8 08:36 /usr/share/applications/cinnamon-settings.desktop $-rw-r--r-- 1 root root 11022 Jan 8 08:40 /usr/share/applications/cinnamon-settings.desktop.01_08_2016



3- Edited cinnamon-settings.desktop adding StartupWMClass=Cinnamon-settings.py attribute so that Docky can match its icon.

sudo gedit /usr/share/applications/cinnamon-settings.desktop

4- Clear current user Docky cache

rm ~/.cache/docky/docky.desktop.*.cache

That’s all!

Fixing Docky Icons

If you ever come across an icon in Docky not being properly displayed, here is a way to correct it.

1- Get the WM_CLASS property from the application window. In Terminal:

xprop | grep WM_CLASS | awk '{print $4}' Press < 'Enter'> and click the window you want to get the WM_CLASS from. Take note of the output

For example, System Settings WM_CLASS is “Cinnamon-settings.py” (see screenshot above), which is the value we used as StartupWMClass attribute, as explained in step #3.

2- Edit its corresponding .desktop file under /usr/share/applications as we did with cinnamon-settings.desktop.

3- Close Docky, delete its cache files and launch it again.
