1. Left-clicking on the Indicator Systemtray Unity icon - in this case, the tray icons will be displayed under it:
You can move the icons horizontally by scrolling on the Indicator Systemtray icon on the Unity panel. Moving the icons to the left of the indicators like in the screenshot above is a bit tricky because once the icons are on top of Indicator Systemtray, you won't be able to scroll on it any more, but you can change this via dconf-editor (see below).
sudo apt-get install dconf-editor
Note that if you use multiple monitors, the tray will only show up on the primary monitor!
Install Indicator Systemtray Unity in Ubuntu
