I'm running Ubuntu 14.04. I generally have the unity launcher in auto-hide mode. Problem starts if the desktop has been locked and then unlocked. Then the unity launcher does not disappear again.

Avoid holding down the Super button.
When locking the screen with Super + L the Super key is normally held down before pressing Super. But holding down Super is in itself a shortcut to get the Shortcut Help Screen up. By using this to lock the computer, you make the sidebar reveal itself before it's "interrupted" by the screen locking. This is the reason why using Alt+Ctrl+L does not produce the same effect: none of those keys have any effect on the sidebar, dash or the Help screen.
Either rapidly tap Super+L simultaneously (DO NOT HOLD DOWN
Super
), use Alt+Ctrl+L or find a way to remove the Super shortcuts for the Dash/Sidebar.EDIT: Also found that if your sidebar gets stuck, you can tap Super twice to get rid of it.
