If you are getting problem with the auto-hide feature of the Unity Launcher, you can use the Super key. The Super key reveals the sidebar. You can just tap Super twice if the sidebar gets stuck. You can also tap Super + L or Alt+Ctrl+L to lock and unlock the system.
If the above step doesn’t solve the problem, try re-installing or upgrading the Unity. To do so, open the Terminal and run the following command:
sudo apt-get upgrade unity
sudo apt-get update && sudo apt-get upgrade
