If you’re using Ubuntu 14.10, you may want to hide all of the startup applications that are hidden by default. This can be helpful if you don’t want to see them every time you start your computer, or if you just don’t have enough space on your desktop. To hide all of the startup applications, open the System Settings application and click on the “Appearance” tab. Under “Startup Applications,” select the “All” checkbox and then click on the “Apply” button. ..
We’ve recently showed you how to manage startup applications in Ubuntu 14.04, just like you can in Windows. However, when you access the Startup Applications Preferences tool not all startup applications are listed. Some are hidden. We’ll show you how to reveal these hidden applications.
For example, these are the startup applications we see when we open the Startup Applications Preferences tool.
To show the hidden startup applications, press Ctrl + Alt + T to open the Terminal window. Type the following command at the prompt and press Enter.
NOTE: Copying and pasting the above command would be easier and ensure accuracy.
Type the password when prompted and press Enter.
To open the Startup Applications Preferences tool, click the Search button at the top of the Unity bar.
Start typing “startup applications” in the Search box. Items that match what you type start displaying below the Search box. When the Startup Applications tool displays, click the icon to open it.
You will now see all the startup applications that were previously hidden. Make any changes you want and click Close to close this tool.
To not display the hidden startup applications again, type (or copy and paste) the following command at the prompt and press Enter.
To close the Terminal window, click the X in the upper-left corner of the window, or type “exit” (without the quotes) and press Enter.
