If you step away from your Ubuntu desktop for a short while it will automatically lock the screen to prevent others from accessing your files or programs. This feature is included for security reasons.

If you do not want your computer to automatically lock after a brief while, the steps below show you how to disable Ubuntu lock screen on the desktop. Below is a great place to start if you want that happen.

You can also manually lock the screen by selecting the system menu at the top right corner and clicking the lock icon on the menu pane. Doing this will lock the screen instantly. To return to your desktop raise the lock screen curtain to reveal the logon screen. Enter your password to logon.

When your screen is locked, other users can log in to their own accounts by clicking Log in as another user on the password screen. You can switch back to your desktop when they are finished.

Although this is a security feature, it can be annoying at times especially when you’re alone. The lock screen feature prevents unauthorized access. It’s very useful in public settings. But when you’re alone and no one around to access your computer, it’s probably not necessary.

So, in public settings enable the lock screen but when you’re alone and busy between different tasks away from your computer, you should probably disable and make Ubuntu less annoying.

  1. I already did this and didn’t work. I have a Lenovo laptop ideapad Flex 4 and running 18.04.2 LTS (Bionic Beaver). Whenever I close the lid or the screen locks automatically, it asks my password to unlock.

    1. I have an HP AMD® A10-8700p and it is impossible to turn off the screen lock. Additionally, it often rejects the log on with my password. Very annoying.

  2. I made the setting described here AND I turned off “dim screen” and blank screen -> never in the Power settings, but my screen STILL goes black after 10 minutes. Totally broken, thanks Gnome or whomever.
