How to Disable Ubuntu 17.10 Lock Screen

e commerce 1606962 640

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.

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.

Ubuntu lock screen is good, however, it can be annoying at times. If you’re not concern about security and which to turn of the lock screen, continue below to learn how to.

To disable Ubuntu lock screen, click the system menu at the top right corner and select Setting.

Then select Privacy on the left menu and show the privacy options. On the privacy pane, select Screen Lock

Exit and you’re done. You computer will never lock its screen again when it is idled.


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. Thank you!
    Still adjusting to U17.10, but it’s a pleasure to work with! 😉

  2. I originally hid the lock screen, after 17.10 its showing up again, even though my setting is still off. Very annoying. I’ve also tried changing some flags as recommended through google searching.

  3. Disabling doesn’t work. It has no effect at all.

  4. I am NOT enjoying 17.10 and this locking issue is just ONE of the reasons why. This does not work at all.

    1. I feel like; this is a test.
      How much time is wasted?
      Searching to locate, in never used op system Len ix.
      Most annoying feature? then finally supposed locate were you can turn it off. I hope it works Ive been looking in my spare time since i installed.
      Little too cruel for me , inflicting so much torment and distraction upon someone learning.
      Test your patience, stay calm headed and move forward. You will complete your task
      I am dis appointed please fix.

  5. Hey, good for you, you are keeping my cat from reading my files while I am out of the room, you locked my computer. Ubuntu just lost another user. Same problem, same lack of a cure, same as last time I tried Ubuntu. Kubuntu is plagued with same need to change, change colors, change fonts, change menus, change cursors, change usability to less usable, drive away users.
    I could go on but instead I am gone to find another distro.

  6. Hi,
    I’m not sure, if this is the right place – I just try it.
    When my System boots up (Ubuntu 17.10 – Mate Desktop, which is great!) the Log In screen freezes for a while – up to 3..4 minutes. After this “delay-time” I am able to enter Log In creds.
    I tried it with another user / admin … always the same issue.
    Any ideas?

    Thanks in advance for your/any reply

  7. Disabling it doesnt work…… seriously annoying.

  8. Annoyed Ubuntu User

    Lol “Exit and you’re done. You computer will never lock its screen again when it is idled.” Not true in my case and I still have no idea why.

    I’m running Ubuntu 17.10 in a VM (I installed it only last week so its a clean install with very little configuration changes. I have switched Screen Lock OFF, but it still locks.

    Is there some other processes that can invoke the screen lock?

  9. Same problem here. In vmware 12, ubuntu 17.10 has it’s options for changing screen lock greyed out.

  10. Keep in mind if you’re using a VM, that pressing Windows+L will lock the VM as well as your windows machine. This is what happened to me, not sure if that’s what happened to some of you, too.

    This doesn’t work. Closing the screen still causes ubuntu to lock

  12. Ubuntu 18.04.03, screen coming back from sleep, I DO have screenlock OFF, however I get a sort of curtain, with animated arrows bottom to top indicating the it will shift up and free the screen if I click on it… PLEASE HOW CAN WE GET RID OF IT? It is 1) Unuseful 2) SLOOOW, it often takes various seconds before reacting and not so seldom it requires clicking / pressing the space bar for as long as two minutes. PLEASE CAN WE GET RID OF THIS THING ASAP?
