Completely remove lockscreen

  • 772

I have the vanilla Ubuntu 18 installed on a computer and I'd like to completely disable the lockscreen. But even after disabling it in the settings (see image) it still shows up after "waking" up from the screensaver (blak screen), you just don't have to enter the password anymore. Is there a way to actually completely disable it such that it also doesn't show up after coming back from the screensaver (I'd like to keep the blank screen as screensaver)?

    Enable/Disable Lock Screen.

    To disable Lock screen using GUI, just follow this:

    Settings -> Privacy -> Screen Lock -> change 'Automatic Screen Lock' to 'Off'

    enter image description here

    Figure-1: Disable screen lock using Settings GUI

    To disable Lock screen through command line permanently, issue the following commands:

    $ gsettings set org.gnome.desktop.screensaver lock-enabled false
$ gsettings set org.gnome.desktop.lockdown disable-lock-screen true

    enter image description here Figure-2: Disable screen lock and "Screen Lock window" is also made inaccessible

    The first command disables Screen Lock (refer small red box in figure-2). The second command makes Screen Lock window permanently inaccessible and no body can touch it even through Settings GUI (refer large red box in figure-2).

    If you are unhappy with the new setting, you can reverse it using following command:

    $ gsettings set org.gnome.desktop.screensaver lock-enabled true

    enter image description here Figure-3: Enables screen lock but "Screen Lock window" is still inaccessible

    This command enables Screen Lock again (refer small red box in figure-3). Note that the Screen Lock window is still inaccessible (refer large red box in figure-3).

    To enable Screen Lock window access by Settings GUI

    $ gsettings set org.gnome.desktop.lockdown disable-lock-screen false

    enter image description here Figure-4: The "Screen Lock window" is now accessible

    After the execution of command, the Screen Lock window is now accessible through Settings GUI (refer large red box in figure-4).

  2. I had a similar problem with it going bland when ALL Possible Settings for this had Lock or Screen saver or timeout set to NEVER.

    Screen Going into SLEEP MODE, or BLACK, when NOT set to!

    $ gsettings set org.gnome.settings-daemon.plugins.power idle-dim false

$ gsettings set org.gnome.desktop.screensaver lock-enabled false

$ gsettings set org.gnome.desktop.lockdown disable-lock-screen true

    To make this permanent, you need a gsettings override file...

    1. Open a new empty document in gedit, (or other text editor) on your host system.

    2. Add the following contents to your file:

      [org.gnome.desktop.screensaver]
lock-enabled = false
[org.gnome.settings-daemon.plugins.power]
idle-dim = false

    3. Save the file with the following name:

      90_ubuntu-settings.gschema.override

    4. Move it to the right location (and give root privileges and executable):

    5. Open Nautilus (or another file browser) on your host system WITH/AS ROOT, and navigate to the directory where you saved the file 90_ubuntu-settings.gschema.override. Cut and Paste it to:

      /usr/share/glib-2.0/schemas/

    6. Activate it in terminal:

      $ sudo glib-compile-schemas /usr/share/glib-2.0/schemas/

    I sure hope this helps others, Mark
