Can't Change User from Lockscreen, Ubuntu 16.10

  • 772

I have a fresh install of Ubuntu 16.10, with two users set up. If I lock the screen when I am logged in (either manually or through inactivity), there is no way for the other user to log in. The buttons in the top menu do nothing, and only my name shows on the screen.

    Seems you have Gnome's user-switching option disabled.

    You can check this running gsettings get org.gnome.desktop.lockdown disable-user-switching, which should return true if its disabled.

    Maybe it has been disabled from Unity Tweak Tool, dconf-editor, or other tweaking tool. Anyway you can restore that functionality in a couple of ways (or more).

    Changing user-switching from terminal (gsettings)

    • You can enable the user-switching option again running:

      gsettings set org.gnome.desktop.lockdown disable-user-switching true

    • To disable it again simply run:

      gsettings set org.gnome.desktop.lockdown disable-user-switching false

    Changing user-switching from GUI (dconf-editor)

    If you prefer GUI tools for this kind of tasks, you can use dconf-editor. If you don't have it yet on your system, you can install it running sudo apt install dconf-editor.

    • Open dconf-editor from Unity's dash.
    • Navigate to org.gnome.desktop.lockdown on the left pane.
    • Click the disable-user-switching item on the right pane.
    • Change its value (true/false) from popup window and hit save button.

    Personally, I prefer to keep it disabled (for security reasons) on systems without such requirements (Examples: one user only, no need for fast user switch, etc...).

    Hope it helps.

    You can **disable** the user-switching option by running:

gsettings set org.gnome.desktop.lockdown disable-user-switching true

To **enable** it again simply run:

gsettings set org.gnome.desktop.lockdown disable-user-switching false
