Ubuntu doesn't ask for my password when I'm getting out of sleep when closing my laptop and reopening it. I've followed everything listed here : Ubuntu 17.04 no longer asking for password when coming out of sleep mode but it keeps not asking my password. Moreover, the command Super + L doesn't lock the screen either. You can find below screens of my settings ( in french, sorry, but it shouldn't be difficult to understand what it corresponds to. So the options for automatic lock of the screen and locking screen when in sleep mode are activated, and the delay for locking the scren is " when screen shuts" )
Moreover, you can see here that the command
gsettings get org.gnome.desktop.screensaver ubuntu-lock-on-suspend
gives true, and
gsettings get org.gnome.desktop.lockdown disable-lock-screen
It could be related to issues I had some time ago with i3 that wasn't asking either for a password when getting into sleep mode. I remember that I tried different manips but can't remember the details. I've already removed i3 totally.
Could someone help me please ?
