Answer by WinEunuuchs2Unix for Disable password request from suspend - 18.04

For most Ubuntu distributions and versions try this in the terminal:

gsettings get org.gnome.desktop.screensaver ubuntu-lock-on-suspendtrue

If the result is true then set it to false using:

gsettings set org.gnome.desktop.screensaver ubuntu-lock-on-suspend false

Just remember to reset it before your cleaning person comes over for monthly work.
