passwordsuspendxubuntu
If I suspend my Xubuntu 12.10, and then take my computer off the suspension, it doesn't request any password. I have tried adding the gnome-screensaver on autostart settings, which I read somewhere (go to settings manager>sessions and startup>application autostarts>add [gnome-screensaver]), but that doesn't work.
How can I make my xubuntu request a password after suspension?
When you have removed xscreensaver and installed gnome-screensaver you will need to logout and login for the XFCE lock-screen menu item to work
Installing gnome-screensaver also installs gnome-screensaver-preferences.
If you run this in a terminal you will see this screen which will allow you to change from the "black screen" to one of the gnome-screensavers:
When installing gnome-screensaver it will create a file called /usr/share/applications/gnome-screensaver-preferences.desktop
To integrate this into Settings Manager then replace the contents of this file with the following:
[Desktop Entry]
Name=Screensaver
Comment=Set your screensaver preferences
Icon=preferences-desktop-screensaver
Exec=gnome-screensaver-preferences
Terminal=false
Type=Application
Categories=Settings;DesktopSettings;Security;X-XFCE
NotShowIn=KDE;GNOME;
In the file /etc/lightdm/lightdm.conf, comment out the line starting with autologin-user=.
For the record, in 'Applications Menu > System > Users and Groups' you can toggle the option 'Don't ask for password on login'. However, lightdm.conf apparently overrides this on startup. As far as I can tell, there is no way to change this through a GUI.

In Xubuntu 12.10, session is no longer locked when you Suspend, so it doesn't ask for a password on wakeup. To solve this, we need to make changes to
xfce4-sessionandxfce4-power-manager.Using Terminal Commands
Run the following commands in terminal (press Ctrl + Alt + T) to make changes to both
xfce4-sessionandxfce4-power-managerto lock the session when you Suspend:Alternatively — Using GUI
We need to make changes in both Session and Startup as well as Xfce Power Manager.
You would find both of them to be available under Settings Manager. Right Click on your Desktop and navigate through Applications → Settings → Settings Manager to open it.
Session and Startup
Open Session and Startup → navigate to the Advanced Tab → put a checkmark next to
Lock screen before sleep.Xfce Power Manager
Open Xfce Power Manager → click on Extended in the sidebar → put a checkmark next to
Lock screen when going for suspend/hibernate.Once you have made the changes, you should be asked for the password when you wakeup after Suspend.
