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?

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-session and xfce4-power-manager.

Using Terminal Commands

Run the following commands in terminal (press Ctrl + Alt + T) to make changes to both xfce4-session and xfce4-power-manager to lock the session when you Suspend:

xfconf-query -c xfce4-session -p /shutdown/LockScreen -s true

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 ApplicationsSettingsSettings Manager to open it.

xubuntu settings manager navigation

  1. Session and Startup

    Open Session and Startup → navigate to the Advanced Tab → put a checkmark next to Lock screen before sleep.


  2. 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.

The first didn't work, because it said the file didn't exist and I had to create is using the --create option, but the second option (GUI) did work! Thanks so much! –  Martinio Feb 21 '13 at 15:22
I followed the GUI part and it worked. Thanks. –  chapagain May 10 '13 at 15:38
