gnome-screensaver has been vastly simplified for major version 3 and no longer supplies the preferences dialog. It is now only useful for locking the screen and providing an unlock dialog.
I use 12.04 LTS at the moment and am able to install
gnome-screensaver version 3.4.1-0ubuntu1 and add it to the XFCE session's application autostart list.
gnome-screensaver then works when I select Lock Screen from the panel.
I am, however, unable to configure
gnome-screensaver to auto-lock the screen. There is no obvious configuration file or dialog where I can set the timeout.
Right now I use
xscreensaver to achieve auto-locking but I don't really care about screensavers, I prefer auto-lock and display suspend via DPMS. Right now
xscreensaver doesn't really play well with
lightdm on my system - user switching requires the password to be entered twice:
- user a lock-screen: press New Login
- lightdm: enter user b password
- user b xscreensaver lock-screen: enter password again
I should mention that this system was installed as Ubuntu years ago and I've been installing various
xubuntu-desktop meta-packages to try out various desktop environments.
Can anyone help me set up
