How to replace Gnome 3.4 Screensaver with Xscreensaver

Postby maxibuntu on Sun Dec 09, 2012 9:03 am

The Gnome 3 screensaver is nothing compared to Xscreensaver so I replaced it.

All the following commands can be run from a Terminal, like for instance gnome-terminal. You can easily select and copy a command from this page, then paste it in a terminal, and hit enter.

I have a sudo setup on LMDE, if you have an su setup like on standard Debian, use:

Code: Select all
su -

...and enter the root password, and commands.

But we will continue with the sudo version:

Remove Gnome Screensaver and install Xscreensaver:

Code: Select all
sudo apt-get remove --purge gnome-screensaver
sudo apt-get install xscreensaver

Remove old autostart entry for gnome-screensaver.

Code: Select all
rm -fv ~/.config/autostart/gnome-screensaver.desktop

Create a link gnome-screensaver-command > xscreensaver-command to enable screenlocking with Crtl-Alt-L.

Code: Select all
sudo ln -fs /usr/bin/xscreensaver-command /usr/bin/gnome-screensaver-command

Put the following code in ~/.config/autostart/xcreensaver.desktop by running:

Code: Select all
gedit ~/.config/autostart/xcreensaver.desktop

Then copy/paste the following code in gedit and save the file.

Code: Select all
[Desktop Entry]
Name=Screensaver (xscreensaver)
Comment=Start screensaver
Exec=xscreensaver -no-splash

You can of course also do this with gnome-session-properties, but if you also run XFCE be sure to edit the xscreensaver.desktop file to contain NotShowIn=XFCE; . That is because XFCE starts Xscreensaver from /etc/xdg/xfce4/xinitrc and not with an autostart xscreensaver.desktop file.

Now there's one thing left: To make the "Lock screen" menu entry in Gnome 3 work, we have to create a file /usr/local/bin/ with the following content:

Code: Select all
sudo gedit /usr/local/bin/

Paste the following code in gedit, and save the file.

Code: Select all
# Make the Gnome 3 screenlock menu entry work with xscreensaver and dbus
# Call this script with an autostart entry from ~/.config/autostart/
import dbus
import dbus.service
import dbus.glib
import gobject
import os
class ScreenDbusObj(dbus.service.Object):
    def __init__(self):
        session_bus = dbus.SessionBus()
        dbus.service.Object.__init__(self,bus_name, '/org/gnome/ScreenSaver')
    def Lock(self):
        os.system( "xscreensaver-command -lock" )
if __name__ == '__main__':

Make the file executable:

Code: Select all
sudo chmod +x /usr/local/bin/

Finally, add an autostart entry in ~/.config/autostart/xscreensaver-dbus-screenlock.desktop with the following content:

Code: Select all
gedit ~/.config/autostart/xscreensaver-dbus-screenlock.desktop

Paste the code in gedit and save.

Code: Select all
[Desktop Entry]
Name=Xscreensaver Lock Screen
Comment=Make Xscreensaver screenlocklock work with Gnome 3 menu

Thanks for this how-to, it worked well on my Mint 14 (64bit with Cinnamon) :)

I haven't had any luck with getting xscreensaver to use Pictures folder slideshow. Nevertheless, the screensaver app that I've found to work as good as the Gnome 2 screensaver (and just as easily) is the Mate Screensaver (see screenshot).
