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
Type=Application
Icon=preferences-desktop-screensaver
TryExec=xscreensaver
Exec=xscreensaver -no-splash
NotShowIn=XFCE;KDE;
Hidden=false
X-GNOME-Autostart-enabled=true
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/xscreensaver-dbus-screenlock.py with the following content:
- Code: Select all
sudo gedit /usr/local/bin/xscreensaver-dbus-screenlock.py
Paste the following code in gedit, and save the file.
- Code: Select all
#!/usr/bin/python
# 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()
bus_name=dbus.service.BusName("org.gnome.ScreenSaver",bus=session_bus)
dbus.service.Object.__init__(self,bus_name, '/org/gnome/ScreenSaver')
@dbus.service.method("org.gnome.ScreenSaver")
def Lock(self):
os.system( "xscreensaver-command -lock" )
if __name__ == '__main__':
object=ScreenDbusObj()
gobject.MainLoop().run()
Make the file executable:
- Code: Select all
sudo chmod +x /usr/local/bin/xscreensaver-dbus-screenlock.py
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]
Type=Application
Name=Xscreensaver Lock Screen
Comment=Make Xscreensaver screenlocklock work with Gnome 3 menu
TryExec=xscreensaver-dbus-screenlock.py
Exec=xscreensaver-dbus-screenlock.py

Hidden=false
