LightDM - Sep 2011 - Triggering LightDM's lockscreen or user switcher

Hello,

I am working on integrating a few DM's into XFCE's logout button.
I've found commands to lock GDM and XScreensaver:

    gnome-screensaver-command -l

And:

    xscreensaver-command -lock

Is there a similar way to lock the screen (and maybe switch to the user
selection dialog) with LightDM?

Thank you!

Shouldn't you use xdg-screensaver or xflock4?

Locking the screen is not really a lightdm feature. Switching user is
supported through a gdmflexiserver but it's not really in the PATH so
you would need to try both the gdm and lightdm path.

We use the following modification to gdmflexiserver to lock the
screen before switching users on openSUSE:
https://build.opensuse.org/package/view_file?file=lightdm-lock-screen-before-switch.patch&package=lightdm&project=X11%3Axfce&srcmd5=4fd8b507ca5e29e2fa9c5edb483f12b8
Apart from xscreensaver and gnome-screenserver it also works
with the KDE screensaver slock and xlock/xlockmore.

Thank you everyone for the input.

I managed to hack together a patch (that actually works), so I used xflock4 and
gdmflexiserver to accomplish both of those tasks.

Thank you once again!
Nikita
