Description Michael S. Tsirkin 2015-09-10 08:12:26 EDT
Description of problem:
light locket (screen locker for light dm)
crashes whenever I start it.
nturally, it also can't lock screen.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. install xfce group and light-locker
2. login in xfce session
3. run: light-locker

Actual results:

** (process:25039): WARNING **: Schema "apps.light-locker" not found. Not storing runtime settings.
process 25039: arguments to dbus_message_new_method_call() were incorrect, assertion "path != NULL" failed in file dbus-message.c line 1340.
This is normally a bug in some application using the D-Bus library.
  D-Bus not built with -rdynamic so unable to print a backtrace
Aborted (core dumped)

Expected results:
locker should start, not crash

Please RTFM how this component is meant to work. After installation of light-locker, you have to logout and login to get the service running.

$ light-locker-command -l
→ locks screen


After installing light-locker, it will auto start along your session and you will be able to lock your session with "light-locker-command -l".
This will redirect you to VT8 (assuming that your open session was on VT7 and is now kept safe by light-locker) and present LightDM's greeter for unlocking your session again.
On suspend/resume light-locker will lock the active session and redirect to the LightDM's greeter for unlocking the session again.
There is no support for gnome-settings-daemon in order to keep things slim, so you might have to add a custom keyboard-shortcut for this to work.
light-locker will automatically lock the session shortly after the X11 screen saver kicks in. The timeout can be set with --lock-after-screensaver. With xset the X11 screen saver can be adjusted.
Use --late-locking to avoid some of the negative effects of VT switching. This will lock the session on the deactivation of X11 screen saver instead of activation.
light-locker will automatically lock the session on suspend/resume. To disable this behaviour with --no-lock-on-suspend.
