After the install of 14.04 i discovered light-locker &
light-locker-settings, which do not work. This is the error-msg:

~$ /usr/bin/light-locker-settings

** ( WARNING **: Couldn't connect to
accessibility bus: Failed to connect to socket /tmp/dbus-B0qCyeoOWY:

Traceback (most recent call last):
line 552, in <module>
    main = LightLockerSettings()
line 97, in __init__
line 249, in init_settings
    if self.check_running_process("xfce4-session"):
line 195, in check_running_process
    p = psutil.Process(pid)
  File "/usr/lib/python2.7/dist-packages/psutil/", line 232,
in __init__
    raise NoSuchProcess(pid, None, 'no process found with pid %s' % pid)
psutil._error.NoSuchProcess: no process found with pid 27881

Now, i've a question: Is there any need for light-locker, when i'm
running xscreensaver? And in this context: Is xfce-power-manager needed
together with fglrx and xscreensaver. I'm under the impression, the
settings set in xscreensaver "overrule" xfce-power-manager (?)
