Re: org.freedesktop.NetworkManagerSystemSettings was not provided by any .service files.

[代尔欣 <daierxin gmail com>]

Hi Dan, thanks your kindly reply.  Still have several questions bother you.

1.  For WARNING **: Icon nm-device-wwan missing: Icon 'nm-device-wwan' not present in theme
-- I use ./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc to configure both      NetworkManager and nm-applet. I think it is the correct config options.
-- Before I receive your reply, I found the /usr/share/icons/hicolor/index.theme have line:
Hidden=true
After I comment this line, the nm-applet can find those icons correctly.
-- After I receive your reply, I try your recommend:
    a. Do not comment "Hidden=true" in /usr/share/icons/hicolor/index.theme
    b. run "gtk-update-icon-cache -f /usr/share/icons/hicolor"
Also can resolve this problem.  Hmm, Just ask a question nothing to do with NetworkManager.  if have answer, save me googling^_^.  I am not familiar with gtk icon theme. what is the purpose of "Hidden=true"?

2. For WARNING **: Could not retrieve dbus connections: The name org.freedesktop.

NetworkManagerSystemSettings was not provided by any .service files.
-- After add the /etc/NetworkManager/nm-system-settings.conf. The warning gone. And I find below line from the syslog. The nm-applet also have a "Auto eth0" item now.

localhost nm-system-settings: Loaded plugin keyfile ....
localhost nm-system-settings: Adding default connection 'Auto eth0' for /org/freedesktop/Hal/devices/net_00_1e_c9_5b_a2_9e

-- But I still have a related question. From syslog, I find below line:

localhost NetworkManager: <info>  Trying to start the supplicant... 
localhost NetworkManager: <info>  Trying to start the system settings daemon... 

That info saying NetworkManager can't start the wpa_supplicant and nm-system-settings through dbus. right? 

I have to start them manually with:
wpa_supplicant -B -u &
nm-system-settings --config /etc/NetworkManager/nm-system-settings.conf &

I can add autostart script for them. But I want to know how to make NetworkManager start them automatically?

3. Regarding the polkit_context_can_caller_do_action(deprecated) and polkit_context_is_caller_authorized

If run:
pkg-config --modversion polkit 
0.9

The compile error I got:

What --prefix did you use when you installed it?  Check to be sure they
are in /usr/share/icons/hicolor.  You'll also want to make sure the GTK
icon cache is updated by doing:

gtk-update-icon-cache -f /usr/share/icons/hicolor

It may be that dbus system activation is not working correctly on your
system.  Or, see below, you probably don't have the necessary config
file for nm-system-settings.

Yeah, looks like D-Bus isn't set up correctly on your system.

Same thing; the connection editor uses the icons from the applet too.
Fixing the icon cache thing will fix this too.

You may need to create it.  It provides system-level connections to
NetworkManager, which can be used before login, and across logins.  For
your case, it should probably just contain:

[main]
plugins=keyfile

and then it should work for you.

Hmm, that should already be working correctly for you, since those calls
are already protected by checks for PolicyKit version.  Do you have the
correct PolicyKit development headers
(including /usr/lib/pkgconfig/polkit.pc) installed?  What version do you
get when you run:

pkg-config --modversion polkit
