Network-manager KDE no longer shows network interfaces -

[PJJ]

only an empty panel icon that declares that network-manager is not running.
And asks it to be started.

Good advice!

But how in the world do I start the network-manager.
Whatever I tried did not work. And the wireless is on and running. And so is Broadband2Go. But nothing shows.

File network interfaces (/etc/interfaces) shows standard entries
(auto lo
iface lo inet loopback).

Suggestions, PLease?

The Networkmanager is a plasma applet and you can install a second instance on for example the taskbar, would that one work better?

It is the plasma applet on the taskbar.
It is empty.
It says the network-manager is not running. That's all I get.

Trying to get the nm-applet running I get this:

"nm-applet

** (nm-applet:3044): WARNING **: Could not initialize NMClient /org/freedesktop/NetworkManager: Rejected send message, 2 matched rules; type="method_call", sender=":1.72" (uid=1000 pid=3044 comm="nm-applet ") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination="org.freedesktop.NetworkManager" (uid=0 pid=1119 comm="NetworkManager ")
** Message: applet now removed from the notification area".

[Teunis]

Hmm, usually the Network applet sits in the System Tray, not on the Task Bar.

I'm not sure what to make of the error message you intercepted, my first hunch is the '2 matched rules' hints at a conflict but it's well out of my league.

[SteveRiley]

Is Network Manager running? Let's see the output of:

sudo service network-manager status

ps -ef | grep -i network

grep -i networkmanager /var/log/syslog

[PJJ]

Thank you for the input. I have been trying to get a Wimax modem to work. In the process I apparently created a mess - including problems with permissions.

The output of your suggeste commands is as follows:

Oh, that got away from me too early. Wanted to make clear separation between the individual results.I uploaded a txt file with the results/output. don't know where it went.

[SteveRiley]

Please try the following.

1. Press Alt+F2 and type kdesudo kate /etc/dbus-1/system.d/org.freedesktop.NetworkManager.conf

2. Find the section that begins with <policy context="default">

3. You'll find several deny sections. Change the word "deny" to "allow" in the sections that include:

send_member="Sleep"/

send_member="sleep"/

send_member="wake"/

4. Save the file

5. Reboot your computer

6. Let us know if it fixes the problem.

(source)

[PJJ]

I does not.
I have a network icon in the 'hidden icon' area but it is greyed out and does not respond to anything.
Network settings under 'System Settings' are frozen at 'VPN'.

[SteveRiley]

Alright, then please revert the changes you made.

At this point, my best suggestion would be to file a bug against the Plasma Network Management widget on Launchpad. Be sure to include the output of what happens when you try to run the widget at the command prompt.

[PJJ]

Thank you for your input. the Plasma Network Management widget is apparently a source of continuing trouble judging by the number of queries on the internet. None of the suggested solutions I tried out worked so far.

I now have the widget conditionally back - provided I type "nm-applet" on a command line. Thereafter it appears among the hidden icons. However, it is greyed out and I cannot change anything on it. I am still asked to start the network manager.

peter@pHost:~$ sudo service network-manager stop
network-manager stop/waiting
peter@pHost:~$ sudo service network-manager start
network-manager start/running, process 6270
peter@pHost:~$


Now the icon is visible again, but still has no information except for a VPN connection I did not make. The error message reads:

Error displaying connection information:

No valid active connections found!

But I am running and writing this message on wi-fi.

[Teunis]

There's been a time I could not at all use this network manager because until about 2 years ago it did not fully support WPA.
At the time I was a happy user of the wicd network manager, it does require you to remove all traces of the regular network manager.

[PJJ]

I may have found one possible reason for my strange issue(s) described here and in my other post "Cannot open ControlKit...".
I attempted to speed up KDE by changing some settings. I could not make some of the changes because I am "running in failsafe mode".
Huh? I did not switch to failsafe or did I?
I may indeed have temporarily switched to failsafe because I had a problem with the Gnome keyring.

To make a long story short:
Upon attempting to log in using any other method than failsafe I receive an error message that says essentially:

"Cannot load gnome session." You are running in failsafe mode.

How do I get back to the normal log in?

I suspect that if and when I am able to log in normally again, I will also be able to get the network-manager icon back and, hopefully my network settings. The files are still there.

Should I start this as a separate thread?

[SteveRiley]

Ah! Again, since I use KDM and not LightDM, I'm kind of guessing here. Is there a button someplace you can click that will allow you to list all of the available sessions? If so, what do you see? I'm kind of surprised that you're getting an error about GNOME session.

[PJJ]

Sorry for the delayed response. Ever escalating problems of many different sort caused it, I guess.
What broke the camels back was that a flash drive that worked reliably before sudden decided to cause an error message.
Could not be read because of 'authorization' problems. I put the stick in my virtual XP and, voila, everything was there and read.

Considering the many shifting problems and issues I have experienced, there was only one reasonable decision:
Re-install 13.04.
I am doing it the hard way right now.
Going back to 12.04, upgrading to 12.10.
Then upgrade to 13.04.

All because my CD/DVD thingie does not read DVDs.

Thank you for all your assistance and encouragement.
