I am having trouble getting NetworkManager to start per the following. Any ideas what causes "Error getting login monitor"

Code:
T410S warren # NetworkManager --no-daemon
NetworkManager[14826]: <info> NetworkManager (version 0.9.8.10) is starting...
NetworkManager[14826]: <info> Read config file /etc/NetworkManager/NetworkManager.conf
NetworkManager[14826]: <info> WEXT support is enabled
Error getting login monitor: -2

What about using DHCPCD instead of NetworkManager?

I actually have NetworkManager compiled with dhcpcd use flag and have dhcpcd installed. When it runs, NetworkManager manages dhcpcd to configure connections. It is not set to load at boot, which allows Networkmanager to do its job.

What is the benefit oft using troublesome networkmanager along with dhcpcd instead oft just dhcpcd?

I have it running on other machines and like the nm-applet interface in kde.

Your error message says some file is missing? Gould you check in one oft the non-trouble installations to which package it belongs? Then compare that package on both machines.

It turned out to be a problem connecting to dbus. I had dbus compiled with the systemd profile set but I want to keep an openrc system.

I set the profile to non-systemd and then recompiled the essential packages. Now it connects as it should.

dhcpcd-qt port is in progress :)
dhcpcd-gtk already works fine. You can find that in the dhcpcd-ui package in portage.

I think I have something similar now; NetworkManager will not start. But I don't get any real information from it;
Code:
NetworkManager --no-daemon --log-level=DEBUG

(NetworkManager:23976): GLib-WARNING **: (/var/tmp/portage/dev-libs/glib-2.40.2/work/glib-2.40.2/glib/gerror.c:381):g_error_new_valist: runtime check failed: (domain != 0)


I tried to rebuild NetworkManager and I get some information about Systemd, which i have never used/installed on this machine;

Code:

 * Messages for package net-misc/networkmanager-0.9.10.0-r1:

 *
 * You seem to use 'ifnet' plugin in /etc/NetworkManager/NetworkManager.conf
 * Since it won't be used when running under Systemd, you will need to stop setting
 * ifnet plugin there to allow NetworkManager to work.
 


Looking in var/log/messages, I get this;
Code:

Since I have never messed with systemd, I don't know what to look for. Useflags has -systemd when trying to reemerge dbus.

Can you bring up the wlan0 interface manually? I am wondering if there is a iwlwifi driver issue.

Yes, if I start it using the init script, it looks alright - driver seams fine.

I am affected by the same issue, i don't use systemd and my dbus doesn't have systemd flag enables, my profile is default/linux/amd64/13.0/desktop/kde

I have just added -systemd to global useflag, and emerge just says nothing to merge, so it seems no packages are using systemd on my system



----Edit----

Solved editing /etc/NetworkManager/NetworkManager.conf removing ifnet plugin

[main]
#plugins=ifnet,keyfile
plugins=keyfile
