Disable NetworkManager (starts after every boot)

Hello all,

NetworkManager is being started after every boot and I dont know how or why. I disabled it via systemd (systemctl disable NetworkManager) and its disabled, but it still starts after every boot.

My question is: How can I find out how a process is started? How can I even debug this problem?

Thanks

Re: Disable NetworkManager (starts after every boot)

look at the output of pstree.  It should show you what started it. And what started that which started it...

Re: Disable NetworkManager (starts after every boot)

Thanks. It says that its started via systemd.... right?!

systemd-+-NetworkManager-+-{gdbus}
        |                `-{gmain}
 

and:

● NetworkManager.service - Network Manager
   Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; disabled; vendor preset: disabled)
  Drop-In: /usr/lib/systemd/system/NetworkManager.service.d
           └─NetworkManager-ovs.conf

Yes.

What is the output of find /etc/systemd  ?

It seems as if I am not the only one with this issue. This thread is pretty new and they have the same issue: https://bbs.archlinux.org/viewtopic.php?id=242228

Re: Disable NetworkManager (starts after every boot)

I note two things.  I don;t think you should have the  dhcpcd service enabled.  the dhcpcd deamon will be stated by netctl as needed (I think)
Also, you have a logind.conf.pacnew file.  you may want to clean that up.

The next step would be to comb the journal for clues, or get out the big hammer and inhibit the NetworkManager service and see what fails.

Thanks for the advice. Will look into it.

grep -r NetworManager /etc/systemd

Nothing.

Re: Disable NetworkManager (starts after every boot)

Please check the journal for the current boot to see if NetworkManager is being activated by dbus-daemon.

Re: Disable NetworkManager (starts after every boot)

Do you have NetworkManager Applet running?  It might trigger NetworkManager to start.
