Re: nm-connection-editor not working

[Neal Becker <ndbecker2 gmail com>]

Interesting.

I was using x2go remote desktop.

I rebooted but no difference.

Then I hooked up monitor and kb, and logged in locally.  With local connection, nm seems to work normally.

While logged in locally, I tried x2go and nm worked remotely.

Then logged off local, logged off remote.

Then start x2go again.  Once again, nm doesn't work through remote connection.

Ok, that shows that it's a D-Bus issue, not an NM specific one AFAICT.
Have you recently updated either NetworkManager or D-Bus?

First thing to try is "sudo killall -HUP dbus-daemon" to get it to
reload permissions.

Next thing to try is a reboot; there may still be one or two cases where
D-Bus doesn't correctly reload permissions after clients (like
NetworkManager) are updated; I just saw a bug fix for something like
that this week.

Last idea may be SELinux?  Try "setenforce 0" if you're running in
Enforcing mode, but I don't think SELinux is a likely culprit here.
