Well, for the purposes of testing, you can temporarily stop
NetworkManager. This command does that:

$ sudo stop network-manager

(I say "temporarily" because it would come back on a reboot.)

Nope, none of that is needed. Ubuntu and Kubuntu use the same
repository; they differ only in what packages are installed by default.
The GNOME and KDE "versions" [1] of NetworkManager both reside in that
common repository, and they can be installed side-by-side. All you need
to do is:

$ sudo apt-get install network-manager-gnome

Then, if you wanted to run the GNOME "version" instead of the KDE
"version", you would do:

$ killall knetworkmanager
$ nm-applet &

And it should work, even if you are in KDE.

Hope that helps!

Have a good one,
Daniel


[1] Well, strictly speaking, the core of NetworkManger is a daemon that
doesn't care at all about what desktop environment is running. Indeed,
both Ubuntu and Kubuntu use the exact same daemon. However, using the
daemon on its own is rather inconvenient, so various front-ends or
"clients" exist. One is 'nm-applet', which comes in the
network-manager-gnome and is installed by default with Ubuntu; this is
the "GNOME version".  Another is 'knetworkmanager', which is what
Kubuntu installs by default.
