The KDE NetworkManager plasmoid used in openSUSE 11.4 has some issues and rough edges. Some of those will be
fixed in an online update expected to be out soon. If you want to help make the NetworkManager plasmoid better you
can read about filing good bug reports against it here.
If the plasmoid is not working for your needs you can easily and safely use the GNOME NetwokManager applet (nm-applet)
in KDE instead. Just follow the steps below (# means run as root, $ means run as normal user):
1) Upgrade oxygen-gtk – otherwise nm-applet will fail to start:
# zypper addrepo -f http://download.opensuse.org/repositories/KDE:/UpdatedApps/openSUSE_11.4 kua
# zypper install 'oxygen-gtk>=1.0.3'
2) Install nm-applet:
# zypper install NetworkManager-gnome
3) Remove the KDE applet:
# zypper remove NetworkManager-kde4-libs
4) Make nm-applet autostart on login:
$ ln -s /usr/bin/nm-applet ~/.kde4/Autostart/nm-applet-link
5) Reboot
Thanks to oxygen-gtk nm-applet will even integrate quite well in the look and feel of KDE.v
EDIT: An updated version of the KDE NetworkManager plasmoid is now available in the KDE:UpdatedApps
repository. You may want to try this before moving to the GNOME applet. Install it as follows:
Add the repository:
zypper addrepo -f http://download.opensuse.org/repositories/KDE:/UpdatedApps/openSUSE_11.4/ kua
Upgrade the packages:
zypper in 'plasmoid-networkmanagement>=0.9.1git20110503' 'NetworkManager-kde4-libs>=0.9.1git20110503'
You will be asked to allow vendor change for some packages. And you might be asked to remove NetworkManager-kde4. Allow both.v
