To confirm this, in GNOME from Computer – Yast – Network Devices – Network Settings, check for option “User Controlled with Network Manager” under Network Setup Method. Or, check for the line ‘NETWORKMANAGER=”yes”‘ in /etc/sysconfig/network/config file. This may not be a viable option to use on SUSE enterprise Desktop as in a enterprise environment you wouldn’t want the user to modify or control network settings.Read More →
