Solve the practical problem of the Ubuntu control panel network-manager icon

My Ubuntu Network icon is displayed as "wireless network" instead of "two computers ". In addition, there are only several virtual machine Nic configurations in the "Edit connection" "Wired" column, without eth0. Ifconfig can display eth0, and the machine can access the Internet normally. In Linux, there are two sets of network connection management solutions:/etc/Network/interfaces (/etc/init. d/networking) and network-Manager. The two solutions are in conflict and cannot

My Ubuntu Network icon is displayed as "wireless network" instead of "two computers ". In addition, there are only several virtual machine Nic configurations in the "Edit connection" "Wired" column, without eth0. Ifconfig can display eth0, and the machine can access the Internet normally.

In Linux, there are two sets of network connection management solutions:/etc/Network/interfaces (/etc/init. d/networking) and network-Manager.
The two solutions conflict and cannot coexist at the same time.
The first solution is applicable to environments without X, such as servers or those that do not need to change the connection at all.
The second solution is to use a desktop environment, especially a notebook, to change the network connection conditions at any time.

To avoid conflicts and share configurations, the two of them have the following solutions:
When Network-Manager finds that/etc/network/interfaces has been changed, it closes itself (shown as unhosted) unless the management settings come true.
When managed is set to true,/etc/network/interfaces does not take effect.

Therefore, edit the/etc/NetworkManager/nm-system-settings.conf file:
Vi/etc/NetworkManager/nm-system-settings.conf
Find the following line:
Managed = false
And modify it:
Managed = true
After restarting, the "two computers" Network icon is displayed correctly, and the "connection information" is displayed normally.
