下面说一下网络连接的问题吧，为了使像Ubuntu一样在任务栏里面出现网络连接的图标，需要安装NM的支持，即:
apt-get install network-manager。
不过此时虽然出现了连接图标，但选项是和灰色的，仍然会看到网络设备未托管的提示，这是由于Linux里面的两套网络管理方案出现冲突造成的：文档点此 解决方案为：
将/etc/NetWorkManager/nm-system-settings.conf 中的managed=false改为=true然后重启：
/etc/init.d/networking restart 即可。
不过细心的话大家仍然可以发现依旧有问题残留，那就是在网络的下拉列表中并不是出现Ubuntu中我们所熟悉的Auto eth0，而是许多ifupdown的永久有线连接，并且无法对其进行编辑，这时的解决方案如下：
修改/etc/dbus-1/system.d/NetworkManager.conf 和/etc/dbus-1/system.d/nm-applet.conf，将其中显示为：
<policy context=default>
<deny own=”org.freedesktop.NetworkManager”/>
<deny send_destination=”org.freedesktop.NetworkManager”/>
<deny send_interface=”org.freedesktop.NetworkManager”/>
</policy>
中的deny改为allow，然后重启dbus：
/etc/init.d/dbus restart
停止NetWorkManager:
/etc/init.d/network-manager stop
删除interfaces：
rm /etc/network/interfaces
重启NetWorkManager：
/etc/init.d/network-manager start
即可。
