A variety of bugs network Manager

Network Manager is a network management software under the Gnome desktop system that links computers to the Internet. In most cases, network manager is very useful. Right-click Panel,edit connections and then set it up. However, after a period of use, I found a number of bugs, here to write and study together.

First of all, tell me about my configuration. My Computer is Dell Vostro 1320,coreduo t6700,2g memory, Nvidia 9300GS graphics card.

The first bug I encountered was related to the graphics driver I installed. My driver was downloaded on the Nvidia official web site. Run program, exit x server after installation, everything is OK. However, the Network Manager Control Panel displays "Device not managed" after a reboot. After surfing the web for Google, the answer is this:

Edit the/etc/networkmanager/nm-system-settings.conf file with a text editor, which is sudo gedit/etc/networkmanager/ nm-system-settings.conf, then change the [Ifupdown]managed=false] inside to true, and then reconfigure the link.

The second more important bug is that network link PPPoE is always problematic. I use pppoeconf instead of network Manager, more stable.

In the terminal play Sudo pppoeconf, set is a yes, and then into the user name and password can be online. At this point network manager still shows no connection, but has not affected the Internet.

There's a lot of trouble with the software.
