学生寮の部屋には有線接続がありますが、12.04ではネットワークマネージャーに表示されません。ただし、Windows 7で動作するため、ハードウェアに関連するものではありません。
HDのスペアパーティションに別の12.04をインストールしようとしましたが、それは私の構成が間違っていなかったことを確認するためだけでした。
おもしろいことに、NMは昨日まで接続を認識していたので、これには何らかの更新が必要だと思いましたが、ログにネットワーク関連の何かを壊すことができると思われるものは何もありませんでした。
俺の /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile
dns=dnsmasq
[ifupdown]
managed=false
俺の /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
#iface eth0 inet dhcp
最後の行がコメントされている理由はわかりませんが、コメントを外してみましたが、機能せず、さらに悪いことに「デバイスが管理されていません」と表示されます。その後、managed=true
しかし、接続を認識しないように戻ったため、すべてをロールバックしました。

何か案が?
いくつかのケーブルとスイッチに問題があることがわかりました。だから、Ubuntuのせいではありません!
