机型： dell xps13 开发者版本（自带ubuntu 14.04)
我是学生，之前一直用的mac，但是要学linux系统编程就买了这个电脑作为学习用，所以对ubuntu非常不熟悉。今天系统自带的软件中心发了一个更新推送，我更新了之后重启发现网卡和声卡都失效了。用ifconfig查看只能看到lo。
求大神帮忙解决一下。
重启之前系统又问是否禁止uefi, 我没有选，之后我进bios看，boot选项里是uefi的选项是勾上的。
谢谢

先處理網卡問題

0. uname -a
1. sudo lspci -knn
2. sudo lshw -numeric -class network
3. sudo ifconfig -a
4. sudo parted -l print
把結果全部直接 選取/複製/貼上來
