今天略微合拢了一下笔记本,然后Ubuntu unity死掉了,Ctrl-Alt-1进入terminal, 登录后重新启动系统,发现wif不能用了。
上网查了一个命令,可以检查软硬件禁用的状况:
[email protected]:~# rfkill list 1: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 2: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: yes 3: dell-bluetooth: Bluetooth Soft blocked: no Hard blocked: yes
由于是硬件禁用,用
rfkill unblock all
命令是解决不了的。
好在笔记本上有键盘快捷键 Ctrl-F2,按下后解决了。
[email protected]:~# rfkill list 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no 2: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: no 3: dell-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 4: hci0: Bluetooth Soft blocked: no
再看一下rfkill命令介绍。
rfkill - tool for enabling and disabling wireless devices
这个工具还是不错的。
Ubuntu wifi 启用
