我的Ubuntu 是使用14.04 LTS版本,之前為了解決WIFI不能用的情況有更新過內核
vodka@vodka-ThinkPad-T580:~$ uname -sr
Linux 4.6.4-040604-lowlatency

然後安裝了iwlwifi-8265-ucode-22.361476.0.tgz驅動包,現在WFI已經正常運作。
接下來還剩下bluetooth的問題,在我的「系統設定值」.「藍牙」裡面看到顯示藍牙以停用。

在網路上找了一些文章,查看了rfkill list 這個指令
vodka@vodka-ThinkPad-T580:~$ sudo rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
不過只要重新開機就會恢復成
vodka@vodka-ThinkPad-T580:~$ rfkill list
0: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
不知道怎樣把他固定住?

也有人說要按Fn+藍牙按鍵(我的是F10),可是都沒什麼反應。

請問這個問題有什麼解決方式嗎?
如果需要提供什麼訊息,也請留言告訴我,我會盡快貼上來。

先謝過大家的幫忙!

我對您提到的議題,以前沒去探索過,所以並不清楚怎麼解決您遇到的問題,

剛剛根據您提供的關鍵字,做了點探索,以下只是簡單紀錄目前探索到的,

不見得能解決您的問題,不過可以提供您參考,也許能引發您新的靈感,找到一個探索的起點。

================================================================================

執行「$ man rfkill」,來閱讀相關的說明。

我的環境是「Ubuntu 18.04」,在我的環境執行


$ rfkill --version



或是執行


$ rfkill -V



顯示


rfkill from util-linux 2.31.1



================================================================================

執行


$ rfkill --help



或是執行


$ rfkill -h



或是執行


$ rfkill help



顯示


Usage:
 rfkill [options] command [identifier ...]

Tool for enabling and disabling wireless devices.

Options:
 -J, --json             use JSON output format
 -n, --noheadings       don't print headings
 -o, --output <list>    define which output columns to use
 -r, --raw              use the raw output format

 -h, --help             display this help
 -V, --version          display version

Available output columns:
 DEVICE      kernel device name
 ID          device identifier value
 TYPE        device type name that can be used as identifier
 TYPE-DESC   device type description
 SOFT        status of software block
 HARD        status of hardware block

Commands:
 help
 event
 list   [identifier]
 block   identifier
 unblock identifier

For more details see rfkill(8).



================================================================================

執行


$ rfkill



顯示


ID TYPE DEVICE      SOFT      HARD
 0 wlan phy0   unblocked unblocked



執行


$ rfkill -o ID



顯示


ID
 0



執行


$ rfkill -o TYPE



顯示


TYPE

================================================================================

執行


$ rfkill list



顯示


0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no




================================================================================

執行


rfkill block 0



上面指令執行完畢後,接著執行下面指令


$ rfkill list



顯示


0: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no



================================================================================

執行


rfkill unblock 0



上面指令執行完畢後,接著執行下面指令


$ rfkill list



顯示


0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no



================================================================================

套用上面的模式,一些可以執行的範例


$ rfkill block all
$ rfkill list
$ rfkill unblock all
$ rfkill list





$ rfkill block wlan
$ rfkill list
$ rfkill unblock wlan
$ rfkill list



更多的「TYPE」,可以參考「man rfkill」裡「EXAMPLES」的最後一個範例。

================================================================================

先開啟一個「Terminal - 1」,執行下面指令


$ rfkill event



顯示


2018-07-29 10:11:55,367271+0800: idx 0 type 1 op 0 soft 0 hard 0



再開啟一個「Terminal - 2」,執行下面指令


$ rfkill block all



在剛剛「Terminal - 1」,就會有新的事件顯示,顯示如下


2018-07-29 10:11:55,367271+0800: idx 0 type 1 op 0 soft 0 hard 0
2018-07-29 10:12:09,128180+0800: idx 0 type 1 op 2 soft 1 hard 0



在「Terminal - 2」,執行下面指令


$ rfkill unblock all

================================================================================

從「man rfkill」那,

在「SEE ALSO」,看到一個關鍵字「systemd-rfkill(8)」

所以可以執行「man systemd-rfkill」來閱讀相關的說明。

================================================================================

執行


$ dpkg -S systemd-rfkill | sort



顯示


systemd: /lib/systemd/systemd-rfkill
systemd: /lib/systemd/system/systemd-rfkill.service
systemd: /lib/systemd/system/systemd-rfkill.socket

systemd: /usr/share/man/man8/systemd-rfkill.service.8.gz
systemd: /usr/share/man/man8/systemd-rfkill.socket.8.gz



執行


$ dpkg -S systemd-rfkill | grep man | sort



顯示

systemd: /usr/share/man/man8/systemd-rfkill.service.8.gz

* $ man systemd-rfkill
* $ man systemd-rfkill.service
* $ man systemd-rfkill.socket


================================================================================

或是從另一個方向來探索起


$ whereis systemd-rfkill



顯示


systemd-rfkill: /usr/share/man/man8/systemd-rfkill.8.gz



執行


$ dpkg -S /usr/share/man/man8/systemd-rfkill.8.gz



顯示


systemd: /usr/share/man/man8/systemd-rfkill.8.gz



表示「/usr/share/man/man8/systemd-rfkill.8.gz」來自於「systemd」這個套件。

執行


$ dpkg -L systemd | grep rfkill



顯示


/lib/systemd/systemd-rfkill
