無法在 13.10 中啟用藍牙

無法在 13.10 中啟用藍牙

我在這個問題上經歷了一段非常艱難的時光...

我從去年開始就擁有我的 ASUS X301A,僅在 Ubuntu 12.04 下使用,直到最近(一個月左右),我切換到了 13.04。最近,我買了一款藍牙耳機,它就像我的手機的魅力一樣,提醒我我的電腦上有藍牙。

現在進入正題:我似乎不知道如何讓藍牙工作。當我嘗試透過 GUI 啟用它時,它不起作用任何事情

編輯:我升級到 13.10 並重新運行檢查,這是我現在得到的:

現在更好的是,藍牙根本不會出現rfkill

答案1

你好,我的時間很短,因為我在工作。我可以給你一個提示,也許是一個假設的解決方案;)。兩週前我的 BT 轉接器(USB)也出現了問題。我的是:

Bus 004 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

但我的症狀與您在 14.04 LTS 上描述的症狀完全相同。經過長時間的研究,我發現藍牙驅動程式在幾個月前變得有點問題。它與驅動程式嘗試初始化 BT 設備時設定的模式有關。據我所知,這是一個錯誤修復,結果在某些設備上不能很好地工作。

BT 核心驅動程式變得不穩定。還有一個補丁的鏈接,使我的 BT 加密狗再次工作:修復不穩定的BT驅動補丁

我沒有將補丁應用到我的內核,因為我暫時時間不夠,而且BT 對我來說並不是那麼重要,但由於補丁已應用到下一個14.04 LTS 的Ubuntu 內核,所以我安裝了這個內核,並且BT再次完美運行。由於我有 NVidia 顯示卡,我無法使用此內核,因為 nvidia 304-updates 軟體包不適用於此版本,但在命令列上一切正常。

如果您可以切換到 14.04 LTS 並等待下一個核心版本或下載核心原始碼包,請套用補丁並編譯您自己的核心。

希望對你有幫助,祝你好運
