如何在 Zenbook 中查找失去的韌體？

這個答案促使我在我的超極本中找到失去的韌體，因為我在使用 Dvorak 的一天舊 Debian 8.5 中遇到了許多工件（這裡是關於無法校準打字速度）和 CPU 上下波動的困難。Stephen 說，無論何時安裝或升級核心包，它們都可以告訴您缺少的韌體。但是，我想獲得更完整的評論。特徵

• 關於失敗的韌體，iwlwifi舊消息在哪裡，我想

在 debian 中安裝的韌體和刪除的軟體包

• apt-get -t jessie-backports install linux-image-amd64
• apt-get -t jessie-backports install firmware-iwlwifi
• apt-get remove xserver-xorg-video-intel

斯蒂芬回答後的第二次迭代

該軟體包解決了此處non-free描述的 Matlab 2016a 中的圖形工件。我的 dmesg 現在一切正常

$$ Stephen $$因為wifi韌體17-21次失敗，16次迭代最終成功；沒有其他可見的韌體故障

硬體：華碩 Zenbook UX303UA

作業系統：Debian 8.5 64 位

Linux 核心：4.6

要找出您的系統正在尋找但找不到的韌體（這是您可能需要的韌體），您應該在核心日誌中查找與韌體相關的消息：

dmesg | grep firmware

這將為您提供核心正在尋找的韌體文件的名稱；apt-file然後會告訴您要安裝哪個軟體包（如果韌體已打包）。

你有一個執行 Intel GPU 的 Skylake 系統，你可能至少需要firmware-misc-nonfree（Skylake GPU 需要韌體）：

apt-get -t jessie-backports install firmware-misc-nonfree

這將修復i915韌體載入錯誤。消息序列以iwlwifi結尾loaded firmware version 16.242414.0 op_mode iwlmvm，所以沒關係；同樣，藍牙韌體也已成功載入（它也包含在firmware-iwlwifi包中）。
