螢幕鎖定後顯示崩潰

March 11, 2022

我在聯想 Ideapad 上使用的是 Ubuntu 20.04 版本

每當我鎖定我的筆記型電腦（或者它被鎖定在不活動狀態）並嘗試解鎖時，我的顯示器就會崩潰。我看到如下螢幕

我有另一台外接顯示器連接到這台筆記型電腦，顯示器看起來不錯。

這種情況僅在幾天后才開始發生。我還嘗試查看是否有任何最近的更新導致了這種情況。但我看不到任何相關的東西。這是日誌。

我有一個雙啟動。所以在 Windows 上嘗試了同樣的方法，即使在鎖定螢幕後它也能正常工作。我不知道 Ubuntu 中是否有任何影片驅動程序受到干擾。任何幫助請！

我有一個同樣問題的聯想筆記型電腦（AMD 架構）。問題在於核心 5.13 的最新更新。
通過鍵入此命令檢查您的核心版本
uname -r
如果您有 5.13 或更高版本，您可以通過降級到較低版本（例如 5.11）來解決此問題。
這不是最終解決方案，但它可以幫助您，直到新更新檔發布。
有一些教程可能有用：
安裝和引導舊核心
刪除舊的（未使用的）核心

正如Du Dy在他的回答中所建議的，我檢查了核心版本，它確實是 5.13。
然後，我通過執行以下操作檢查了在 5.13 安裝之前還有哪些其他版本：
dpkg --list | grep linux-image
選擇了一個舊版本 5.11.0-44 並再次安裝
sudo apt install linux-image-5.11.0-44-generic
並啟動到這個 5.11 核心。它解決了顯示問題，但很多事情都不起作用。比如網路、外接顯示器等…
嘗試通過執行 a 來比較其他已安裝核心的所有安裝，dpkg --list | grep linux-並發現 5.11 缺少 modules-extra 包
引導回新核心（工作但顯示問題的核心）並安裝失去的軟體包
sudo apt install linux-modules-extra-5.11.0-44-generic
啟動到 5.11，一切正常
