最近，我的 22.04 安裝開始以一種特殊的方式凍結：
- 螢幕凍結；
- 鍵盤輸入看似沒有做任何事；
- 但電腦仍在工作。
我知道3這是真的，因為我在 Zoom 通話凍結時一直在通話；通話繼續進行，我可以聽到人們說話，但是，正如我所說，螢幕被凍結，我對鍵盤（例如 ++ ）所做的任何操作Ctrl都Alt不起作用F1。
我升級到23.04，但問題仍然存在。
我在凍結之前檢查了系統日誌，但無法從這些日誌中找出發生了什麼。
問題解答：
- 我沒有更改預設圖形驅動程式。
- 我的核心是6.2.xxx。
更新：
我認為這與火狐瀏覽器有關。我已經插入了一個新的在下面記錄它發生的位置（並且由於字數原因刪除了舊的）立即地打開火狐瀏覽器後。

答案1
不幸的是，日誌沒有給出任何關於問題根源的明確指示。
此問題通常可能是由不穩定的顯示卡驅動程式引起的。弄亂圖形驅動程式可能會損壞您的作業系統（因此請先備份！），但您可以嘗試前往 Ubuntu 中的「其他驅動程式」應用程式並嘗試備用驅動程式。如果這些不起作用，您也可以直接從製造商安裝驅動程式（如果他們提供）。
這個問題也可能是由記憶體（RAM）不良引起的，但如果發生這種情況，我不希望縮放等繼續工作。您可以使用 memtest86+ 等工具來測試這一點。
