我運行的是 Ubuntu 22.04，但出現了凍結現象，而 Windows 上不會發生這種情況。滑鼠停止移動，電腦完全沒有反應。 ALT + Print Screen + REISUB 也不行。
我還遇到了一個問題，僅在 Ubuntu 中 - 顯示器閃爍。解決這個問題的唯一方法是關閉 Nvidia 驅動程式中的抖動功能，但這會降低影像質量，不符合我的口味。
最重要的是我認為我的 Nvidia 驅動程式有問題。當我用筆記型電腦寫這篇文章時，我重新啟動了電腦，輸入密碼後它再次凍結。
我可以看到任何錯誤日誌來開始診斷嗎？
這是上次崩潰的系統日誌：

答案1
我注意到，只有當我讓電腦閒置時，電腦才會凍結——沒有播放音樂，也沒有移動滑鼠。我用谷歌搜尋“ubuntu 在空閒時凍結”並發現了這個：
核心中存在一個錯誤，導致 ryzen cpu 在進入某個 c 狀態（電源模式）時凍結。通常這種情況發生在電腦空閒了一段時間並且核心嘗試將CPU置於低功耗模式時，只有重置才能再次喚醒CPU。
我從 BIOS 中禁用了 C-State，到目前為止還沒有出現任何凍結情況。我安裝了最新的Ubuntu版本，為什麼這個bug仍然存在我不知道。
