Ubuntu 20.04 隨機凍結，有時在 20 分鐘後，有時在幾個小時後。
這意味著我無法移動滑鼠，也無法使用鍵盤執行任何操作。如果正在播放聲音，則會在約 2 秒的時間內循環播放。鍵盤組合沒有任何作用。只有使用電腦電源開關進行硬重啟才能重新啟動我的電腦。
根據這個帖子我收集了一些信息，儘管我是這些事情的新手，並且無法真正理解其中的任何內容：

如果與此無關，我很抱歉。我懷疑我的 GPU 無法正常工作，因為我的程式運行速度比同一系統上的雙啟動 Windows 慢得多。另外，在執行一些程式時，我遇到了一些 libcudart 和 libcublas 錯誤，據我所知，這些錯誤似乎與我的 GPU 有關。
您對如何排查或解決此問題有什麼建議嗎？
根據要求，我運行了命令dmesg、cat /var/log/syslog，journalctl結果如下：
由於正文限制，我無法將所有程式碼貼到此處，因此我將其放在 GitHub 上。

我將給出可能的解決方案：
- 重新安裝 Gnome：
sudo apt-get update
sudo apt-get install --reinstall systemd gnome-settings-daemon gnome-settings-daemon-common
我來更新一下...
