我試圖理解為什麼當我關閉顯示器並重新打開它時我的 Ubuntu 會被登出。我進入隱私設定並關閉螢幕鎖定，它仍然發生。我在電源設定中關閉了自動掛起和黑屏。我甚至使用咖啡因來防止任何事情讓我退出。當我關閉電視並重新打開時，這種情況仍然發生。然而，當我使用遙控器更改輸入並將其切換回 Ubuntu 時，我仍保持登入狀態。
我在一台新建置的 PC 上執行 Ubuntu 17.10。它是 i5-8400 咖啡湖，4GB RAM，asrock 370m MB，僅運行集成 GPU，因為它僅用於視頻（htpc）並且希望消耗盡可能少的電量。
這是日誌，也許有什麼原因導致崩潰（如在 ubuntu 論壇上其他地方閱讀的那樣）。

我在 11 點左右離開了我的 HTPC，並在下午 2 點左右回來。我在 14:05 左右再次重現了同樣的問題。
我在那裡看到了一些錯誤，但我仍然需要幫助找出主要問題是什麼。
我認為當我重新打開螢幕時會發生一些事情，因為當我將其打開進行視訊編碼時，工作最終會完成......只有當我重新打開螢幕時它才會停止工作。我在網上搜尋並詢問了不同的人，但沒有人能夠找到解決方案。
非常感謝您的幫助，因為我非常想解決這個問題！先致謝
