所以基本上我会长时间不去管我的电脑。我已将设置设为关闭显示器，我可以通过按下按键或移动鼠标来唤醒机器。但今天似乎 Xorg 崩溃了 - 我无法唤醒机器。
首先，我使用的是 Arch Linux，所有软件包都已更新，没有测试软件包。我的设置只有 KDE + Xorg。
当我检查我的日志（journalctl -xe）时，我看到大约 300 次出现（全部具有相同的时间戳，这有点令人担忧）：
Mar 13 20:03:04 Ethan-PC baloo_file_extractor[2164]: org.kde.baloo.engine: PostingDB::put MDB_BAD_TXN: Transaction must abort, has a child, or is invalid
Mar 13 20:03:04 Ethan-PC baloo_file_extractor[2164]: org.kde.baloo.engine: PositionDB::put MDB_BAD_TXN: Transaction must abort, has a child, or is invalid
然后我得到这个：
