几天前，我的系统（Ubuntu 22.04.3 LTS 64 位）运行正常。突然之间（我不记得做了什么与平常不同的事情），我的笔记本电脑开始在合上盖子时不进入睡眠状态。屏幕变黑但仍亮着，风扇继续转动，鼠标仍然发光，这在睡眠模式下不应该发生，所以计算机实际上并没有挂起。问题是我无法将 PC 从这种状态唤醒，我所做的任何事情似乎都不会对它产生任何影响，我必须按住电源按钮强制关机。我尝试从关机菜单使其进入睡眠状态，但仍然得到相同的结果。每次我的 PC 进入“睡眠”状态时（我不认为它真的要睡觉了，因为我能听到风扇的声音，看到鼠标发光），我除了强制关机外没有其他办法唤醒它。
我也尝试将其关闭并重新启动，得到了类似的结果：关闭屏幕弹出，上面有我的电脑的徽标和加载轮，但加载轮消失后，徽标就留在那里，电脑并没有真正关闭，所以我必须再次按下电源按钮强制关闭。
我尝试在 Google 上搜索答案，但找不到太多答案，而且我真的不知道从哪里开始诊断问题。有人知道可能发生了什么吗？
编辑：
运行该journalctl --grep='sleep|suspend|resume' --no-pager --since='-1hour'命令给了我这个输出：
