由于某种奇怪的原因，我的 Manjaro 开始表现异常。
首先，它会随机地向我的活动窗口循环发送全屏信号，就像按住 F11 一样。下图显示了正在发生的事情。
我可以通过多次按下外部键盘上的 F11 来停止它，但几分钟后它又会重新启动。间隔没有固定，但可能为 1 到 2 分钟。
其次，触摸板坏了，没有响应，运行时未列出 dmesg，libinput list-devices并且xinput --list。
此外，笔记本电脑键盘上的某些键没有响应，例如 F11 或组合键 lshift + p。但是，当我运行xev命令扫描按下的键时，所有键都会列出，包括 lshift + p。
您可能会说我的硬件出现故障，但如果我使用 SD 卡中的实时 ISO，则一切正常。
我不知道是什么原因造成的，但我猜测与 xorg 有关。
