• 请问‘卡死’出现的时候，能够切换tty吗，ctrl+alt+F2
• 能够使用快捷键alt+tab切换窗口吗
• 具体是操作了什么导致了这个现象的出现呢？可以在重启后，获取日志，sudo dmesg > dm.log发送至[email protected]哈

我也多次出现系统卡死的情况，只有鼠标能动，其他任何键盘操作都无响应，系统资源肯定不满，猜测是某个APP卡死引起的。

我也发现这个问题了，需要每次ctrl+alt+F2切换到tty ，然后systemctl restart lightdm.service。重启一次桌面环境才能正常。在我的机器上，机器持续运行一般两天左右就会出现一次。感觉是桌面环境哪里有bug
