話說昨天的當機，我查了一下 syslog，有三個訊息頗引我注意的：
1. Window manager warning: last_user_time (**) is greater than comparison timestamp (**). This most likely represents a buggy client sending inaccurate timestamps in messages such as _NET_ACTIVE_WINDOW. Trying to work around...
2. Window manager warning: 0x2400010 (**) appears to be one of the offending windows with a timestamp of 6787489. Working around...
3. Key repeat discarded, Wayland compositor doesn't seem to be processing events fast enough!
我猜第三個訊息（Key repeat discarded）是電腦在和鍵盤說我顧不了你，但第一個與第二個()
