看到我的系统日志，它们充满了这样的消息：
/usr/libexec/gdm-x-session[2564]: (EE) event4 - SIGMACHIP USB Keyboard: client bug: event processing lagging behind by 25ms, your system is too slow
/usr/libexec/gdm-x-session[2564]: (EE) event4 - SIGMACHIP USB Keyboard: client bug: event processing lagging behind by 17ms, your system is too slow
我有一个 12 核系统，当我看到这个时，它基本上处于空闲状态。自从我升级到 Ubuntu 20.10 后似乎发生了这种情况。
我怎样才能找到根本原因以及如何消除这个问题？
