偶发的键盘按键无响应

Kurobac · 2018-08-02 01:47:55

键盘用了两年多，换用Arch之后开始出现，三个月内大概出现过三四次，想不出来是因为什么导致的。
只有键盘上的四个按键（静音，音量加减，启动计算器）无法相应，其余按键全部正常。正常情况下这几个按键是开箱即用的。
按照Wiki排查，dmesg和showkey都无法响应出scancode和keycode。
这次出现之前我在用虚拟机，键盘是Passthrough的，在虚拟机中工作一切正常，中间我还将键盘交还给宿主机调了下音量。虚拟机关闭之后（不知道具体是什么时候）键盘上的四个按键停止响应。
最后重新插拔键盘恢复正常（不在日志里）。

我没看出什么有价值的错误信息……那个Cannot enable. Maybe the USB cable is bad?还是显示器上的USB Hub，我键鼠都是直接插在主板的USB上的……

内核日志不会记录键盘事件啊。所以开虚拟机之前evtest一下键盘设备，从虚拟机交还之后再来一次，看能不能看见scancode和keycode。
不太可能键盘回来了唯独4个键没用了。

不太可能键盘回来了唯独4个键没用了。

按照Wiki的说法，如果kernel没法将scancode转换成keycode，那么内核日志应该是有记录的。
我当时猜想有没有可能是scancode转换为keycode这步出现了问题，但实际上的问题貌似是kernel干脆就没收到scancode。
不过我试了下evtest，发现了一个貌似很有趣的事情：我的键盘有两个对应的event，一个event对应那四个按键，另一个自然就是除了那四个按键之外的所有键。
我手里没有其他键盘，不知道是我这个键盘比较特别还是都这样。
这样的话可能为什么唯独这四个键失效就有一个比较合理的解释了。
不过我对如何复现这个问题还是一头雾水，可能接下来的排查只能等再碰到这个问题的时候了。
顺便贴一下lsusb

看完更迷了，这日志看起来一模一样……

evtest然后按四个键，虚拟机拿走键盘前，拿走后，交还后，都试试看。evtest它是直接从内核-用户态接口read ,ioctl获取事件的，没有什么用户态逻辑，不像showkey要经过Xorg一趟。键盘设备就是按键按下弹起保持之类的事件类，贴一下evtest输出。如果开虚拟机之前正常，不大可能之后内核就彻底收不到四个键的动作了。应该是一直都一样，但是Xorg的某部分逻辑可能被虚拟机进程影响了。

为啥在tty运行的showkey会经过Xorg……
Reset设备之后虚拟机接管键盘，对于用户态的东西来说，这应该和直接把键盘拔掉没什么区别吧？
我切了好几次，evtest输出均相同。虚拟机接管键盘之后/dev/input下面的event直接就没了，没法试。
我看了下输出，没看出什么特别的。
上面的是其余键的event，下面的是那四个键的event，最后是依次按四个键的输出。

你没有看看 journal -n 1000 的输出么？

xtricman · 2018-08-03 10:42:54

那说明按键是正常的，但是Xorg可能有什么地方被虚拟机影响了。

不知道这个虚拟机是靠什么逻辑独占又交还键盘的，估计上游bug。
比较谜，你可以去官方论坛问问

可能我没说清楚。
只是这次出现之前我在用虚拟机，但早在我安装虚拟机之前，这个问题就出现过了。而且我完全想不通什么会触发这个问题。
我的虚拟机用了一个月，每天都在用，切换估计至少切了五六十次，才遇到这个问题……
不过既然叫KVM，那这些切换应该都是在内核中实现的吧……
journalctl

虚拟机大约是23点多关闭的，1点40左右我重新插拔了键盘。
