自动重复不起作用

在我的笔记本电脑上，打开自动重复 ( xset r on) 不起作用。在检查 的输出时xev，似乎自动重复失败的原因是因为间歇性地按下了另一个键（尽管我没有按下任何键），这取消了自动重复当前按住的键。当没有按下任何键时，将持续重复记录以下事件：

KeyPress event, serial 33, synthetic NO, window 0x1200001,
    root 0x123, subw 0x0, time 1652400, (-509,794), root:(455,814),
    state 0x0, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 33, synthetic NO, window 0x1200001,
    root 0x123, subw 0x0, time 1652400, (-509,794), root:(455,814),
    state 0x0, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

似乎正在按下键码为 221 的键，即使实际上并未按下。

因此，是否可以完全禁用某个键码，使 xorg 根本接收不到来自该键码的按键信号？或者，是否可以使按键在按住时自动重复，无论是否按下另一个键？

更新：

运行后sudo evtest，似乎当隐藏输出来自

/dev/input/event11 PEAQ WMI hotkeys

当没有按下任何东西时，似乎没有其他输入设备会发送事件。在 evtest 中检查键盘事件时，自动重复起作用。

xev当没有按下任何按钮时运行几秒钟的完整输出：

答案1

看来这是内核 4.13 引入的一个错误，根据Redhat bugzilla 错误 #1497861。

我发现卸载peaq_wmi模块也是一种解决方法；似乎有人已经提交了补丁来解决这个问题。

（要卸载peaq_wmi模块，可以发出命令sudo modprobe -r peaq_wmi。）

答案2

事实证明，禁用 PEAQ WMI 热键可以修复该问题。我通过首先检查禁用 PEAQ WMI 热键xinput list来查找 id：

[email protected]:~$ xinput list
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Dell Dell KM632 Wireless Keyboard and Mouse   id=11   [slave  pointer  (2)]
⎜   ↳ Dell Dell KM632 Wireless Keyboard and Mouse   id=12   [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                id=16   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Video Bus                                 id=8    [slave  keyboard (3)]
    ↳ Sleep Button                              id=9    [slave  keyboard (3)]
    ↳ Dell Dell KM632 Wireless Keyboard and Mouse   id=10   [slave  keyboard (3)]
    ↳ Lenovo EasyCamera: Lenovo EasyC           id=13   [slave  keyboard (3)]
    ↳ Ideapad extra buttons                     id=14   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=15   [slave  keyboard (3)]
    ↳ Dell Dell KM632 Wireless Keyboard and Mouse   id=18   [slave  keyboard (3)]
    ↳ PEAQ WMI hotkeys                          id=17   [slave  keyboard (3)]

在本例中，id 是 17。然后，在 .xinitrc 中，我添加了xinput --disable 17, 或引起问题的 id，这解决了问题。

答案3

最新内核更新后，我在elementaryOS 上遇到了同样的问题。我发布了有关它的信息这里。使用答案之一，sudo modprobe -r peaq_wmi为我解决了这个问题。

编辑：添加xinput --disable 17到 .xinit 中不是为我永久解决这个问题，所以我在每次启动后运行上面的命令。我的 Lenovo Yoga 500-14IHW 运行在elementaryOS 上。

另外，这个bug与Arch linux无关，所以请标记它，以便更多的人找到这个问题的解决方案。
