我已经查看了有关如何下载 debian 源包、构建它们，然后安装生成的 deb 文件的说明，但我觉得缺少的是如何逆转它并返回使用从 debian 存储库中获取的官方（二进制）包的说明。
我正在运行 xfce，据我所知，暂停键未映射为热键。当按下暂停键时，它只会产生：
FocusOut event, serial 37, synthetic NO, window 0x3000001,
mode NotifyGrab, detail NotifyAncestor
FocusOut event, serial 37, synthetic NO, window 0x3000001,
mode NotifyUngrab, detail NotifyPointer
FocusIn event, serial 37, synthetic NO, window 0x3000001,
mode NotifyUngrab, detail NotifyAncestor
KeymapNotify event, serial 37, synthetic NO, window 0x0,
keys: 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
如果我将暂停键重新映射到完全不同的东西也没关系，例如：
key <PAUS> {
// type= "PC_CONTROL_LEVEL2",
symbols[Group1]= [ p, Break ]
};
如果我按 Shift+Pause 我会得到响应：
KeyPress event, serial 37, synthetic NO, window 0x3000001,
root 0x1ef, subw 0x0, time 679325549, (37,115), root:(1228,774),

为什么未移位的暂停键达不到 xev？
