Xmodmap 无法重新映射修饰键

当我尝试移动按键，以便在退出键上有 CapsLock，在 CapsLock 上有 Control，在左控制键上有 Escape 时，我收到以下错误：

% xmodmap ~/.Xmodmap
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  118 (X_SetModifierMapping)
  Value in failed request:  0x17
  Serial number of failed request:  15
  Current serial number in output stream:  15

这是失败的代码：

remove Lock = Caps_Lock

! ESC
keycode 9 = Caps_Lock
add Lock = Caps_Lock
remove Control = Control_L

! CapsLock
keycode 66 = Control_L
add control = Control_L

! Control_R
keycode 37 = Escape

! 2*Meta_L
keycode 148 = Meta_L
add mod1 = Meta_L

如果我注释掉以add或开头的所有行，remove它会正常运行，但不会执行我想要的操作。

程序版本（Gentoo x86（稳定））：

  • xorg-服务器-1.7.6
  • xmodmap-1.0.4
  • xf86-输入-evdev-2.3.2

更新之前一切正常。

答案1

大多数情况下，当我收到此错误时，是因为我尝试将一个键符号分配给修饰符，但该键符号已用于其他修饰符。尝试运行“xmodmap -pm”并验证您尝试分配给修饰符的键符号尚未被使用。

例如，如果 Meta_L 已分配给 mod4，那么如果您尝试将 Meta_L 分配给 mod1 而不先将其从 mod4 中删除，则可能会出现此错误。

答案2

根据Xmodmap 手册，您似乎遗漏了至少一个关键步骤。您不仅必须“删除”修饰键位分配，还必须“清除”修饰键组中的键。

是的，我知道这确实令人困惑！

这些任务/命令似乎也必须按照特定的顺序运行：

  1. 删除/清除组和键的分配
  2. 将键盘符号分配给所需的键码
  3. 将键盘符号添加到适当的修饰符组

我看到这个帖子已经有一段时间没有活动了，显然已经死了（原作者已经解决或放弃了这个问题）。但希望这个澄清可以帮助其他遇到类似情况的人。
