為什麼 X 不以與 Mod1 不同的方式對待 ALT_L 和 ALT_R

Mod1我已將via的定義更改xmodmap為不包含ALT_R（以了解為什麼要滾動到底部）。修改器的目前佈局如下。儘管ALT_R不參與 的定義mod1，但由 產生的記錄xev顯示，當按下任一 Alt 鍵時，KeyEvent.state被設定為mod1Mask（在 中定義為 8 ）。/usr/include/X11/X.h

如果xmodmask說不是ALT_R，mod1為什麼X報告ALT_R+f好像是？

xmodmap:  up to 4 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock        Caps_Lock (0x42)
control     Control_L (0x25),  Control_R (0x69)
mod1        Alt_L (0x40),  Meta_L (0xcd)
mod2        Num_Lock (0x4d)
mod3      
mod4        Super_L (0x85),  Super_R (0x86),  Super_L (0xce),  Hyper_L (0xcf)
mod5        ISO_Level3_Shift (0x5c),  Mode_switch (0xcb)

以下序列是ALT_L+f後接ALT_R+ f。

背景:

ALT_R我有一個使用+ENTER來執行功能的應用程式。在 Xmonad 中使用此應用程式時，組合Mod1+ENTER會觸發「將目前視窗與主視窗交換」功能。預設情況下，ALT_L和ALT_R映射到Mod1.

在我的 中.xinitrc，在啟動 Xmonad 之前，我已經更改了我的鍵映射，xmodmap這ALT_R不是Mod1定義的一部分。儘管如此，Xmonad 在輸入ALT_R+時仍然執行視窗交換行為ENTER。 Xmonad 似乎不知道Mod1不再包含ALT_R.

這是我的.xinitrc

# Java's GUI can't handle some non-reparenting window managers like
# Xmonad without being told how to behave
export _JAVA_AWT_WM_NONREPARENTING=1

# The right Alt key is useful in IntelliJ, tell Xmonad to ignore it
xmodmap ~/.Xmodmap

# Start Xmonad
xmonad

xmodmap這是上面 Xmonad 啟動後的輸出。

我已經記錄了該序列xev並確認該ENTER序列從未註冊過。相反，在記錄後會發生多個FocusIn/FocusOut事件。ALT_R

答案1

似乎如果 Alt_R 未分配給任何其他修飾符，則它預設為 Mod1Mask。

簡單地取消綁定Xmodmap 中的正確alt 不足以讓它停止報告狀態0x8，我必須將其綁定到另一個修飾符（我選擇Mod3，因為它無論如何都是空的），然後xev 開始報告狀態0x20。

儘管它更多的是一種解決方法而不是解決方案。
