正如我所提到的这里由于某种原因,每当我尝试使用CTRL任何键盘快捷键时,它都会打印插入符号^

我需要诊断为什么会发生这种情况以及如何解决它。
答案1
我会看看以下内容:
xmodmap -pke
就像在我的系统上一样,控制键是:
这将列出您的键的当前映射。如果您发现有问题的设置,您可以重新分配该键。
keycode 37 = Control_L NoSymbol Control_L keycode 105 = Control_R NoSymbol Control_R
使用 xev 找出密钥流是什么,然后将其重新映射回控制。
我的 xev 显示此控制:
KeyRelease event, serial 37, synthetic NO, window 0x3000001, root 0x15c, subw 0x0, time 5417642, (167,-18), root:(195,67), state 0x14, keycode 37 (keysym 0xffe3, Control_L), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False
就像是:
xmodmap -e "keycode 37 = Control_R NoSymbol Control_R"
将使我的控制键正常工作。
要使其永久化,请编辑您的 xorg 配置文件以反映新的映射。
