ubuntu 14.04 设置caps为ctrl

键位设置规则在下列文件中

$ grep -e "ctrl:\|:ctrl" /usr/share/X11/xkb/rules/evdev.lst grp:ctrls_toggle     Both Ctrl keys togethergrp:ctrl_shift_toggle Ctrl+Shiftgrp:ctrl_alt_toggle  Alt+Ctrlctrl:nocaps          Caps Lock as Ctrlctrl:lctrl_meta      Left Ctrl as Metactrl:swapcaps        Swap Ctrl and Caps Lockctrl:ac_ctrl         At left of 'A'ctrl:aa_ctrl         At bottom leftctrl:rctrl_ralt      Right Ctrl as Right Altctrl:menu_rctrl      Menu as Right Ctrlctrl:ctrl_ralt       Right Alt as Right Ctrlcaps:ctrl_modifier   Make Caps Lock an additional Control but keep the Caps_Lock keysymaltwin:ctrl_win      Control is mapped to Win keys (and the usual Ctrl keys)altwin:ctrl_alt_win  Control is mapped to Alt keys, Alt is mapped to Win keysterminate:ctrl_alt_bksp Control + Alt + Backspace

可以看到“ctrl:nocaps”可以实现我们想要的功能：把caps变为另一个ctrl键。
接下来就是在哪里修改映射规则：

方法一： dconf
dconf write /org/gnome/desktop/input-sources/xkb-options "['ctrl:nocaps']"

方法二：dconf-editor
安装dconf-editor，打开后根据路径/org/gnome/desktop/input-sources找到xkb-option，修改其内容为['ctrl:nocaps']
