idea快捷键太多， 今天写代码i的时候一不小心按下control+alt+backspace，导致X server重启。
在没做好心里准备的情况下重启的代价往往很大,所以我决定禁用重启X server快捷键.google之发现都是ubantu。。。。
下面主要说说我是怎么找到禁用这个快捷键方式过程吧
1.首先想到的命令是xface+TAB自动提示（因为我 xfce4-keyboard-settings 定义过快捷键）
[[email protected] ~]# xfce4- xfce4-about xfce4-clipman-settings xfce4-mixer xfce4-popup-clipman xfce4-power-manager-settings xfce4-settings-editor xfce4-accessibility-settings xfce4-display-settings xfce4-mouse-settings xfce4-popup-directorymenu xfce4-screenshooter xfce4-settings-manager xfce4-appearance-settings xfce4-keyboard-settings xfce4-notifyd-config xfce4-popup-windowmenu xfce4-session xfce4-taskmanager xfce4-appfinder xfce4-kiosk-query xfce4-panel xfce4-power-information xfce4-session-logout xfce4-terminal xfce4-clipman xfce4-mime-settings xfce4-popup-applicationsmenu xfce4-power-manager xfce4-session-settings xfce4-volumed
然后发现 xfce4-keyboard-settings并不支持禁用一些系统快捷键
2.查看xfce的配置文件，如下所以直接进入xfce-perchannel-xml目录
[[email protected] ~]# tree /root/.config/xfce4/ /root/.config/xfce4/ ├── desktop │ └── icons.screen0-1904x1033.rc ├── help.rc ├── helpers.rc ├── panel ├── terminal │ └── terminalrc ├── xfconf │ └── xfce-perchannel-xml │ ├── displays.xml │ ├── keyboard-layout.xml │ ├── keyboards.xml │ ├── thunar.xml │ ├── xfce4-appfinder.xml │ ├── xfce4-desktop.xml │ ├── xfce4-keyboard-shortcuts.xml │ ├── xfce4-mixer.xml │ ├── xfce4-panel.xml │ ├── xfce4-session.xml │ ├── xfwm4.xml │ └── xsettings.xml └── xfwm4
3.按关键字搜索xfce-perchannel-xml目录(因为我需要找的是control+alt+back)
如下图
很明显快捷键定义就在/xfce4-keyboard-shortcuts.xml文件中，但我仔细找了找， 里面还是没有发现
4. 我只好换了种思路,首先找到, xorg.conf，输出所有的文本文件，刷选出带有alt的字符串
[[email protected] ~]# locate xorg.conf | xargs file | grep "ASCII text" | awk -F":" '{print $1}' | xargs cat | grep "alt"
#Option "XkbOptions" "terminate:ctrl_alt_bksp"
# Option "XkbOptions" "compose:rwin,terminate:ctrl_alt_bksp"
# Waltop tablets
Identifier "Waltop class"
# (although not every card will support every resolution).
很明显配置就在ctrl_alt_bksp这一行.所以只需要找到这份文件就可以了(/usr/share/X11/xorg.conf.d/90-keyboard-layout.conf).
[[email protected] ~]# locate xorg.conf | xargs file | grep "ASCII text" | awk -F":" '{print $1}'
/usr/share/X11/xorg.conf.d/50-vmmouse.conf
/usr/share/X11/xorg.conf.d/10-evdev.conf
/usr/share/X11/xorg.conf.d/50-synaptics.conf
/usr/share/X11/xorg.conf.d/90-keyboard-layout.conf
/usr/share/X11/xorg.conf.d/50-wacom.conf
/etc/X11/xorg.conf
/etc/X11/xorg.conf-vesa
5.编辑/usr/share/X11/xorg.conf.d/90-keyboard-layout.conf文件,注释掉ctrl_alt_bksp,重启即可
[[email protected] ~]# cat -n /usr/share/X11/xorg.conf.d/90-keyboard-layout.conf
1 Section "InputClass"
2 Identifier "keyboard-all"
3 MatchIsKeyboard "on"
4 MatchDevicePath "/dev/input/event*"
5 Driver "evdev"
6 Option "XkbLayout" "us"
7 #Option "XkbVariant" ""
8 #Option "XkbOptions" "terminate:ctrl_alt_bksp"
9 EndSection
