Xface: Disable control + alt + backspace shortcuts

Xface: Disable control + alt + backspace shortcuts

There are too many idea shortcuts. When I wrote code today, I accidentally pressed control + alt + backspace, causing X server to restart.

In the absence of preparation, the restart cost is often very high, so I decided to disable the restart X server shortcut key. google found that ubantu ....

 

The following describes how to disable the shortcut key.

 

1. The first command to come up with is the xface + TAB automatic prompt (because I have defined a shortcut for xfce4-keyboard-settings)

 

[root@jjy ~]# xfce4-xfce4-about                   xfce4-clipman-settings        xfce4-mixer                   xfce4-popup-clipman           xfce4-power-manager-settings  xfce4-settings-editorxfce4-accessibility-settings  xfce4-display-settings        xfce4-mouse-settings          xfce4-popup-directorymenu     xfce4-screenshooter           xfce4-settings-managerxfce4-appearance-settings     xfce4-keyboard-settings       xfce4-notifyd-config          xfce4-popup-windowmenu        xfce4-session                 xfce4-taskmanagerxfce4-appfinder               xfce4-kiosk-query             xfce4-panel                   xfce4-power-information       xfce4-session-logout          xfce4-terminalxfce4-clipman                 xfce4-mime-settings           xfce4-popup-applicationsmenu  xfce4-power-manager           xfce4-session-settings        xfce4-volumed

Then we found that xfce4-keyboard-settings does not support disabling some system shortcuts

 

2. view the xfce configuration file, as shown in the following figure, directly go to the xfce-perchannel-xml directory.

[root@jjy ~]# 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. Search for the xfce-perchannel-xml directory (Because I need to find control + alt + back)

 

 

For example

Obviously, the shortcut key definition is in the/xfce4-keyboard-shortcuts.xml file, but I looked for it carefully, it is still not found

 

4. I had to change my mind. First, find xorg. conf, output all text files, and click the string with alt.

 

[root@jjy ~]# 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).

 

Obviously, the configuration is in the ctrl_alt_bksp line. So you only need to find this file (/Usr/share/X11/xorg. conf. d/90-keyboard-layout.conf).

 

[root@jjy ~]# 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. Edit the/usr/share/X11/xorg. conf. d/90-keyboard-layout.conf file, comment out ctrl_alt_bksp, and restart.

 

 

[root@jjy ~]# cat -n /usr/share/X11/xorg.conf.d/90-keyboard-layout.conf     1Section "InputClass"     2Identifier "keyboard-all"     3MatchIsKeyboard "on"     4MatchDevicePath "/dev/input/event*"     5Driver "evdev"     6Option "XkbLayout" "us"     7#Option "XkbVariant" ""     8#Option "XkbOptions" "terminate:ctrl_alt_bksp"     9EndSection
