| The key combination Ctrl-Alt-Backspace to kill the X server has been [http://cgit.freedesktop.org/xorg/xserver/commit/?id=9d135ac10a7374c7ccda705f1eeb02cc53076c34 disabled by default] as a decision of the upstream Xorg project. You can change the default by adding the following section to xorg.conf file. If one does not exist, you can create it manually at /etc/X11/xorg.conf using a text editor and Xorg will honor that setting.

| <pre>Section "ServerFlags"
| |
| Option "DontZap" "false"
| |
| EndSection</pre>
| |
| | |
| If you use kickstart or want to use scripts to change this setting automatically across multiple systems, you can use the following snippet
| |
| | |
| <pre>%post
| |
| | |
| grep -q -s DontZap /etc/X11/xorg.conf
| |
| append=$?
| |
| if [ $append -ne 0 ]; then
| |
| cat >> /etc/X11/xorg.conf << EOF
| |
| Section "ServerFlags"
| |
| Option "DontZap" "false"
| |
| EndSection
| |
| EOF
| |
| fi
| |
| | |
| %end</pre>
| |
| | |
| The Xorg project has changed the default DontZap setting to "true" after complaints from desktop users that accidentally hit Ctrl+Alt+Backspace when trying to type Alt+Backspace, Ctrl+Backspace, or Shift+Backspace, or who had StickyKeys enabled. Ctrl+Alt+Backspace is also a keyboard shortcut for deleting certain expressions in C and Java modes in Emacs.
