X Window System (Graphics)

This section contains information related to the X Window System implementation, Xorg, provided with Fedora.

X server

The key combination Ctrl+Alt+Backspace to kill the X server has been removed from the default XKB maps. To restore it, you must enable the xkb option terminate:ctrl_alt_bksp. From the main menu, select System > Preferences > Keyboard. In the Keyboard Preferences dialog, select the Layout tab, then select Layout Options. Select Key sequence to kill the X server and then tick the checkbox for Control + Alt + Backspace.

Alternatively, run the following command to enable the key combination temporarily:

setxkbmap -option "terminate:ctrl_alt_bksp"

The package fedora-setup-keyboard automatically merges this XKB option at X server startup, making the Ctrl+Alt+Backspace key combination functional in gdm, or if the server is started without the GNOME desktop environment. It is deactivated once GNOME applies the user-configured keyboard layout unless the user has enabled it in the preferences menu as detailed above.
