Ctrl+Alt+Backspace is usually enabled by default under X, and is a keyboard shortcut that forcefully kills the current X server. This can lead to data loss by users if accidentally pressed. This commit introduces a new option, services.xserver.enableCtrlAltBackspace, that is *disabled* by default. If set to true, the previous behavior can be restored. A similar decision was made by the Ubuntu team, and is documented here: https://wiki.ubuntu.com/XorgCtrlAltBackspace
