Ctrl-Alt-Backspace doesn't work
From Salix OS
HAL was depreciated in Salix OS 14. Therefore this article applies only to Salix OS version(s) 13.37 and earlier.
In recent xorg releases the use of the Ctrl-Alt-Backspace key combination to zap X has been removed. You can now use the Alt-PrintScreen-k key combination, which kills the current session rather than the x server though.
If you want to get the Ctrl-Alt-Backspace key combination working, you can edit the /etc/hal/fdi/policy/10-keymap.fdi hal configuration file, find the line that refers to "input.xkb.options" and edit it like this:
<merge key="input.xkb.options" type="string">terminate:ctrl_alt_bksp</merge>
If you already have some keyboard switching options in that line just add the terminate rule next to it, using a comma to separate the two rules.
