5. Then, 'ctrl-alt-backspace' and voila... X is down and my console is there, opened for me.
Working as designed. XFree is just following the X Consortium here - X servers have used control-alt-backspace as a "shutdown now" hotkey at least as far back as X11.1 or maybe even X10.4, 15 years ago. If this is a problem in your environment: 1) dont use 'startx', but use 'gdm' or something to manage logins. This way, when the X server exits, you go back to the login screen. 2) 'man 5 XF86Config' and read this in the 'Serverflags section': Option "DontZap" "boolean" This disallows the use of the Ctrl+Alt+Backspace sequence. That sequence is normally used to termi- nate the X server. When this option is enabled, that key sequence has no special meaning and is passed to clients. Default: off.
