I've seen on this group some time back a few ways, or at least more than 1 as I recall to retain the ability to leave X with Ctrl+Alt_+BKSPC.
I'm not finding it now readily. Can someone tell me where that setting may be made. If it has something to do with new way of starting X where we don't need an xorg.conf file... I should say that I still use /etc/X11/xorg.conf (In case that makes a difference) I find trying to leave X with the `logout' menu item provided on the Xfce4 destop, that if X has been running a while is seems to take a very long time to get out of X that way, and possibly not only long but even ever, short of: kill -TERM `ps wwaux|awk '/X.*\-nolisten tc[p]/{print $2}'` Or killing the pid some other way. The Ctrl+alt+bkspc was a much nicer fallback.
