From: John Magolske on 6 Mar 2010 17:10 I'd like to be able to use Ctrl-Alt-BS to kill X, but can't get it to work. I searched around and tried a bunch of things: In /etc/X11/xorg.conf : ... Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbOptions" "compose:rwin" Option "XkbOptions" "terminate:ctrl_alt_bksp" EndSection ... Section "ServerFlags" Option "DontZap" "off" EndSection Added to /etc/default/console-setup (then rebooted the machine): XKBOPTIONS="terminate:ctrl_alt_bksp" Added this line to /etc/default/keyboard : XKBOPTIONS="terminate:ctrl_alt_bksp" Added this line to ~/.xsession and ~/.xinitrc : setxkbmap -option terminate:ctrl_alt_bksp .... All to no avail. The *only* way I can get Ctrl-Alt-BS to Zap X is to first open a terminal after launching X and manually enter: setxkbmap -option terminate:ctrl_alt_bksp Isn't this supposed to happen automatically when launching X if that line is in ~/.xinitrc ? And Alt-SysRq-K is not what I'm looking for -- that will kill X, but just leaves a dead VT that I can't switch out of. This is on sid, with the latest xserver-xorg-core.

I searched around and tried a bunch of things: > [ ... bunch of things ... ] Finally found something that works, this line in ~/.xmodmap : keycode 22 = BackSpace Terminate_Server Now Ctrl-Alt-BS will Zap X. And it is this alone that does it -- I undid all the other afore-mentioned bunch of things. Not sure I entirely understand the above keycode command ... I would think it means 'Shift-BS', but 'Shift-BS' has no effect. I got the clue from http://bbs.archlinux.org/viewtopic.php?pid=602885#p602885 which suggested: keycode 22 = BackSpace BackSpace Terminate_Server But that has no effect, had to remove one 'BackSpace' from that line. In any case, setting 'Zap' in xmodmap with 'Terminate_Server' seems to make more sense, as it allows the user to set a key combo that suits them best (ie, least likely to be hit by accident).

It was the commenting out of this line that allowed Ctrl-Alt-BS to effectively Zap X ... What I've finally arrived at, to remap Zap to something else is as follows: in ~/.xmodmap : ! Make Control_R the Mode_switch key add mod2 = Mode_switch keycode 105 = Mode_switch ! make Shift-Control_R-Delete Zap X keycode 119 = Delete Delete Delete Terminate_Server Then, in /etc/X11/xorg.conf set "DontZap" to "off" : Section "ServerFlags" Option "DontZap" "off" #disable <Crtl><Alt><BS> (server abort) EndSection Or just comment out the above. Or leave it out entirely, but do not set it to "on". Now X will be Zapped by pressing Shift-Control_R-Delete, a somewhat more unlikely key-press combo (for me anyways). BTW, I found this guide to be very helpful in understanding xmodmap: Some hints about xmodmap(1) and the X11 keyboard model http://www.in-ulm.de/~mascheck/X11/xmodmap.html Regards, John -- John Magolske http://B79.net/contact -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
