Ctrl-Alt-Backspace

Ctrl-Alt-Backspace

[Jack Tanner]

Er, so Ctrl-Alt-Backspace kills the X-server (quite efficiently, and 
with no confirmation). This is bad (for example, when Ctrl-Alt-Backspace 
happens to match an Emacs incantation).

Since Xwin plays nicely with the system tray icon for exiting, is there 
any reason to listen for Ctrl-Alt-Backspace? I can think of two reasons 
-- compatibility with XFree86 convention across platforms, and 
preserving keyboard accessibility. I'm not sure that either one is very 
important here.

The least disruptive fix is probably to make Ctrl-Alt-Backspace invoke 
the same confirmation dialog that the system tray icon invokes.

Thanks,
JT

I don't know, but can't you remap it rather than changing the default 
X-server behavior?  Certainly
seems like something that should be user-remapable for kiosk type 
installations....can't have just
everyone going around killing off your kiosk, ya know.

Well, technically, adding "-nounixkill" to the XWin.exe parameter list
should do it, but it doesn't work for me.  When I open an XWin session on
a Win2k SP3 machine, Ctrl-Alt-Backspace still happily kills the server,
even with -nounixkill.  The command I used to start the X server was

XWin :1.0 -nounixkill

(since I have Exceed running on display :0.0) and pressed
Ctrl-Alt-Backspace in the window once the screen appeared to have
initialized (after a minute or so).  /tmp/XWin.log is attached, and the
versions of the relevant (IMO) installed software are below.  Please let
me know what further information I can provide (or experiments I could
try) to help diagnose the problem.

Of cause you can. Just remove the binding to Terminate_Server from keycode
22.

 xmodmap -e "keycode 22 = BackSpace"

Why not. The kiosk should be restarted then automaticly. It is better than
having no possiblity to reset a screwed session.

add the option -unixkill. This will ask you indstead of just killing the
server.

The problem is that the 4.3 release of XFree binds the killing of the server
to the keycode "TerminateServer". There is currently no way to override this
but you can remove that binding from keycode 22.

 xmodmap -e "keycode 22 = BackSpace"

Thanks, this worked like a charm.

This, however, not only didn't change anything (Ctrl-Alt-Backspace still
exited X), but also crashed XWin.exe.  I doubt the stack dump is of any
use with a non-debug version of XWin, but I can provide it if people
request, as well as the corresponding XWin.log (which doesn't contain any
details of the crash).  I believe I've also posted the details of my setup
earlier in this thread.  To reproduce the problem, run

$ XWin :1.0 -unixkill &

Try exiting it with Ctrl-Alt-Backspace, and press "Cancel".

$ xmodmap -display :1.0 -e "keycode 22 = BackSpace"

Try exiting again with Ctrl-Alt-Backspace, and press "Exit".

XWin will crash with a segfault.  I'd be willing to try a debug version
and get a real stack trace if developers can't reproduce it.

I can't reproduce it so I'd be glad if you could do so.

Alexander,

Could you or Harold please post a debug snapshot somewhere?  I don't have
a build tree set up, and the problem is relatively minor and doesn't
affect me too much, so I don't have the motivation of setting one up just
now.  I will try the debug snapshot, though, and post the stack trace.

Alexander,

Thanks.  However, your snapshot doesn't seem to react to the "Exit"
message or the Alt-F4 key combination (-[no]winkill don't help).  It only
reacts to Ctrl-Alt-Backspace if neither -nounixkill nor -unixkill is
specified, and then X simply exits.  No wonder you couldn't reproduce the
problem.  I'm attaching the logs from your build for the two sequences
below:

1) ./XWin :1.0 -unixkill &
   Press Ctrl-Alt-Backspace 5 times
   kill -1 %1
   kill -2 %1

2) ./XWin :1.0 &
   Press Ctrl-Alt-Backspace

HTH.  Please let me know if you'd like me to try another debug build, one
that has the -[no]unixkill functionality enabled.
	Igor

I noticed this too but thought it was a problem when running in gdb. So you'll
have to ask Harold for the debug build. I'm quite busy with merging the changes

Looks clean to me... I will test it tonight and release it if possible.

I have a feeling that this might have some effect on the "keyboard 
doesn't work" problem that people have been encountering.

Takuma,

Thanks for the patch.  It has been applied and released as 
XFree86-xserv-4.3.0-26.

Alexander or Kensuke - Could you apply this patch to the freedesktop.org 
tree?  Thanks in advance.

Since I originally reported this bug, I'm happy to confirm that it seems
to be fixed.
