    Enable the ctrl-alt-backspace combination

    Linking > Alpha-2 >> JauntyJackalope/TechnicalOverview
    Known Issues:
    ...
    Ctrl-Alt-Backspace is now disabled, to reduce issues experienced by users who accidentally trigger the key combo. Users who do want this function can enable it via the DontZap option in xorg.conf. A GUI tool to simplify setting xorg.conf options is under development and will be available in a later Alpha release.
    ...

    Manual

    > xorg.conf manual page
    Serverflags Section

    The ServerFlags section is used to specify some global Xorg server options. All of the entries in this section are Options, although for compatibility purposes some of the old style entries are still recognised. Those old style entries are not documented here, and using them is discouraged. The ServerFlags section is optional, as are the entries that may be specified in it.

    Options specified in this section (with the exception of the "DefaultServerLayout" Option) may be overridden by Options specified in the active ServerLayout section. Options with command line equivalents are overridden when their command line equivalent is used. The options recognised by this section are:
    ...
    Option "DontZap" "boolean"
    This disallows the use of the Ctrl+Alt+Backspace sequence. That sequence is normally used to terminate the Xorg server. When this option is enabled, that key sequence has no special meaning and is passed to clients. Default: off.
    ...

    Enabling

    Adding xorg.conf:
    Code:
    Section "ServerFlags"
	Option		"DontZap"	"off"
EndSection
    Xorg.0.log should tell:
    Markers: (--) probed, (**) from config file, (==) default setting,
    (++) from command line, (!!) notice, (II) informational,
    (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
    (==) Log file: "/var/log/Xorg.0.log", Time: Sat Dec 20 12:51:17 2008
    (==) Using config file: "/etc/X11/xorg.conf"
    (==) No Layout section. Using the first Screen section.
    (**) |-->Screen "Default Screen" (0)
    (**) | |-->Monitor "Configured Monitor"
    (**) | |-->Device "Configured Video Device"
    (**) Option "DontZap" "off"
    Seems to work !

    Re: Enable the ctrl-alt-backspace combination

    Thank you rog.

    It doesn't keep me from wondering why the gods that be keep making decisions for us and at the same time I can't log out with kmenu / lancelot "leave" of right click "leave".

    I have the same issue with II by the way

    I do not want to use:
    Code:
    sudo reboot
    so ctrl-alt-backspace is my only option short of a hard shutdown.

      Lot of opinions > POLL: Do you want to have CTRL-ALT-BACKSPACE disabled in Jaunty?


      and at the same time I can't log out with kmenu / lancelot "leave" of right click "leave".
      Have you tried with an external program ? I did have a problem that the shutdow/restart just logged out. > Topic: KDE 4.2 RC: Shutdown computer withou logging out to KDM. Kshutdown was a workaround - still using it as it works (not silly countdowns when you press "LEAVE").

        Lot of opinions Grin > POLL: Do you want to have CTRL-ALT-BACKSPACE disabled in Jaunty?
        Thank you rog, guess what I voted for

        Anyway I will try the mepis version of kde4.2 first and see if they have a similar issue.

        The thing is that it works perfectly in kde-nightly (neon) so I wonder if it is a kubuntu issue.

        JJ is alpha.
        But II is a "finished" release and I get the same behavior there as well. Do not know why.
        Regardless of :
        http://www.nabble.com/KDE-4.x-and-th...d19467178.html

        I will try kshutdown on JJ but find it a bit of a cumbersome way of doing something that should "just work" in a "released" distro ie. II.

        It works in JJ but I can't see it with the intrepid ppa's

        Edit:This does not work with II:
        Package: kshutdown (1.0.2-1ubuntu1)

          fintan,
          you can shutdown this way too
          Code:
          sudo shutdown -P 00
          basicly its shutdown and poweroff now
          hope that helps for the time being

            Re: Enable the ctrl-alt-backspace combination

            Thanks silthlord I'll try that. Still seems a bit well, boring. This should be working.

            As I said it works in kde-nightly.

            Lets see how mepis fairs

            Edit: I took the plunge and tried kshutdown in Intrepid using the jaunty ppa?s.
            It seems to be behaving itself. For now

              dontzap - DontZap X Utility

              SYNOPSIS

              DESCRIPTION

                Again ROG, Thanks! I'll definitely need to know this when I move to JJ.

                  Re: Enable the ctrl-alt-backspace combination

                  Also, when the dontzap package is installed, there should be a GUI checkbox to enable zapping in SystemSettings>Display

                  You can also use Alt+SysRq+K in place or Ctrl+Alt+Backspace (It's not as fast as Ctrl+Alt+Backspace , but should work even when Ctrl+Alt+Backspace doesn't)

                    Good to know, thank you ! (though - i'm a bit conservative - i'm still using text editor to modify the xorg.conf )

                        This works for me ...yippee!

                        Also did not know about the Alt+SysRq+K option...is that knew or something that idiots like me did not pick up on before?

                        Anyway...the dontzap update works and I have now a gui with a clickable option for enabling etc the Ctrl+Alt+Backspace
