If you don’t want to use a user interface to change the effect of Ctrl+Alt+Backspace in any flavour of Ubuntu you can follow these steps:
1) Install the “dontzap” package
sudo apt-get install dontzap
2) Open Terminal or Konsole and type:
sudo dontzap --enable
or
sudo dontzap --disable
Where “disable” means that Ctrl+Alt+Backspace restarts the xserver while “enable” means that it won’t.
I’ll post something on the GTK UI when it’s ready.
As you might have noticed already, X.org no longer ships with the DontZap option set to False by default i.e. pressing Ctrl+Alt+Backspace won’t restart the xserver any longer. At the UDS we discussed on how to deal with this change and we came to the conclusion that Ubuntu and Kubuntu would deal with this change in different ways. I worked on both the implementations.
This blog post is about the Kubuntu implementation. Click on the thumbnails to see the screenshots in their full size.
1) Install the “dontzap” package (hopefully this step can be skipped in the future):
sudo apt-get install dontzap
2) Launch “systemsettings”
3) select the “Display” module
4) click on the checkbox which says “Ctrl+Alt+Backspace restarts the xserver” and press the apply button:
5) insert your password
And that’s it.
I’ll blog more about the way you can do it in Ubuntu and from the command line.
