What I miss on my rpi with xbian is response to ctrl-alt-backspace.
I tried to use dpkg-reconfigure keyboard-configuration but unfortunately
the usual option which lets you configure ctrl-alt-backspace is not presented. Does someone here now how to do it?
The reason I want it is for those times I did not take note of the ip-address and the rpi hangs, the only thing I can do then is remove the power but this can lead to file system corruption, ctrl-alt-back space could give me the choice to properly halt the system without damage.

thanks in advance

How should keyboard interaction work if the RPi hangs?

When a linux system hangs, depending on how bad the situation is two things you sometimes can do is: log in remotely but then you need to know what ip-number the system has or stop the gui via ctrl-alt-backspace and halt the system from the command prompt, I suppose the rpi is not different concerning this matter.

I believe Raspbian did attach key combinations with a program called triggerhappy, maybe you should look at that. Let us know when you found it.

I tried first to edit /etc/default/keyboard with the following line:
XKBOPTIONS="terminate:ctrl_alt_bksp"
unfortunately this didn't work

then I installed:
dpkg -i triggerhappy_0.3.4-2_armhf

however I don't know how to make triggerhappy use ctrl-alt-bksp

someone here any idea how?

This is how they do it in raspi-config:

I suppose you are pointing to this line:
thd --dump /dev/input/event* | grep -q "LEFTSHIFT\|RIGHTSHIFT"

unfortunately I don't know how to make the system recognize
ctrl-alt-bksp from this info :-(

My knowledge of triggerhappy is as much as yours. I only knew it was used in that file. Just do some research and experimentation.

I tried /etc/init.d/triggerhappy start
then looked what would ctrl-alt-bksp would produce using thd --dump /dev/input/event* but nothing comes out of it unfortunately...
