Re: problems with system-config-display and crtl-alt-backspace

Suvayu and Tim:

A very good explanation of the differences and what to expect from each.

Suvayu is correct in understanding my emails that I am running tcsh as that is the shell I am most familiar with thanks to work environments. Given the info that I have gotten here, I will take a stab at finding out from our sysAdmins whether there is anything similar in tcsh. You can probably tell that, being a tcsh user, the concept of a "_profile" is a new one to me ... more learning on my part is in order now that you've pointed me in right direction.

If the OP is interested, the command line way to do this would be to
have one of your login scripts like ~/.bash_profile say,

setxkbmap -option terminate:ctrl_alt_bksp


Thanks, this is interesting. So it is in .bash_profile and not .bashrc?
Is there a similar way to do in either cshrc or, preferably, tcshrc?

~/.bash_profile gets sourced by any "well behaved" desktop environment when ever you login. In my experience XFCE and WindowMaker does this. (I don't use Gnome/KDE as often, so can't comment on them).

~/.bashrc gets sourced when ever you open an interactive shell, maybe by opening a terminal emulator or login in remotely.

This means whenever you login remotely both ~/.bash_profile & ~/.bashrc gets sourced. However if you open a terminal emulator like gnome-terminal or xterm only your ~/.bashrc gets sourced.

So ideally, (As Tim said in a later post) your environment variables should be defined in your ~/.bash_profile where as your aliases and functions should be defined in ~/.bashrc.

What I say is true assuming your login shell is bash. Since you asked about csh or tcsh, as far as I understood from a quick look at the respective manpages (section: startup and shutdown) they behave differently. There is no file corresponding to ~/.bash_profile for either of them. (maybe this is how C-shells behave?) However ~/.tcshrc or ~/.cshrc does get sourced (in that order). So you can define this in one of those files and see whether this works.
