You sure you didn't mean Ctrl-Backslash? That generates
a SIGQUIT (3). And it doesn't appear to generate a core
dump in my case, though that may be because I have ulimit
-c 0. Setting ulimit -c 8192 (the number is maximum size
of the core file in blocks) allows me to dump a core file.
Note that this can be done in a console or a X terminal.
Of course the core is for the program "sleep"; not horribly
useful. :-)
Ctrl-Alt-Delete does nothing, although vi seems to respond
to the Delete. Ctrl-Alt-Backspace will force X down --
handy under certain conditions.
And of course Ctrl-Alt-F1 through F6 will switch the display from X to
a console. (Depending on configuration, Ctrl-Alt-F7 through
Ctrl-Alt-F12 might also work.
