sorry for my poor explanation.

1) build kernel with DDB and boot with the kernel
at this time, Esc + Alt + Ctrl breaks into kdb.

on the console
2) export DISPLAY=foreign:0            # pidgin requires X server
3) gdb pidgin 
4) and "run" command of gdb

and
After "kernel trap 9 with interrupts disabled" message appeared on the console,
nothing happened, any keys (including Esc + Alt + Ctrl) were ignored.
