ksnapshot sounds like something that might respond to a PrtSc keypress. This is a sign that you aren't using Alt, so what you've really done is PrtSc-D. Didn't I tell you already to stop using "SysRq" to descibe key combinations that don't include Alt? WITHOUT ALT IT IS NOT A SYSRQ KEY. Got that yet? Reread it until you do. > When I press Control-SysRq-D, my session is getting logout. Well, Ctrl-D is EOF and PrtSc+D is a meaningless combination (as meaningless as pressing D and Q at the same time, it's anyone's guess which will take precedence) > When I press Control-Alt-SysRq-D my processes are killed. Too many keys there, I can't guess what they're all doing. Get rid of the Control. And make sure your kernel has CONFIG_LOCKDEP, otherwise the Sysrq+D function is disabled. Also, based on the Subject line, you think "SEGV" is a synonym for core dump. Stop thinking that. Nothing segfaulted. SIGSEGV is one of many signals that can cause a core dump. SIGQUIT is another one. -- Alan Curry
