Fair enough but I wasn't really suggesting it, more just pointing out that if X died the buffers still wouldn't be flushed ifStan Bubrouski wrote:That seems like a pretty unhelpful solution. Say the system crashes? Or KDE orYou'd think that if someone could force a timed crash on the machine intended to save a small amount of data to buffers on the video card, that you'd probably have many more problems on your hands than that.X crash? The same problem will still exist.With this solution someone could intentionally crash your machine to avoid those routines from running. I'm not trying to put you down or anything, in fact I probably know less about video related stuff than most on the list, this just doesn't seem like the best way to do it. I have no better suggestions, I'll leave this one tothe experts.
that is indeed the problem.
Not to mention that when a machine crashes, most people don't just walk away and say "oh well". They usually restart the machine to either continue what they were doing, or to make sure that it starts up properly. We're not really talking about remote information disclosure, we're talking about someone being right at the terminal.
Much of the internet is made up of unattended machines...
My thought on that is that the only way that a crash would work for this is if the person were looking over your shoulder. At that point, why would they need to crash the system?I simply used a lame example to illustrate a point. Think of computer labs and offices. If my lab machine crashes I move to another... and someone else may sit down and see what I was just doing.
Plus if you work in an office and crash someone's machine while they are away from it you can still start it up and watch the screen before GDM or whatever kick in. Really though like I said I really just wanted to point out that X not shutting down properly bypasses the proposed solution, thats all.
Likewise, not trying to put you down... just pointing out my observations.
Ditto :-D -sb
