Every keyboard has a SysRq button. On most, it is shared with PrtScrn. However, I've also seen it shared with either an F key or ScrollLock or by itself. Also, I've seen laptops where you had to hold the Fn key to get a key that acts like SysRq. I guarantee you've got one, although I suppose it might not be labeled SysRq at all. > > E, I, S, U, B > > > > so everything is killed, and nothing trying to write to disk, when > > unmounting them. > > Hmm, I do not think you understand, when I exit X/kde the entire system > is latched up tight.

Those are handled directly by the kernel at a fairly high priority. I've had everything else be ignored, including C+A+Del, and had Alt+SysRq save my filesystems. It is possible that you might not see anything happen after E, I, S, and U, especially if you were previously in X, since the kernel is trying to write to the text-mode console but things are happening unless your kernel has crashed. All other keystrokes travel to user-space to be processed, so if your kernel is busy, they won't do anything. -- Boyd Stephen Smith Jr. ,= ,-_-. =.
