Every keyboard has a SysRq button. On most, it is shared with PrtScrn. |
15 |
However, I've also seen it shared with either an F key or ScrollLock or by |
16 |
itself. Also, I've seen laptops where you had to hold the Fn key to get a |
17 |
key that acts like SysRq. |
18 |
|

I guarantee you've got one, although I suppose it might not be labeled |
20 |
SysRq at all. |

Please *try* the Alt+SysRq instructions if you haven't already. Those are |
32 |
handled directly by the kernel at a fairly high priority. I've had |
33 |
everything else be ignored, including C+A+Del, and had Alt+SysRq save my |
34 |
filesystems. It is possible that you might not see anything happen after |
35 |
E, I, S, and U, especially if you were previously in X, since the kernel |
36 |
is trying to write to the text-mode console but things are happening |
37 |
unless your kernel has crashed. |
38 |
|
39 |
All other keystrokes travel to user-space to be processed, so if your |
40 |
kernel is busy, they won't do anything. |
