Hello

I am using OpenSuse 12.1 with XFCE.
I don’t see the ENABLE_SYSRQ in the sysconfig editor and /etc/sysconfig/sysctl doesn’t exist …
What do I do ?
Thank you for your support !

Why can`t I use key? But such commands “echo p > /proc/sysrq-trigger” is useful.

no, you don’t need ctrl. _Fn key might be required though. prt screen feature should work with print key alone. no need for alt. although, again, some of us will need Fn key

@Robin — No, ‘Ctrl’ isn’t required.

I’ve used the ‘Alt+SysRq+r e i s u b’ sequence before on a couple of different linux systems. Usually because it wouldn’t respond to other nicer shortcuts like Ctrl+Alt+Backspace (kill X server) or Ctrl+Alt+Delete (restart computer or open shutdown dialoge, depending on your environment).
I have also gotten into Really bad situations where even ‘Alt+SysRq… didn’t work, which is sad because I have to hard-shutdown the computer.

Are you quite sure you don’t need to press ‘Ctrl’, too? All previous explanations of this feature I have seen require ‘Ctrl’ + ‘Alt’ + SysRq’ + additional keys. ‘Alt’ + SysRq’ should, thanks to the function of the Print Screen feature, only lead to a screenshot to be dumped.

In addition, most notebook users will additionally have to press the Fn key to be able to access SysRq. Yes, a third hand comes in handy.
