[Bug 1060767] Re: Ctrl-PrintScrn and Alt-SysRq are killing the processes in console

[C de-Avillez]

Thank you for opening this bug and helping make Ubuntu better. First of
all, this is not a coreutils issue, so I am closing the task for it.
This was well explained in the coreutils upstream bug.

Secondly, you have not provided any data about your Ubuntu version.
Generically, it would be better if you opened bugs using 'ubuntu-bug'
instead -- 'ubuntu-bug' will collect some data from your system,
including Ubuntu version.

** Changed in: coreutils (Ubuntu)
       Status: New => Invalid

Title:
  Ctrl-PrintScrn and Alt-SysRq are killing the processes in console

Status in “binutils” package in Ubuntu:
  New
Status in “coreutils” package in Ubuntu:
  Invalid

Bug description:
  Affected keys (on key release time):
  - Ctrl+PrintScrn
  - Alt+SysRq
  - Win+PrintScrn
  - and similar like Alt-SysRq + 1-4,7-9,0 (which are ignored by kernel, even these are documented in kernel sysrq.txt)
  Exceptions: Alt+SysRq+5,6 (because these are only digits which are handled by kernel)

  Steps to reproduce:

  1. Change to the text console (Ctrl-Alt-F1).
  2. Log in.
  3. Run: sleep 100 (or any other command like: cat, head, etc.)
  4. Press Ctrl-PrintScrn or Alt-SysRq  (and release the key).
  5. Process get killed by: ^\Quit (core dumped)

  What I expect is to change my log level  of kernel messages by Alt-SysRq + 0-9 as documented at http://kernel.org/doc/Documentation/sysrq.txt
  Or use any other shortcuts using PrintScrn key.

  Normally the only keys which should be killing the processes are:
  Ctrl+4 and Ctrl+\ but not the other.

  Originally I've reported it here:
  http://debbugs.gnu.org/cgi/bugreport.cgi?bug=12478
  But this doesn't happens on other distributions.
  So I was advised to report key mapping issue to my software distribution community.
