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

[kenorb]

Unfortunately ubuntu-bug doesn't work for me, because I'm behind of proxy, which I've reported separate bug report about it.
I don't see why the ticket is changed to Invalid, it takes few minutes to ask for more information.
I assume it's present in most of the Ubuntu distributions.

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.
