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

[Joseph Salisbury]

Would it be possible for you to test the latest upstream kernel?  Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.8 kernel[0] (Not a kernel in the daily directory) and install both
the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.  
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

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

Status in “coreutils” package in Ubuntu:
  Invalid
Status in “linux” package in Ubuntu:
  Incomplete

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.
