That SIGKILL after SIGTERM was just a precaution. I felt the greeter
should be able to kill Onboard dead in case anything unforeseen happens.
Fixing this bug better not prevent you from logging in, I thought.
However, in my tests Onboard always shut down rapidly on SIGTERM. It's

Enter hangs when using it entering password with onboard in lightdm
To manage
OK, I have a branch that merely turns the SIGKILL into SIGTERM (a
simpler change this late in the cycle). I also uploaded it as a patch
to Ubuntu.
Thank you marmuta and Francesco for walking me through this, as I
couldn't reproduce. I'm eager to hear if 12.10.4-0ubuntu3 will fix this
for you.

unity-greeter 12.10.4-0ubuntu3 seems to have fixed the issue: I logged
out and in several times, and even restarted the computer three times
without the issue appearing again. However, as the problem did not occur
on every login, I cannot tell for sure whether it is really fixed.
I am marking
Unity-greeter 12.10.4-0ubuntu1 is now available in the repository and
after installing it, the problem is still occurring here (after shutting
down and restarting the computer).
Could anybody else please confirm that it still is an issue that also
happens on their system?
Thanks in advance.

OK, I believe you, just can't reproduce. Which makes it hard to
review/test branches with a fix.
Version 12.10.4 just contained a fix for the SIG code not even being
reached. According to marmuta, we need to additionally use SIGTERM
instead of SIGKILL.
But I can't reproduce... :(

Try clicking more slowly. I just reproduced it by holding the button
down on the return key for a second. I have gnome-terminal auto-starting
in the session and it starts scrolling from all the enter presses right
after activating it.
And yes, without sending SIGTERM Onboard doesn't get the
marmuta, did you experience times when onboard didn't die after a
SIGTERM (and thus the SIGKILL fallback was necessary), or was that just
in case it did happen?

I have been told, that the problem not only is the fact, that unity-greeter
uses SIGKILL instead of SIGTERM; there is also the problem of the code
containing the SIG command is not reached:

I'd like you to test with 12.10.4-0ubuntu1 once it hits the archives. I
think this behavior is better (we kill onboard cleanly on exit now).

The problem is still occurring here with version 12.10.3-0ubuntu2 of

I wanted to also reopen the unity-greeter part of this bug, but I was

You'd need to press enter with Onboard to reproduce this. When enter is
clicked, Onboard fakes pressing enter down, then gets killed before it can send
the key-release. X thinks the key is still pressed down, key repeat sets it and
everything is spammed with n enter presses per second, wreaking
I'm using 12.04 and I either cannot repro this or don't fully understand
what a stuck key would do in Ubuntu.
I typed my password in with onboard, but then hit Enter on the physical
keyboard. I noticed no odd behavior in Unity. What exactly should I be
looking for after login?

I should add that unity-greeter is still using SIGKILL and not SIGTERM.

The fix for Onboard is in trunk and branch 0.97, keys are released on SIGTERM.
I'll link a branch for unit-greeter too. Francesco and me tested both and
couldn't get enter stuck anymore. Robert or Michael, If you get the chance
please check it out.

Thanks for the bug report. What happens is that Onboard is killed right
after sending the key press event and doesn't get to release the enter
key anymore.
What I think needs to be done is to have unity-greeter kill Onboard with
SIGTERM instead of SIGKILL and have onboard react to this by
