systemctl stop sddm doesn't (always) kill sddm-greeter

[github-cygwin]

Hi,

while testing my local sddm theme as in issue #335, I noticed that

init 3

or

systemctl stop display-manager

or

systemctl stop sddm

more often than not fails to kill the child sddm-greeter. If you do this a few times during update,
maintainance, or testing, the machine ends up collecting disfunctional sddm-greeter processes.

This is on Fedora 21 with systemd-216-12 only running a local X session on display :0. I checked
the sddm.service file and the Fedora file is created from the upstream sddm.service.in with just
@CMAKE_INSTALL_FULL_BINDIR@ set to /usr/bin.

I may be wrong, but AFAICS stopping the sddm process should always stop sddm-greeters as well.
Or am I missing something?

Thanks,
Corinna

I've never seen this.

I can reproduce it basically at will on my Fedora 21:

Can you paste the output of journalctl -u sddm?

Nothing of interest in there, unfortunately:

$ sudo journalctl -b -u sddm
-- Logs begin at Sun 2013-12-22 13:43:49 CET, end at Sat 2015-02-21 17:56:17 CET. --

Feb 21 11:03:00 foo.example.com sddm-helper[1904]: pam_unix(sddm-greeter:session): session opened for user sddm by (uid=0)

10:45 and 10:47 correspond with the timestamps in the ps output I pasted
into my previous reply. 11:03 corresponds with me starting sddm again
after creating the output for you. Nothing else from sddm is in the
logs from earlier startups, just what you see above for today.

Sorry,
Corinna

Closing this by lack of information and reproducibility.
