Bug#778362: Periodic (90s) restart of KDM by systemd on jessie

Sat Feb 14 01:22:34 GMT 2015

Package: systemd
Version: 215-10

Platform -- Dell M3800 (XPS-15 alike) laptop, dm-crypt rootfs, jessie
with main/contrib/non-free, nVidia binary drivers (dkms).   *Mostly* a
vanilla Jessie install (dm-crypt'd / is the obvious out of the
ordinary config item).  Note - NOT an upgraded Debian installation -
wheezy (ISO) then dist-upgrade.  One hiccup during dist-upgrade
relating to cryptsetup not being put into initrd - subsequently
resolved.   Jessie linux-image:  Linux shpongle 3.18.0-trunk-amd64 #1
SMP Debian 3.18.3-1~exp1 (2015-01-18) x86_64 GNU/Linux

Problem -- on boot, KDM starts fine.  Whether I log in or not, KDM
restarts precisely every 90 seconds.  (The problem is exacerbated by
my profound lack of systemd-fu.)

journalctl produces notice that kdm.service failed, and restarts it,
but I can't find where to determine why it failed.

Unedited output of   "journalctl -f"  follows here, including
subsequent systemctl (below) period:

shpongle:~# journalctl -f

I've taken systemctl status dumps (below) before and after that one
particular KDM restart.
