Forwarded from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=781949 :
lxdm restarts every 2 minutes if system loaded with default initialization system (systemd). I can log in and work, but when 2 minutes will be expired, lxdm will be restarted.
If init systemd is sysvinit, lxdm starts normally.

I'm using lxdm with systemd everyday on fedora.
It's not bug of lxdm, the packager likely provide a bad lxdm.service, try remove the last line of that
