I attempted to build and install debian packages for updated lightdm + lightdm-gtk-greeter 1.1.4 yesterday, which went fine; I'm expert enough APT user and prefer installing software as packages.
I found that plain old /bin/login also stopped updating /run/utmp /var/log/btmp and, or /var/log/wtmp; the /run is tmpfs mount on Debian these days and /var/run is a symlink to /run IMHO, something is or may wrong with pam files on Debian; hence w and who report nothing under X and, or over tty terminals. I have: [bsd@mon ~]$ uapt version lightdm 1.1.4-1 [bsd@mon ~]$ uapt version lightdm-gtk-greeter 1.1.4-1 [bsd@mon ~]$ lsb_release -a No LSB modules are available.
