I've just had a different idea (that I should've had earlier).

You can enable the backports repository. I've just checked:

# cat /etc/apt/sources.list
#deb http://uk.archive.ubuntu.com/ubuntu/ utopic main restricted
universe multiverse
deb http://uk.archive.ubuntu.com/ubuntu/ trusty-backports main

# apt-cache policy lightdm
lightdm:
  Installed: 1.11.4-0ubuntu1
  Candidate: 1.11.4-0ubuntu1
  Version table:
 *** 1.11.4-0ubuntu1 0
        100 /var/lib/dpkg/status

So it's available in -backports and is at the same version as my 14.10 version.

And its "Release" file has "NotAutomatic: yes" and
"ButAutomaticUpgrades: yes" so you won't be pulling in anything from
there unless you install it specifically; it's more or less similar to
having "enabled=0" in the repo file of "backports" on RHEL/Fedora and
installing a package with "yum install --disablerepo=*
--enablerepo=backports lightdm".
