What do you mean with that, i. e. where did you see the lid switch
status? From "upower --dump"?

For downgrading you can select your architecture (i386 or amd64) from
https://launchpad.net/ubuntu/+source/systemd/198-0ubuntu11.1, then
download the older .debs, and install them with "sudo dpkg -i
<package>.deb". It's a bit unlikely that systemd-services would affect
upower's ability to read the lid switch status, especially as the diff
(http://launchpadlibrarian.net/150608501/systemd_198-0ubuntu11.1_198-0ubuntu11.2.diff.gz)
does not affect anything is related to lid switch (only timedated,
localed, and hostnamed).

But it can certainly not hurt to try and downgrade and see which
particular package caused this. I suggest starting with systemd-services
and udev first and keep the libraries. Sometimes a mere package upgrade
causes the weirdest things which are completely unrelated to the actual
code changes.

Title:
  Can the update of libudev from 11.1 to 11.2 caused problem with lid
  switch?

Status in “systemd” package in Ubuntu:
  Incomplete

Bug description:
  After an update of libudev/systemd (details on update below), Ubuntu
  was not able to read the lid state anymore. Now, the lid state always
  reports "open".  Before the update on the 18th of September, the lid
  switch worked perfectly and put the system in suspend. Now, it is not
  working anymore.

  Therefore my question: Is it possible that the update of
  libudev/systemd from 11.1 to 11.2 caused the problem? How could I
  downgrade from libudev/systemd 11.2 to 11.1 to try out whether it
  works (synaptic offers only v11 and gives lots of dependency issues)?
