With Ubuntu switching to GNOME, looks like Unity folks don't care about
this anymore.

This and the fractional scaling issue were the only 2 issues
that kept me from using anything higher than 16.10 until now,
and I've decided to take the matter into my own hands.

I've bisected the recent commit logs and found 2 possible faulty commits.
Reverting those fixed the fractional scaling issue,
and I'm pretty sure it fixes the reset bug.
(The commit almost directly tells itself.)

I'm still using 16.10 and tested those new Unity builds within a VM,
so I can't test whether it fixes the reset bug myself.
I'm preparing those PPAs to get ready for 18.04 LTS.
(As I prefer Unity over GNOME.)

I've added build for Xenial(16.04) as well.

Please test it and let me know how it goes!

  UI scale being reset to 1 everytime when display sleeps for a while

Bug description:
  After upgrading to Ubuntu 17.04,
  the HiDPI setting(Scale for menu and title bars)
  is being reset to 1 everytime when display sleeps for a while,
  making everything looks small.

  If the display sleeps and I resume it instantly, it's fine,
  but if the display slept for long, the HiDPI setting gets reset to 1.

  My guess is that if a display is plugged in(detected), the old DPI
  setting is not restored.

  This issue is not present on previous Ubuntu versions
  and the same issue persists even after a fresh install.

  *---------------------------------*
  This bug is now present also in 16.04 since a recent update, experiencing 
this in Xenial since 23 Feb 2018 at least. We could trace the cause of the bug 
in the recent backports/bugfix updates to Xenial.
