A big difference today is that the monitor assigned to seat-1 comes back alive BUT it extends the display of session at seat0!
In other words, today, after resume, both monitors provide a big desktop for session @ seat0.
I can't understand how it changed since yesterday. Yesterday the behaviour was as described above: seat-1 card wouldn't come back.
I'm also noticing a changed behaviour after boot and when greeters first appear: until yesterday, they appeared almost at the same time, with mouse pointers exactly in the middle of both. Today, they tend to blink a couple of times, and seat0 mouse pointers appears offset to the right.

In /etc/lightdm/x-1-greeter.log I can see at the end:

[+61,04s] DEBUG: user-list.vala:1030: Adding/updating user hajaszek (....)
[+398,50s] DEBUG: settings-daemon.vala:209: Screensaver activated

Please compare the times. The screensaver activates after about 5 minutes after the greeter is first displayed at system start.
I can't tell at this moment if this corresponds to the time when I suspended/resumed or to the time where screensaver kicked-in on an otherwise unavailable display.

SInce yesterday evening I played with printer drivers from http://www.bchemnet.com/suldr/; I installed/removed some of them back and forth. Then today I did apt-get install apt-show-version, and then did apt-get autoremove as suggested by apt.

I would say this situation is even more annoying compared to the one when seat-1 consistently refuses to show up after resume.
