Greetings,
I have an ongoing issue with hibernate/suspend and dual monitor setup.
Hibernate works great! Suspend works great! Dual monitors work great!
Xscreensaver works great! I do not lock my session. I do not have systemD (I do have elogind/libpam).
The problem: When I launch Xscreensaver, it works great, when it calls for the system to suspend, it will blank one monitor, and then someone, somehwere, disables the output of the displayport, effectively turning off the second monitor. The first monitor stays powered on and blanked. Then, because the displayport is disabled, the system/Xscreensavers thinks there is no monitor attached and changes the layout to single monitor setup.
On resume the second monitor wakes, and the system thinks there is yet another setup and mirrors the display output onto the second monitor - yet when I go and manually change it back to the proper layout, all of the open programs on that screen are still there and the wallpaper is restored - like it never happened.
I checked with Xscreensaver and he tested his systems and confirmed this behavior is not an Xscreensaver bug.
Here is the log output from Xscreensaver:

I just want a whimsical screensaver to make me smile, and my computer to hibernate and not change my display layout. Any thoughts?
