I followed your advice and multiseat setup still works. And still seat-1 resume problem remains.
I noticed that if I do (as root) a number of commands like:
# DISPLAY=:1 XAUTHORITY=/var/run/lightdm/root/:1 xrandr --output DVI-I-2 --off # DISPLAY=:1 XAUTHORITY=/var/run/lightdm/root/:1 xrandr --output DVI-I-2 --auto
Then seat-1 comes back after suspend.
