I found a way to bring a display back to life if it's off but available from xrandr output. You need to say something like
Code:
xrandr --output DVI-I-2-2 --auto
It works, but unfortunately I have to rearrange displays after that. Something like
Code:
xrandr --output DVI-I-2-2 --right-of eDP1
xrandr --output DVI-I-1-1 --right-of DVI-I-2-2
