Sorry, spam filter hidden your emails. I believe I still see the issue on v4.9-rc1. ... does it still make sense to retry the patch? What I also is re-aranged windows. So I get resume, I get both monitors, but I also see that X windows lost connection with the big monitor (and re-arranged my windows for me). Oh and I guess I should mention: 1) Yes, I only see the issue on the DVI output. VGA seems to work. 2) I do have power switch on the monitors, so it is possible that during resume, monitors have no AC power. (Not merely turned off by the soft switch. No AC power.)
