Comment # 51 on bug 43829 from n0000b

maybe the same issue? https://bugs.freedesktop.org/show_bug.cgi?id=42960

also, isn't pm-utils somehow deprecated?
if we add the parameter in /etc/pm/config.d/ will the command "systemctl
suspend" be able to turn on the screen? i think that "systemctl suspend"
doesn't rely on pm-utils
