--- Comment #52 from klausenbusk@hotmail.com --- (In reply to comment #51)

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

I looked in the pm-utils sourcecode, and adding acpi_sleep=s3_bios to the cmdline fix it for me.
