Lets take a step back here. I was under the assumption that you were
talking about suspend and resume. Is that not the case? Are you
talking about closing the lid and not suspending? Some oems generate
an acpi lid event when you open/close the lid. Userspace can then do
some action when this event is generated: suspend, blank the display,
etc. While this is less common on modern systems, some oems have bios
code that messed with the display hardware directly to blank/unblank
the displays behind the OS's back. So what exactly are you doing? If
you want to just blank/unblank the display on lid events, you could do
xset dpms force off
xset dpms force on
Normally this is handled automatically by your desktop environment
(gnome, kde, etc.) based on the behavior you've selected for lid
events (usually suspend/resume or blank/unblank).
