[Solved] Monitor doesn't sleep

Good Evening!  I've been reading every post about screensavers, monitors, and power management that I can.  I'm using the base install, so I should be using the XFCE Power Manager with light-locker.  The problem I have is that the monitor does not go to sleep.  After a period of no activity, the screen will blank but does not sleep.  My monitor will go to sleep in windows, but not on bunsenlabs.  I notice the same behavior on a second computer and on my laptop.  Any ideas about how to get my monitor to go to sleep?  Thanks...

Re: [Solved] Monitor doesn't sleep

Does this work:

xset dpms force off

Can we please see the full output of:

xset -q

Finally, has your monitor ever entered sleep mode with any other GNU/Linux distributions?

Re: [Solved] Monitor doesn't sleep

 xset dpms force off 

This doesn't turn off the monitor or put it to sleep.  It actually freezes the screen (the cursor disappears) and the monitor will stay like that until I move the mouse or press a key.  The same thing happens when I altered the light-locker.desktop file to keep the login screen from appearing.

 xset -q 

Here's the output:

Keyboard Control:

DPMS (Energy Star):

I set the screen blanking very short because I've been trying to fix this problem.  The monitor was hooked up to another computer and would sleep just fine.  It worked with #!, xubuntu, and fedora.  It is now connected to a new computer with a fresh install of bunsenlabs.  I should have two live distos that I'll try on this new computer.

OK, what is your graphics hardware?

lspci -knn | grep -iA2 '\''[030[02]\]'

Re: [Solved] Monitor doesn't sleep

nick@dell-bunsenlabs:~$ lspci -knn | grep -iA2 '\''[030[02]\]'
00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:5912] (rev 04)
	Subsystem: Dell Device [1028:0763]
00:14.0 USB controller [0c03]: Intel Corporation Device [8086:a12f] (rev 31)

The bunsenlabs live distro behaves the same way when I issue:

xset dpms force off

But, my laptop monitor sleeps with this command.  So, it's just this one computer and monitor.

Re: [Solved] Monitor doesn't sleep

^ You have no kernel drivers loaded for your video card.

I think that's Kaby Lake so you could try this guide:

Debian stretch offers better support but we only have an experimental (development) version of BunsenLabs based on that:

This worked.  The monitor sleeps as expected.  Didn't really consider the video drivers.  Thanks...
