#240816 — Up-to-date Bullseye, Power Save turned Samsung T55 Monitor off. Couldn't wake it up

[Multipart message — attachments visible in raw view] — view raw

HP Elitedesk 705 G1.  Bullseye XFCE.

I had a timeout set like usual.  Before, I could jiggle the Mouse and press
the Shift Key and it would wake up, but not today.

Fortunately, I was able to power up a Laptop, and SSH into the Elitedesk,
and tell it to Shutdown cleanly.  (But, obviously not everyone has this
option).

(Until I can figure this out, I changed the Power settings to "Never" turn
off the Monitor).

Has anybody else experienced this?

Thanks!

This is the sort of thing which is often caused by a machine
being told to go to sleep -- i.e. suspend to ram, suspend to
disk -- in some way which doesn't let it wake up the video card
again.

A simple DPMS power off / power on ought to work -- from X, try

xset +dpms
xset dpms suspend

and wait a moment. It should come back when you tap a key,
possibly if you wiggle a mouse.

If it doesn't, that's valuable info too.

Look in logs to see if anything interesting happened before you
got to ssh in.

The xset command (version 1.2.4) gave "xset: unknown option suspend".

One note:  Even though I was unable to wake up the Display, I  *was*  able
to ssh in from my Laptop, so the computer itself wasn't "Suspended".
(Also, I never enable "system sleep mode" on a Desktop computer, since I
enjoy listening to Classical Music while the Display may be off.  If I
would be inclined to [i.e. leave my Apartment], I cleanly shutdown the
system).

I am still working to understand these Logs.  I copied /var/log/messages to
my Home Directory and, since it is huge, used the split command.   Nothing
jumped out.

Many thanks!

I had such a problem and solved it by installing firmware for the
graphics card.

I *had* to install some sort of working Firmware before I could even get X
to work.  (I was limited to oversized Text Screens of 80x24, like the old
IBM Monitors from my IBM Mainframe days!)

Installed Firmware:  "firmware-linux-free", "firmware-linux-nonfree",
"firmware-misc-nonfree", "firmware-amd-graphics", and "firmware-realtek".

Thank you.

Thank you all for your responses.  Fortunately, somebody else, I think on
an Ubuntu forum (that I had googled), someone mentioned issues with
light-locker.  And that purging it solved the issue.

So I tried that, with success!

What is the purpose of Light-Locker anyway?

Again, thanks,

Kenneth Parker

To lock your screen and keep it that way until the correct password is 
provided.

This situation occurred again, yesterday and today on my OTHER Desktop
Computer.  It also has the light-locker package installed.  Fortunately, on
this other system, I found a work-around, which was to turn off the
Monitor, leave it off for a while and turn it back on.  So I am still
testing this.  (In other words, I have not purged light-locker yet).

I wonder if light-locker hits the Monitor in a bad way, when putting it in
Sleep Mode?  I'll get the Source Package and examine it, in addition to
conducting further testing.

Best regards,

Kenneth Parker

Just in case any of you are interested in Recreating this, Install
Bullseye, with xfce4 as Window Manager.
Go to Power Settings. /  Display.
For my test, I used 2 minutes on "Blank after", 5 Minutes for "Put to
sleep", and 9 minutes for "Switch off".

Then, I come back in about 15 minutes.  :-)

I get a Flash, with something I might recognize as a Screen.  and then
Screen off.  This is that OTHER Desktop, an HP Pavilion Desktop with an LG
IPS 22MP56 Monitor.

Now, at this point, I *am* going to Purge light-locker on that Machine and
let it go to Power Save again.  I am also pondering the Xorg.0.log to see
if something obvious stands out.

I'll be back.  Thanks as always,

Kenneth Parker

(Sorry, I hit the wrong button last time).

There is a difference in this HP Pavilion.  I only had "Blank After" and
"Switch off" set.   So the two machines weren't the same.  But now, I am
running the Pavilion without Light-Locker installed.

Okay.  This worked.  It also didn't ask for a Password (which is the
*reason* for light-locker).

Now, I am going back to the HP Elitedesk 705 G1.  I changed its "Put to
sleep" to "Never" (which the Pavilion had).  So I want to see if using only
"Blank after" and "Switch off" on the Elitedesk, if it recreates the
situation.  So more testing.

Meanwhile, I also am examining the Source Code for light-locker.

I will return in a few hours.  Once again, thanks!

Hi,

Could this share the same root cause than the following report?

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=991788
"xfce4-settings: black screen after suspend when laptop lid is closed and re-opened"

If so please do not hesitate to share your experience on the BTS :)

Thank you & Best regards,
