DPMS and Panasonic Plasma Screen

Hi All,

Trying to get my PC to put my Panasonic 50" Plasma in suspend mode with DPMS commands using xset. (Over HDMI interface ..)

When I execute the command "xset dpms force off/suspend/standby" the panel goes to a semi dark state with the input source name showing, but does not suspend.

I have trawled through all the TV's power saving modes, trying all sorts of combinations, but nothing ..

Any help much appreciated ..

What graphics card, what drivers? People on forum are not mind-readers

Re: DPMS and Panasonic Plasma Screen

Allrighty then, so you've of course read DPMS and Nvidia wiki pages and you have tweaked your xorg.conf with this:

Option "DPMS" "true"

?

Yes, to both ... I could not find the answers there, or a search on the forums .... hence the question my friend.

EDIT: Looking further into this, I found this in the xorg log file ..

 (WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)

and further down ...

[241879.915] (II) NVIDIA(0): ACPI: failed to connect to the ACPI event daemon; the daemon
[241879.915] (II) NVIDIA(0):     may not be running or the "AcpidSocketPath" X
[241879.915] (II) NVIDIA(0):     configuration option may not be set correctly.  When the
[241879.915] (II) NVIDIA(0):     ACPI event daemon is available, the NVIDIA X driver will

[241879.915] (II) NVIDIA(0):     "AcpidSocketPath" X configuration options in Appendix B: X

I wonder if this is an issue?

Re: DPMS and Panasonic Plasma Screen

Do you have acpid and acpi installed? It seems acpi is, but cant connect the daemon (acpid). I would look into that.

Re: DPMS and Panasonic Plasma Screen

Hi There,

No. neither of those packages are installed .... but I am not sure why I need them.

With my old plasma screen the xset command worked fine at turning the screen off .. there are only two things that have changed:

1. A new plasma
2. A system upgrade ..

So unless the upgrade has required the acpi packages now ... I am still not sure why they are needed, they are normally used to put the computer in suspend, not use DPMS
on the display ..

Cheers,
B

Re: DPMS and Panasonic Plasma Screen

They may not be needed but the error is complaining about them not being there. I know for my nvidia drivers I have always used them, also the new nvidia drivers released have some changes that have effected some cards. Maybe look into those to see if any pertain to your issue.

I would just try installing them and see if it solves the problem, would be a very quick thing to test and if it does not work, remove the packages.

edit:
I just thought of this, do you have a monitor configuration file setup in /etc/X11/xorg.conf.d/ ?
If you do is DPMS put in there if not you could try making one with
Option "DPMS"
in it. Could be worth a shot if you do not want to try installing ACPI. Not sure if this will solve/help but I remember I use to put that option when I used Xorg conf files

Try reading further up the thread, it's in there already ;-)

I will install them .. but not hopeful it will change anything ..

Re: DPMS and Panasonic Plasma Screen

Yes I noticed you did it for you nvidia conf. But I am talking about setting up a monitor conf file for your TV
From the wiki:

Setting up DPMS in X
Note: As of Xorg 1.8 DPMS is auto detected and enabled if ACPI is also enabled at kernel runtime.

Add the following to your /etc/X11/xorg.conf in the Monitor section:

Option "DPMS" "true"

So instead of an xorg.conf setup a **-monitor-TV.conf file for the plasma. This will make you have conf files for each monitor in the location I stated above and also a 20-nvidia.conf

As you see it states in the monitor section, so you need it for both monitor and nvidia. At least that is how I read it and have it setup on mine and can turn off my 60" flat screen with DPMS. But I also have acpi setup since it is something DPMS seems to require according to the couple wiki pages I can find.

Re: DPMS and Panasonic Plasma Screen

Hi vwyodajl,

It makes no difference weather you have a monitor section in the xorg.conf file or a separate monitor.conf file, xorg supports both.
And having <Option "DPMS" "true"> or <Option "DPMS" "1"> or <Option "DPMS"> are all the same meaning ..

I will try the acpi stuff when I get home tonight ... still don't understand then why I did not need it for my other Plasma, it reacted to "xset dpms force off" just fine ..

Cheers

Re: DPMS and Panasonic Plasma Screen

I get all that stuff. I guess I am not explaining myself well here. You need DPMS settings in both the "Monitor" and "Device" sections. Either in a xorg.conf or if you ditched that like most have now, set up the appropriate **-monitor/device.conf files in xorg.conf.d. One for each monitor (TV's and normal screens) and one for the device you're using, with DPMS enabled on each one.

The reason the other could have worked is nothing more than luck, as with the recent nvidia update's vesa broke for many cards and nvidia states they do not even understand how or why it even broke. Also they stated it was just luck it has always worked until now.

For my personal setup to work with my flat screen, I had to have DPMS in both sections, removing it from one or the other makes DPMS not work for my setup. I always run my system with acpi/acpid so I have a feeling installing and setting them up will help.

Hope that helps and good luck tonight.
