X.org 7.1 DPMS (display power management)

I just upgraded to X.org 7.1 (from 7.0), and now my monitor won't go into standby/suspend/off anymore. It is enabled properly:

Same problem here.

Strangely enough, after this bug report, it did go into standby. It seems as though it does work once you've run "xset dpms force suspend" (or another power mode). Can you confirm this, zxiiro?

I can't repeat the workaround either (it wasn't a solution to begin with).

I had this problem with nvidia-drivers 8774 and xorg 7.1 about a month back. However, I downgraded xorg to 7.0 since then, and I do not face such problems anymore.
But I do remember that DPMS would not work, and moreover the CTRL+ALT+<KP +>/<KP -> which are used to rotate through the different resolutions present in xorg.conf did not work. Could you confirm if the above keybindings still work in xorg 7.1? If not, it is either a bug in Xorg or in nvidia-drivers (assuming you are using nvidia drivers too).

I have nvidia-drivers 1.0.8774, and I also had them with Xorg 7.0. In 7.0, I didn't have this DPMS issue. It came when I upgraded X.org.

Also, not really relevant to the subject, but my CTRL-ALT+/- keys work fine.

I can confirm this problem too... although with a twist. with a freshly (re)started Xorg, DPMS is working fine for me, but as soon as I watch some live tv in MythTV and exits, DPMS is not working until I either restart Xorg, or change some DPMS settings or use the force command. After that DPMS is working again.

MythTV is supposed to deactivate DPMS when watching tv, and reactivate it when not. Here's another user that have exactly this problem:

I have upgraded to nvidia-1.0.9626 with xorg-7.0 here. DPMS and the CTRL+ALT+<KP_+/-> work fine. I haven't dared to upgrade to 7.1 (why break a working system

).

I've had my problem under observation for a while now, and it seems to be the opposite of what Miwer states. My DPMS works fine when X is freshly started, but when I have open mplayer or something else that deactivates DPMS, it won't go into standby/suspend/off again. But, I'm not completely sure of this, it could also be random... Problem is not solved yet, anyway.

I recently upgraded to nvidia-drivers 1.0.8776 BTW, but that didn't help. Didn't expect it to, because the problem seems to be X.org.

I had the same symptom after upgrading to xorg-x11 7.1

Mplayer (the normal one) did exactly the same, not restoring the screensaver status when you press the close button, giving a broken pipe error, if I remember correctly. That's why I wrote a wrapper script which would save current DPMS status, start mplayer, and restore DPMS setting. Good to know they fixed that bug, because now I don't need that script anymore. It's also strange that they fixed it, because a bug report I filed once, was dismissed as invalid, and the window managers were blaimed for the fault.

But this is not the problem I'm experiencing now. As stated, even when "xset q" reports DPMS to be active, it won't engage. At least, sometimes it does, and sometimes it won't.

Hi all,

Because my work day today is totally unproductive, I thought I'd chime in with a "me too" message. I've noticed of late the same problems with similar symptoms. Interestingly, I had this problem way back when I was running XFree. The problem then was mplayer, which, for some reason, didn't reactivate dpms and given these posts it seems as if the same thing is happening again. I am not sure whether xine does the same thing.

I've also still got this fullscreen playback issue, which I posted about elsewhere.

Hoping somebody figures this out. Has anybody posted this to a bug tracker?

Best,

Alex

Hi,
I updated xorg and nvidia-drivers today. Everything seems to be working fine (DPMS is working and CTRL+ALT+<KP_+/-> is working)

FYI:

Hi,

Same problem here. xset q reports DPMS is enabled. When I first boot the system, my monitor does go off, but if I work normally with my computer, after a period of time it stops working. I don't know if it's because I launch mplayer or not (it may be), the fact is that it stops working, I don't have time to make extensive tests to see what is the real trigger...

I am running AMD64-stable so this includes Xorg 7.1 and drivers from Nvidia (I have a GeForce 7600).

Should we file a bug report, and where?

Emerging x11-drivers/nvidia-drivers-1.0.9629 (which are in ~ for amd64 and x86) solved the DPMS issue for me. I've been testing that for 3 or 4 days and everything works as it did before.

Before trying with lastest drivers in ~amd64 I tried with x11-drivers/nvidia-drivers-1.0.8774, which kept the same behaviour with DPMS.

You should give x11-drivers/nvidia-drivers-1.0.9629 a try.

I don't know if this is related. But xorg will go to a blank screen aand after about 10seconds my monitor will flash "No Signal" and try to go into power save mode but as soon as it does xorg trips it back to a blank screen and the cycle continues.

Hi all,

I have the exact same problem here. Glad I find this post proves I am not so unlucky, the problem has already puzzled me for a while. Upgrading the nv driver is not an option for me as my laptop use an ati x300. I am using ati proprietary driver, hopefully a fix will come up soon.

I find it kind of strange that this problem occurs with ATi and NVidia hardware, and can be fixed by upgrading the drivers in case of NVidia. It may work, I just think it's strange...

Hi,
I too have the same problem with a nvidia driver on a toshiba satellite laptop. This appears to be a known issue with Xorg 7.1 and probably will be fixed in 7.2. Have you people seen the following bug report?

I'm not sure ACPI events are my problem, because when I force a DPMS mode, it stays there. It just doesn't want to time out into a DPMS mode. But, we'll see. I would seem that waiting for the appropriate upgrade is all I can do. I hope Nvidia 9629 becomes stable soon. I'd like to exerpiment with composite rendering.
