Display screen is turned off after timeout even when blanking disabled

dimsuz · 2013-10-10 08:37:31

After a recent update which among other things upgraded gnome to 3.10 my display blanking policy no longer behaves according to a configuration.
Currently it is being turned off (monitor says "no DVI signal" and switches off) after each 10 mins if idle time.

In Gnome's Power Settings I have 'Blank Screen' set to Never.
It used to work perfectly earlier, no blanking, but now it blanks not only when I'm idle, but even when watching some movie in VLC.

I am not sure if this has to do with Gnome update or some other system component is causing this.
Using nvidia driver.

Any hint or link to the topic with the workaround would be greatly appreciated.
I tried google and local forum search and found nothing on the topic

I experience the same with the latest update to Gnome 3.10. I don't think it is graphic card specific since I am using an Intel integrated card.

Yet I have not found a solution either.

Hm. So this might be a gnome bug after all.
Will search their bugtracker, but still I think I'd check in other WM's or DE's to be sure it's gnome's and then - report it

Also have this problem after the upgrade.

You could try some changes to /etc/systemd/logind.conf as mentioned on the XFCE wiki page

This looks more like something to do with button/lid function assignment, while we here have some kind of screen blanking or DPMS timeout management issue...

I got the same problem on my other pc, Arch with XFCE. Although the powermanager was set to not blank the screen or to hibernate.
Found this, made the changes, no problems anymore.

Don't see Key in HandleSuspendKey or HandleHibernateKey as another word for button.

Hello,
Same problem for me with Gnome 3.10, didn't happen before...

Edit : I saw this topic : http://wyldeplayground.net/display-scre … -disabled/
He has a Nvidia graphic card, me too (GTX660). Do you have a Nvidia card too ?

Same problem here after upgrade to 3.10, also AMD card here with AMD prop. drivers, so it isn't a card specific bug but rather a gnome bug, not even the caffeine extension works, it's fairly annoying.

jrussell · 2013-10-11 06:41:10

I think you have to be using gdm for those gnome settings to have effect.

dimsuz · 2013-10-11 08:21:28

Ha, Anthony25 that link actually shows a copy of a top post in this topic

So to answer you: yeah, I have nvidia card.

jrussel, yes using gdm.
How about others with this bug, gdm too?

Anthony25 · 2013-10-11 10:41:39

Yep, GDM

Edit : Dimsuz, I'm so an idiot, didn't saw it was you who wrote the topic ...

Heh, there are so much copy-n-paste websites nowadays - no wonder!

orschiro · 2013-10-11 11:14:15

I am not sure if it is GDM only related. I do not use GDM and have the same problem.

jrussell · 2013-10-11 12:10:05

Sorry I should clarify, I'm saying that I think that those gnome power/lock/suspend only work if you are using gdm as your display manager.

ie: GDM makes those power/lock/suspend work.

So I see you are using GDM so there is possibly a bug here then

orschiro · 2013-10-13 06:46:55

I just noticed that this is not Gnome only. Also in Cinnamon 2.0 I disabled all power savings through `xset s off -dpms`. But still my screen turns off.

Oh, valueable information.
So far I had no time to check in some other environment.

Maybe an Xorg issue then. Or video driver's.

orchiro which video driver do you use?

xorg-server 1.14.3-2
xf86-video-intel 2.21.15-1

bmanuel · 2013-10-13 11:02:27

I've the same problem and the only solution to VLC is to use UMplayer, this will inhibit the screensaver properly at least..

dimsuz · 2013-10-13 11:28:01

I tried to search freedesktop's bugzilla but didn't find any bug which looked similar. Maybe used the wrong keywords...

evaliauka · 2013-10-13 17:03:38

Seems like fix will come soon

staffe85 · 2013-10-13 17:13:55

I don't think this is an xorg or driver related issue. I tried AMDs catalyst drivers with xorg 1.13 and the open source radeon drivers with xorg 1.14. My screen turns off after a view minutes with both configurations. All has been fine before Gnome 3.10. So if it's not the desktop environment, nor the xorg-version, nor the graphic drivers, maybe it's the display-manager? Could it be, you all use gnomes display manager GDM?

dimsuz · 2013-10-13 17:37:11

evaliauka, wow thanks! Nice to know!

Anthony25 · 2013-10-13 23:34:12

Actually the fix is already here, and works well : https://bug709114.bugzilla-attachments. … ?id=256549
You just have to patch the gnome-settings-daemon sources with this patch.

Like Bastien Nocera (a gnome-settings-daemon developper) says in the gnome bugreport, it's because the X server now sets a default value for the DPMS timeout (set at 10mn), even if there is already something which manages it (gnome-settings-daemon in our case).

I just noticed myself this annoying issue and I do not use Gnome nor GDM.

The thing is after checking the xset settings with

xset q

I noticed that the DPMS settings for Standby, Suspend and Off were back to their default values (60/60/600) instead of the 0/0/0 as I am using

xset s off &

in my openbox autostart file to avoid the screen blanking.

The way I fixed it was to simply run

xset -dpms

being the DPMS featured as disabled when queried.

Afterwards I checked that the screen did not blank again and 1) logged out and 2) restarted checking both times that the DPMS were the ones expected (0/0/0).

Thus, so far, I have no issues with the screen blanking in a non Gnome environment (Openbox) anymore.
