Screen goes black after 15' on VLC 1.1

[TeM]

Hi everyone,

I'm experiencing a really annoying issue with VLC 1.1.

I'm using archlinux with the last Gnome and VLC packages and while playing a movie full-screen, the screen goes black after like 15-20 minutes, as if it was going into sleep mode except I made sure that :
* I have disabled power management (tested this both using the gnome configuration menu and the inhibit applet)
* This is a bit weird because it feels like it's not power saving, I'm much pretty convinced that the led of my screen is supposed to turn orange when it switches to PS mode. however it stays blue when this happens, meaning this is only the signal going black, not the computer switching to PS.
* gnome-screensaver is NOT installed on my computer
* Moving the mouse or hitting a key brings the image back
* Sound is still playing while this happens

Downgrading VLC to version 1.0.6 solved the issue.

So it seems like a VLC regression to me. However from what I can read, I seem to be the only one experiencing this issue.

Anyone got any clues / suggestions / solution / question ?

DPMS?

DPMS?

here's what i have during playback (xset q)
DPMS (Energy Star):
Standby: 0 Suspend: 0 Off: 0
DPMS is Disabled

No matter what you have to say, that is definitely a screensaver or power management feature of your system.

Well,

I'm sorry but :
* The monitor is not going into "sleep mode" i've just double checked, it is really the image which is turning black
* I'm running arch, and due to the way this distribution installs, I know pretty much what's running on my computer, and I'm rather affirmative that :
--- I have no "screensaver" packet installed
--- DPMS is disabled when vlc is running
--- I've turned off any possible Power Management feature I could think of

Moreover, as I already highlighted it :
* I can't reproduce the issue in vlc 1.0.6, Downgrading to this version solves the issue.
* I had never experienced this issue with any other build of VLC in like, 2 years
* Other players such as MPlayer are working well

So no matter what you have to say, this looks like hell there is some VLC-related issue here !

And VLC versions 1.0.6 & 1.1.0 use different interfaces to inhibit the screensaver... so there you have it, screensaver problem.

hello

I've been experiencing the same problem.
the power management kicks in after a while.
it doesn't matter if I set
inhibit=1
in the config file to inhibit the power management daemon

Hello,

I am running this on opensuse 11.2 32 bit.
I have also tried the downgrade trick and there the powermanagement does not kick in.

so this happens not only on arch but also on opensuse.

When you say
"And VLC versions 1.0.6 & 1.1.0 use different interfaces to inhibit the screensaver... so there you have it, screensaver problem."

I read it like this.
platform + screensaver + software v1.0.4 (old interface) = function properly
platform + screensaver + software v1.1 (new interface) = malfunction

I tested this, the only piece of the puzzle that changes is the vlc player version.
Why do you blame the screensaver ?

It looks like the problem was related to the "blank time" xorg option.

Modifying the xorg.conf file such that the Serverflags section looks like :

Code: Select all

Section "ServerFlags" Option "blank time" "0" Option "standby time" "0" Option "suspend time" "0" Option "off time" "0" EndSection

Seem to solve the issue.

I still blame VLC for this because it does not properly inhibit the X screen blanking.
Don't really care if it's because of the "new interface" or not : the thing is : it does not work, period.

Does that solve your problem?

Gimme some time to figure out how to find the patch and apply it.

[TeM]

Sorry, I was away for a while.

I'll be able to give this a try next week, I'll keep you posted.

PCLinuxOS 2010 similar issues as OP
Just after upgrade from 1.06 to 1.1.1 the screensaver will come on when watching a movie. I tried reset the vlc preferences, no luck.

[snatch213]

Hello,

Sorry for the delay, but life got in the way.

I've tried your patch remi and it works.
I'm now watching a dvd with the screen saver settings in kde set to 1 minute and the screen does not blanc.

Good one

I have this same problem, and would like to try remi's solution, but I haven't any idea what to do with that code! I'm sort of a linux newbie, so I'm not sure where that code should go, or what type of file it should be saved as.
My guess would be in the vlc install directory saved as a bash file, but I'm not sure. Thanks!
