Bug Description

http://i42.tinypic.com/izvrb7.jpg

However, that did not change the fact that after 10 minutes, my monitor goes off.

And what makes this really odd, my monitor goes off even while I watch something on VLC or YouTube. So, I have to keep moving the mouse every now and then.

XScreensaver has been removed from Lubuntu 13.10 (Saucy) so I can't understand what is going on?

I have to do the same thing when I'm in the classroom and we're watching a long music performance on MPlayer. I have to remember to keep moving the mouse every few minutes to restart the clock before the presentation screen and netbook monitor goes blank. No settings in Power Manager seem to make a difference. This also happens on liveCD disks ... if I don't touch a keyboard or mouse for 10 minutes, the screen of my netbook or my Mac Mini (or any computer I'm installing Lubuntu on) will go blank.

Correction:

The command: xset s off

Has helped to stop that issue - thanks a lot.

I'm sorry, I thought that was the same previous command suggested in comment #3 - https://bugs.launchpad.net/ubuntu/+source/xfce4-power-manager/+bug/1193716/comments/3

but I was too rushy, I guess.

So far, so good. However, I did not rebooted yet. Not sure if everything will be ok after the reboot or I have to re-issue the same command again? when I will reboot, I will get the answer :)

Now, let's wait until this bug will be fixed :D

You are right. For now, as a workaround for this very annoying bug, installing XScreensaver will do the needful as explained on: https://bugs.launchpad.net/ubuntu/+source/xfce4-power-manager/+bug/1193716/comments/15

But, as you all may know, 'xscreensaver' is not installed by default with Lubuntu 13.10 :)

xfce4-power-manager is installed by default in Lubuntu.
Nevertheless the two configuration folders for the startup applications have been disabled in Lubuntu 13.10 and newer versions according to e-mail posting by @Julien Lavergne [1]

So, try to startup properly the xfce4-power-manager by adding an entry in
 ~/.config/lxsession/Lubuntu/autostart file
or graphically :
Start Menu - Preferences - Default applications of LXSession - Autostart .

The command should be simple like

/usr/bin/xfce4-power-manager

Then please test again if Lubuntu "respect" your settings. If yes, then we can mark this bug as invalid because it is Lubuntu specific and has nothing to do with xfce4-power-manager.

@amjjawad

you filled a bug against a project. (xfce4-power-manager).

The xcfe4-power-manager works without problems in my Lubuntu installation. The fact the Lubuntu decided to drop those two "startup applications" folders has nothing to do with the xfce4-power-manager.

Based on that, I wanted more info (the test case on comment #21) so I marked the bug incomplete , meaning.. "wants more info".
You provided the info, and marked the bug again as confirmed. That's OK. It's a logical procedure.

Now developers need to take action and find out if this bug is for real or a "false alarm".

Don't take my actions as an opinion or something. I'm just following the procedure.

I added the upstream bug here.
It would be good for the life-cycle of this bug if you login there (upstream) and add a comment - Url link - to this existing bug.

Eventually, after a new installation of Lubuntu I checked this bug as "Yes, it affects me" (again) . The problem seems to involve the xfce4-power-manager and even if you autostart it properly , the settings will not be respected.

xset will overwrite the settings.

Despite lubuntu 13.10 has xscreensaver not installed by default, my monitor blacks out after 10 minutes no matter the settings in xfce4-power-manager.
Even when a (music) video is desplayed, the monitor switches off and music freezes to a consistent beep sound.

this makes playing an mp3 playlist or internet radio a nuisance than a pleasure.

For those who are suffering for this 10min problem:
Please run this on command line:

Does it say that timeout is 600 (or non-zero anyway)?
If that is the case, does it help, if you run the following command?

xset s off

If that helped, does the timeout 600 come back after reboot?

In , Jarno Suni (jarnos) wrote :

I tested it myself, and yes, timeout 600 comes back when you log in again (on Xubuntu 13.10). A workaround is to add command "xset s off" as an autostarted application in session settings (provided that resetting to 600 does not happen automatically within session.)

I think PM should override xset setting at least, if you choose Mode > Presentation.

Revision history for this message
In , Jarno Suni (jarnos) wrote :

And by overriding I mean that Xfce4 Power Manager should do "xset s off" when it enters Presentation mode, and restore to previous screensaver setting, when changing back to Normal mode.

I think it is not desirable to disable X screensaver by Xfce4 Power Manager in Normal mode, since user may want to have some screensaver activated, instead of just blanking the screen, according to that timeout setting. Monitor power management will work regardless according to DPMS settings (that Xfce4 Power Manager sets), if control stays in the same virtual terminal.

Here is some information about X11 Screen Saver Extension:

Revision history for this message
In , Jarno Suni (jarnos) wrote :

As for the Presentation made, when it is used, and user locks screen, xflock4 may change DPMS on, so after unlocking, the mode may not work, unless re-enabled. It would be nice, if xfce4-power-manager could re-enable Presentation Mode (like "xset -dpms ; xset s off" in shell) automatically after screen locking stops, but this may be impossible at least with current xflock4, because normally screen is still locked after xflock4 exits.

Jarno Suni (jarnos) wrote :

I wonder, if the power manager could override the screen saver timeout. It could change the X setting, but I think it is better to change the setting by "xset s off" during session startup (i.e. as part of autostarted applications).
I still wonder where and why is that default 600 sec timeout set?

The default value is 10 mins, so you might have to change that in the settings dialog of xfce4-power-manager to get a different value.

You can always control whether the values in the power manager are applied correctly by running "xset q | grep timeout" in the terminal. (Note that the values by xset are seconds while the power manager converts that to minutes, for convenience).

Right, this means that the X server is not responsible for your screen going blank, hence xfpm can do nothing about it. Are you maybe using XScreenSaver? If so, that app uses separate settings that cannot be modified by xfpm.

no, I did not tamper with the disk. The way the pc wakes up is by pressing the keyboard. Two of my computers experienced the problem but in a different way. I installed lubuntu 13.10 in 2013 at two machines at the same period of time. The desktop experienced both screen blacking out and disk inactivity, while the laptop only screen blacking out.

Today the laptop's problem is solved (kubuntu 14.04 installed), but the desktop's problem remains even after 14.04 upgrade. Haven't installed kubuntu to it as it is a weak machine.

Also I forgot to mention that the pc does not power-off, it shuts down and I have to press the botton on the box to power it off.

I went in to both Power Management and Light Locker and set both values to 0, and turned DPMS control off by unclicking the DPMS checkbox. I thought it was weird that I went from display and system going off after 10 min to this odd behavior of screen would blank, BUT I could tell it was only a fullscreen black graphic as the contrast and brightness were still in play AND I could continue to hear the audio of my full screen based flash player [I use Plex Media Server (god I love it)] continuing without any interruption. I thought it had to be something more. After looking around the web a little I rememebered XWindows does have it's own seperate control for the display. I then went ahead and issued the

xset s off

(basically x stop trying to call screensaver ever (which there is none installed). Once I did that t sppear to be fixed I have been running with no screen blanking for awhile now.

Maybe it would be as easy as an eval if switch off display is set to 0 then run xset s off to cover the Xwindows portion of screen control. I have even been able to set DPMS back to on and have continued to enjoy no blanking or display powering down.

Amazing bug, so simple and I am still applying workarounds (xset in .xinitrc) 3 years after...

@Mike Miller: Obviously you're not using the latest Xubuntu release, because in 14.10 (released in October) light-locker-settings doesn't handle blanking anymore if xfce4-power-manager is installed.

@gatopeich: As I just mentioned, this bug was fixed only in xfce4-power-manager 1.4, which was released in Xubuntu 14.10.

Bug policy: If I understand this correctly, because someone THOUGHT a bug was fixed in the newer version - which is NOT LTS - you feel everyone else should suffer until the new LTS come along.

This is doing everyone, and all Linux, a great disservice.

I do NOT install a new system to 'test' if a bug is fixed.

I have tried to simply use Synaptic to remove light locker, and it wants to remove Lubuntu desktop also.

On two different systems.

I have no problem attacking the issues by hand. But policies like this mean my sons cannot recommend Linux to an average user. Both work in the computer industry and take care of their friends and family.

Three YEARS!!!

Just like the Gnome power off button. Who are you developers trying to help?
Each time someone quotes a bug policy, someone else decides they don't need Linux.

Yes, this is a flame.

I'm on Xubuntu 14.04 LTS and this bug still affects me. Though it seems like the fact that it's still broken is known and will not be fixed?

This is pretty embarrassing, guys... it's 2015 now. The most basic functionality of one of the most basic features of my operationg system does not work at all. The solution is to upgrade my OS? Or pop open my terminal? For a bug that was filed YEARS ago?

That screensaver timeout should: A) be turned off, or B) have some interface to change it besides "xset".

Gah, sorry to rant. My annoyance should probably be directed at the Xubuntu project overall, or maybe XFCE, rather than the power manager specifically?

The power manager was never in charge of altering the X11 screen saver timeout. Tools like xscreensaver or xset can be used to change the default value set by the X server.

Now, xscreensaver has been replaced with light-locker in Xubuntu 14.04. On top of that, the Xubuntu team has included a simple GUI settings application (Light Locker Settings). It allows the user to change settings related to screen locking and blanking [1].

The bottom line is that the bug described in this report is actually a feature request, so it is unlikely that the change will be backported to a previous Xubuntu release. However, you can upgrade to a newer xfce4-power-manager version by following the advice in comment #57.

Hi Thaddaeus,

I appriciate that this issue may be fixed using xfce-power-manager-1.4 however only version 1.2 is available to Xubuntu 14.04 LTS users. You say to install the latest version from xubuntu-staging, but it specifically states on the page you linked to "Please DO NOT consider this PPA a main, stable source for the packages.". For LTS users it is NOT an acceptable workaround to install from unstable PPA's.

Is it possible to add the xubuntu-staging PPA, but allow it to only use it for the xfce4-power-manager application? If so perhaps you could detail these steps as I am not sure how to do this.

Otherwise, as you mentioned earlier this fix would not qualify to be added as a backport (as it doesn't specifically add a new feature), would it qualify to be updated as a Stable Release Update? I would have thought it would come under "Bugs which do not fit under above categories, but (1) have an obviously safe patch and (2) affect an application rather than critical infrastructure packages (like X.org or the kernel)".

As for my experiance with this bug, I can prevent the screen blanking using:

xset s noblank

or delay it using

xset s 0 6000

where 6000 is the screen blank delay in seconds.

However, this change does not persist after a reboot or system hibernation. My suscpicion is that a settings application is resetting xset values on log in, though I cannot confirm this.

For completeness, my Light Locker and Power Manager settings:

Yes iv used xset s off but it only comes back after reboot.

Please could someone explain how i fix it since you say its been fixed already. Im quite confused :-/

Thank you.

In Light Locker, just move the arrow in "Blank screen after" as far to the right as possible.

Spent days trying to fix this, looked at loads of solutions, and then finally found how to fix it.
I have an install of LXLE, and after switching every screensaver
setting off still got the locked screen after exactly 10 minutes...

Simply go into Synaptic and uninstall "xautolock", then reboot...
problem solved for me!

I believe the problem is with the Screensaver Preference Panel and not the Power Manager.

On the Screensaver Preferences.. 'Activate screensaver when computer is idle' Button when switched OFF, does not seem to work.. so beneath, where it states: Regard the computer as idle after: 5 minutes -- is still set for 5 minutes.

xset q | grep -A 2 "Screen Saver:"
timeout: 300

I have set my idle to 600 --10Hours

even then my timeout returns 28800 for some reason..(maybe there is a limit)
