Ubuntu :: Monitor Goes To Sleep ... Can't Disable "powersave / Screensaver"
Jun 14, 2010
I have recently switched to Ubuntu (10.04) after running my system on Centos for years. This mostly due to much quicker startup times. I have a software that runs as a public presentation software on a public "bigscreen" so my Ubuntu runs like a "kiosk" pc that's always on. When i switched to Ubuntu everything worked lika a charm besides the fact that the screen falls in to "sleep"/"powersave" or something.
I think that i have tried everything to prevent this. I use Gnome and i have set all the powersavings features to off. Ive tried turning acpi off and i also turn dpms off at login. Nothing seems to kill the "screen powersaving" feature. As a desperate act i tried to use a software called Coffeine, this software should prevent powersavings. I added Coffeine to autostart to activate for 48h, I need the screen to atleast stay on for 24h.. Does anyone have an ide what cuses this? Dont really want to go back to Centos now... My system basicly looks like this:

I'm running a fresh 10.04 x86-64 on a thinkpad w500, using the default video driver. The monitor shuts off randomly, sometimes while I'm using it and requires me to trigger sleep mode and waking up to bring back the screen. When it shuts off, everything else seems to be running. (i.e. its not going to sleep) I've turned off screensaver, sleep, hibernation and installed the Caffeine util to no avail.

I've stopped/killed/uninstalled all power related stuff like powernow, powerd, upowerd, acpid, gnome powermanager also turned off APM and ACPI support in bios. And after that I still have a problem: My display's backlight turned off after a long period of inactivity and there is no way turn it on. (Sometimes kill of Xorg helps, sometimes alt-ctrl-f1/atl-control-f7 however I need about half hour to get my backligh back). How to check I indeed removed all power related stuff.

Slackware 13.1, on a Dell... Opliplex GX260... running XFCE4, as root. Stuff runs fine. However, the monitor goes to powersave mode after 10 minutes of inactivity. I've turned off power management in the kernel, in the app., have checked the xorg.conf, checked everywhere I can think of, can't find where this is being set. how I can turn this off?

I just installed Ubuntu 10.04.1 32-bit on a Dell Optiplex GX280 with Intel P4 3.4GHz, 1GB ram, 40GB hard drive, it's connected to a 17" CRT monitor which was detected automatically. Anyways, I set screensaver to come on after 15 minutes, monitor to shut off after 30 minutes and computer to go to sleep after an hour idle. The screensaver came on and monitor shut off as desired but the computer wouldn't go to sleep. So I manually put it to sleep (clicked "Suspend") and it went down and came back up just fine.I then did a few other things like installed java, flash, vlc player and I noticed that the screensaver won't even come on now. What is going on???Running:
Code:sudo lshwshows under display: Intel 82915G/GV/910GL Integrated Graphics Controller. Again the screensaver and DPMS WERE working, but they aren't now. I don't understand why Ubuntu isn't doing what I asked it to do in Preferences. it's very frustrating

I have a really strange X (?) problem. My physical setup is:
Dell Optiplex 990
VisionTek 210 nV DMS59 PCIe video card (with a DVI splitter)
dual Dell P2411H monitors
I'm running OpenSuSE 11.4 (x86_64 fully patched) with the current nvidia drivers and kernel module. I'm running KDE and kdm in case that matters.
If I power off the two monitors, and then power them on again, the right monitor will come back on. The left monitor (which is the primary one... it's the one where the login screen appears when you are first logging in) reports that it is in power save mode. Wiggling the mouse, typing, etc., do not wake it up. The only thing that wakes it up is the detach the DVI cable from the monitor and reattach it (and sometimes it takes a couple tries).
I have used two (identical) video cards and splitters, and the problem occurred with both, so the problem doesn't appear to be with either of them. I also swapped monitors, but after the swap, the problem still occurred on the left monitor, and the old left monitor (which was now right) came on fine, so it doesn't appear to be a monitor problem.
I'm baffled. For now, I just won't turn off the monitors (or at least not the left monitor).

running 10.04 Netbook edition. I would like my screen to lock after the netbook goes to sleep but NOT after it enters the screensaver. is this possible? i use my laptop to read in the university a lot and to save power tell it to go into black screensaver after a minute of inactivity. if i enable the lock option i have to enter the password each and every time after the black screensaver activates. but if i deactivate this option and then put the netbook into sleep/hibernate mode it doesn't ask for a password (which i would like) is there any way configure separate passwords for these instances or are they firmly linked?

Anyone noticing intermittent problems with the screensaver not kicking in or the display not sleeping? This is in gnome under F11.I have the Power Management Preferences set to put the display to sleep after 30 minutes of inactivity and gnome screensaver is configured for 5 minutes idle time.On a regular basis, I'll leave my computer come back anda) the screensaver hasn't kicked inorb) the screensaver kicked in, but the power management features didn't kick in to put the display to sleep.It seems to be an intermittent problem and usually it goes away after I restart X, but then at some point it comes back. In the past, I've gotten in the habit of being logged in for weeks/months at a time but I find that I can't go more than a few hours without logging out and back in or else the screen won't go to sleep.

How can I disable the functionality that puts the computer to sleep when I press the sleep button on my keboard?
I keep hitting it accidentally and I don't even use a swap, so Ubuntu just stalls with a black screen.

I have Ubuntu 10.04, and I have my power settings set so that my display is never supposed to go to sleep, yet it still does after 10 minutes of being idle. Has anyone else had this issue?

Does anyone now if SMplayer is able to disable screensaver when playing video? There is an option to have SMplayer to do so within the settings menubut that does nothing, screensaver is still being activated after 5 min. Anyone managed to have the player do this? I am on KDE4 by the way.Kaffeine does disable screensaver but I do not like the KDE4 Kaffeine.

It's very disturbing when making a Kiosk application, every time the lock screen and screensaver shows up, also many popup + battery or updates shows up. Where and how can I completely disable the lock screen, screen saver and alerts via a configuration file or from the terminal? I have the tried following but nothing works: failed
vim /etc/default/acpi-support
;LOCK_SCREEN=true
failed
$ gconftool-2 --type boolean -s /apps/gnome-power-manager/lock/suspend false
$ gconftool-2 --type boolean -s /apps/gnome-power-manager/lock/blank_screen false
$ gconftool-2 --type boolean -s /apps/gnome-power-manager/lock/hibernate false

I found a few threads dealing with this subject about a year ago but none seem to have come up with a simple answer. I use vlc and one writer indicated there was an option in vlc to disable the screensaver when in full screen mode. However, I've checked all over vlc and can't find this option.I'm not interested in creating a switch using Terminal to do this manually. I just want to know if disabling the screensaver can be automatic when in full screen mode - like in Windows

Currently I have two 1920x1080 screens running in Twinview on my Geforce 275 graphics card. Want I want to do is a quick simple way of disabling my secondary monitor when playing video games or using xbmc to watch movies, etc. I've tried a few applets but they require the xandr function which I think Nvidia doesn't support.
Is there a way to disable this quickly other than loading up nvidia-settings and disabling the monitor everytime. I don't really want to use two seperate x sessions and xinerama due to the fact you can't use compositing.

I am running Ubuntu 9.10 on my desktop and everynow and then I get this annoying problem. If I walk away for a bit, just upstairs to use the bathroom, sometimes when I come back the monitor is off and the power light is blinking. You know, like what monitors usually do when they are still powered on but the screensaver is done playing. However, this happens to me well before the 10 minutes that the screensaver is supposed to end.
It does not always happen, and I can't really isolate what may be causing it, as I never take a note of what I'm doing when I go pee. HOwever, I rarely do anything other that run VLC, Chrome, Firefox, or OpenOffice Writer.
The problem is that the screen won't wake up. Moving the mouse does nothing. Jamming some keys does nothing. Trying to go to text terminal does nothing. I have to either REISUB or hold down the power button on the tower.

I am trying to install Ubuntu 10.04 on my PC using NVIDIA GeForce 9150LE graphics and HP w2207h monitor. After using the Wubi installer and rebooting my computer, i select the ubuntu boot menu option and it says it is preparing to continue with the installation. after a countdown before it begins, my monitor goes to sleep. i used an eMachine monitor that i used in a previous installation of 9.10 that worked fine and reached the exact same problem. When booting from a live CD and selecting try without installing the screen comes up with a blinking underscore, and both monitors went to sleep. I believe its a problem with the graphics chip, but i dont know how to fix it.

I just recently got my old box back and now I'm running 10.4. I've had some minor issues that I have got through but now there is one which seems to really be frustrating me. At any random time my monitor may go black as if it is in sleep mode. The problem is when it does this, no mouse movement or keystroke will wake the thing up. So I am forced to press the power button. When I press the power button the Ubuntu logo pops up on the screen as if it magically woke up but it is too late because now the computer is shutting down... When I go to System>Preferences>Screensaver I get to the options for the screensaver and I have about 2 seconds before that triggers the screen going black.
I can't even start until I know that my screen won't shut off at any random moment!

i would like to know if there are any good ways to disable and then reenable (the latter is key!) the screensaver so that it doesn't start when i'm watching movies with xine or when i'm watching flash things online like through hulu, videos, or so on. it's relatively simple to have a script run that will turn off the screensaver before starting a certain executable. but what about turning it back on again when the executable closes? and is there any way to detect that flash is running inside a browser window and then disable that temporarily?

Running RHEL5 and because of the environment that we are in we have to disable the users being able to change the screen saver. I have tried using the gconf-editor to see if I can disable it but don't know if that is the correct way of doing it. I also looked in /etc/xdg/menus and really don't want to miss with that.

I have persistent video tearing my second monitor (Mitsubushi HDTV). I have tried everything that was suggested with some improvement. I have no issue with tearing if I add the following to my xorg.conf
Quote:
Section "Extensions"
Option "Composite" "Disable"
EndSection
Is it possible to disable composite for one monitor only and keep it for the other. Or at lease is it possible to have compiz for one monitor only and disable it for the other.

Whenever I boot into ubuntu 10.04, my monitor just automatically goes into sleep mode. As soon as I select to boot into ubuntu, the monitor just sleeps. There's no getting out of it. Booting into windows works fine though, so the problem has to be ubuntu.

I upgraded a couple weeks ago and now my monitor doesn't go to sleep like it used to.
The settings in powermanagment show that it should go to sleep after 10 minutes.
Can someone point me in the right direction?
