OpenSUSE Hardware :: Low Level Power Management Screen Saver Removal
May 28, 2010
I run V11.1 on a minimalised install on a stick with TWM, no KDE at all but I cant get rid of the screen shutdown after about 20 minutes. Also I have several other boxes with v11.1 with KDE and still cant get rid of these screen shut downs.I dont believe this is coming from the bios in these machines. they are all Intel D945 MBs with some sort of Nvidea cards.
My app normal runs with no user mouse or input and is pocessor intensive.I would like to retain the power shutdown and reboot capability from comand line.I realise its not as simple as pulling symlinks of of the init levels in the new complicated distros, but I was suprised the non kde twm install still shuts down the screen.So I want a low level level fix that will remove anything kicked off by init that will derate the system performance or turn off the screen.
I have recently loaded Ubuntu 9.10 which runs perfectly, except for the power management system.I go into the GUI power management screen and tell it to use the screen-saver after ten minutes, but NEVER suspend/ hibernate but it suspends/hibernates anyway,sometimes after an hour, sometimes hours later.Is it possible to keep the screen-saver but disable the rest of the power management system?
I am a brand new user coming from the MS environment. My impression of openSUSE is that it is like moving into a new house that is well built but the rooms are full of half-constructed self-assembly furniture and appliances without any specific instructions. Nor is it clear which does what and whether all are needed or not. There is a town hall down the road where fellow homeowners gather to discuss what each has managed to deduce about putting their own furniture together. The town hall has a sort of library where thousands of pieces of paper with instructions are stored in an ad-hoc filing system
My latest problem is that I have created a screensaver via the "Configure Desktop" application and set "Enable display power management" and set some timeouts.However, I seem to be asked for a password to unlock the screen when I come back to my computer. I have spent 2 hours trying to find the place where I can disable screen password locking but to no avail. I am perplexed and frustrated at how such an obvious function is so ****ed hard to configure. This is the impression I am getting of Linux in general - it is novice user-hostile and badly organised.
I have a computer(Fedora 12 Kde4) playing flash,but the screen will get into sleep mode after a few minutes.But it will not sleep when it plays movies.So I want to know: is there any way to active the screen every few minutes so that the screen will not get into sleep ? It is a remote computer ,all I can do is to send cron job to it ,no SSH. So commands is the best way,but please do not interrupt the flash ? I run this command "xrefresh" to refresh the screen ,but the screen still sleeps.
I have an issue where the screen on my laptop will not shut off with the power management tool. The Default Power Manager does not have an option for this.My screen will go blank after a set amount of time, but the lcd-backlight will remain on. I would want the power manager to shut the screen off completely (including turning off the lcd backlight) without shutting down the computer it-self. So the computer can continue to do what I left it to do in the case I forget to close the lid. With the screen shut off completely, will preserve the life of the back light and reduce power consumption.
Is there a better power manager app that will allow me to do this a tweak to the existing default power manager that will allow the functionality I am seeking? laptop was perfectly able to do this under a win-xp environment, so I know the machine is physically capable of doing this. Note: My WinXP OS and Ubuntu OS are on seperate physical drives so there is no dual boot issues. So when I am using one there is no trace of the other present
I'm running Squeeze with Gnome & GDM3. After 1 h my laptop automatically suspends while in the login screen (GDM3; so no user login). I want to prevent that, since this machine also has a server role. how this can be prevented?
I have Fedora 15 gnome 3 installed on my new laptop. When my system runs on battery my power management keeps changing my screen brightness. It keeps dimming my backlight. In the GUI of Power Management I cant find any option to change this setting. How can I do that through Command Line
On a fresh install of Debian 8 with XFCE (with a NVIDIA GeForce 210 according to lspci, and a P7P55D Asus mainboard), I just added a second monitor. This second monitor does not switches off even though the first one does due to the Screensaver Preferences → Advanced → Off After 3 minutes.
The new screen is a HP Pavilion 25xw plugged in using a HDMI cord.
The old screen is a Philips 190S plugged in using a VGA cord.
The new screen (HP on HDMI) only goes blank when the old one (Philips VGA) turns off.
Two tests:
- on the same machine, I also have Windows XP: both screens turns off at the same time with the power management. - I tried on Debian: Code: Select allsleep 5 && xrandr --output HDMI-1 –off
It turns off the second monitor, so I know that it is possible to turn it off from my Debian.
How to set up the system so that both monitors power off when the machine is not used?
I have selected to power down the monitor after 30 minutes, and suspend the computer after an hour. It does not work. With Beagle not running (more below), the monitor powers down after 30 minutes as expected. But then later (probably after an hour?) it powers up again and stays that way. Not exactly what I envisioned.I have removed Beagle from the set of running processes. The process list ("ps ax") shows Beagle as a serious consumer of CPU time, far more than any other process. (At termination it was at 500:00; the next most hungry process was /usr/bin/Xorg at 10:00. Most barely get over 0:01.) It introduces these problems:
1. after some amount of system idle time (it is about 5 - 10 minutes) Beagle starts consuming vast wodges of CPU time. I have dual core AMD 5200; both CPUs run up to about 70% usage until I do anything, like move the mouse. Then the usage drops back to the usual 5 - 10%. 2. When Beagle is thrashing the CPUs, the power management monitor thinks the system is busy. And powers down nothing.
However, again, that's just a guess from what would make sense.
So my first question is, is there a way to know this information, and is there a place were these critical points are set, or are they all from the UPS. I'm guess there are some settings somewhere because not all UPSs are going to be able to supply this information. Some may only supply a battery level or some just a warning message so there must be some configuration for this somewhere.
My 2nd question is a probably a little harder to know the answer to. After getting this to work I wanted the added functionality of nut so I installed it and got it working and it uses the On UPS Power panel as far as I can tell.
Through all the nut documentation it talks about powering down on once the battery level reaches the critical point (I assume that is "When UPS power is critically low"). I don't see anywhere however where it mentions handling "When UPS power is low" so now the question comes up, will it have any effect at all with nut installed, i.e. what will happen?
Of course I can just "pull the plug" and start finding this stuff out but Linux is all about having the information and "knowing" (assuming all works as it should) I am asking to find out where this information would be -- and become smarter for it
I've got openSUSE 11.4 64 bit system with stable 2.6.38 kernel and KDE 4.6.3. Problem is that when I want to change some settings in the power management (like brightness, screen energy saving time-off, display dim), they doesn't seem to save, even after the X restart and full reboot. It's seems like screen energy saving is set permanently for couple of minutes, don't matter what time do i set, it just discards my settings, even they are correctly viewed in the gui.
I've just installed openSuSE 11.2, and I need to disable the feature that causes the laptop to suspend when you close the lid (and it's plugged in to the wall). I've already done this for my user profile, and I've attempted to do it for the root profile, as well, but when the GDM login screen is shown, the laptop still suspends when you close the lid.
After I have installed the Education package I cannot put my HP Pavilion laptop to sleep mode. I opened the Power Management and I can see the red light next to "CPU can be turn off". Also, when I close laptop lid it doesn't go to "Suspend to RAM" mode it still spin the fan.
I tried to achieve this by disabling 'Enable display power management' checkbox in the 'Configure Desktop -> Display -> Power Control' KDE configuration dialog. That didn`t help and display still goes into standby mode after some period of inactivity. Also, I tried to disable dpms functionality by calling 'xset -dpms'. That didn`t help too. Note that 'xset dpms force standby'
I am trying to reduce my uptime of my servers. I would like to have a way to bring the systems down during off hours, an come back online during first use. I know about WOL (wake on lan) found in the bios, but it seems as if the OS is missing something to complete the configuration.Are there any good docs (of which I havent found any yet, which is why I ask) on this topic? How about best practices to assist in power management?
Just found my PC with screen fully lit a good half-hour after leaving it. Went into "system settings" and checked the power-management settings and, as I expected, there were no management profiles. "Here we go again" I thought and logged off and then back on again. Checked the settings and there was "performance", the only one available. As usual in this situation, I'd tried "restore default profiles" and there were none.
Why does this profile keep getting lost in this manner? Where is it (and defaults if any?) supposed to be stored?

I want to "build" a new backup solution for my home LAN. I have 3 openSUSE machines at various versions and 1 File Server with openSUSE 11.4.My plan is to plug a eSATA or USB3 docking station on the file server and then take backups from the clients either via rsync or Amanda.Since the backup will not be a daily activity, I would like to have the option to run the backup during night, and automatically, BUT, without any action from my part. So, I would like to attach a large external HDD on the machine and then:Power on the docking station/HDD.Perform the backup from the Amanda Server or rsync scripts.Power off the docking station/HDD.Do you know any docking station that has a "linux" power management?If not, how do I power up/power down from console an eSATA or USB HDD?
I've got a rather annoying problem with OpenSUSE 11.1 x86_64, I can't turn off the display power management! I've tried from the KDE 3 and 4 settings as well as GNOME, and finally YaST2. There's nothing in monitor's controls (the buttons on the monitor itself). The actual GUI controls in KDE/GNOME/YaST2 work (as opposed to being grayed out or disabled) and the system doesn't complain when I hit apply/OK, but every time I disable display power management, I wait about 15 minutes and sure enough, the screen blanks. I've checked and made sure the screen saver is disabled, I've looked for a setting to change in the YaST2 sysconfig editor and the kernel settings app, but can't seem to find anything. The only other thing I can think of is to try the acpi=off kernel boot option. I'd rather not resort to that. Anyone know if there is some super secret hidden setting somewhere that might be overriding everything else? Could this be some sort of ACPI incompatibility issue?
On the last release, I had this app installed where I could pick my power profile. I could use power conservatively, and performance would suffer a bit, but longer batt life,or I could have it automatically detect, or I could have the apps use all the power they want and then some. I'm looking to reinstall that app. What was the name of it?I can't remember, and so far, can't find.
I have never been able to use the Screen Saver in the Desktop settings, as even clicking on a Screen Saver, crashes the whole Desktop Settings.Here is what I get:
I'v been unable to set the screen saver timer since I can't find it. I'v tried the suse wiki, no info. Right-clicking the desktop or Admin Yast doesn't have it. Where are the timer settings?
I'm wondering if there is a method for leaving the screen saver set to appear after, say 4 minutes, but to NOT have the screen saver activate during a streamed video. For example, any time I wish to stream a video through Firefox, I must open screen saver settings and deactivate. I was wondering if there is some way to maybe lower the priority for the screen saver below Firefox or Flash player, etc. Or if there is another work-around that is simpler than monkeying with the settings every time.
I haven't noticed this problem when using media players to mount local files, such as vlc. I'm running 64-bit KDE 4.6.4 Tumbleweed (from 11.4), FIrefox 4.0.1, Linux 2.6.39.1-33-desktop x86_64. Last 'zypper dup' was done yesterday, 6/28. Sorry if I forgot any important info.
I recently read that windows 7 has come with a special "power saver" mode which will ensure your computer does not take up any more electricity than you needed ( Control panel -> system -> security -> Power options & select power saver power plan) , Does ubuntu have this feature ?
I can't login after the password-protect-screen-saver comes on during a download.The screen is black, the cursor arrow moves with the mouse, but no login window.I have no idea what is wrong but it seems to correlate with this combination.
I have a screensaver set to run after 10 minutes and then the screen is set to turn off after 30 minutes, but it seems that it never consistently stays off (after the 30 minutes), and very often turns back on and runs the screensaver instead. It seems to be in an endless cycle without me doing anything to wake it. Is there any way to fix this? It's killing my power usage. Karmic, core2duo, nvidia 7600GT gfx cards using latest nvidia drivers (but also happened on 190, and I think 185)
One very specific issue regarding KDE in OpenSuse 11.3
- when I close the lid of my laptop or get into a screen saver mode, sometimes when the xserver comes back to life it basically goes back to the KDE login menu (log out) without any warning...
I have looked at the detailed settings and power performance management but nothing there.... I am in fact in "don't do anything" mode (power management) but this does not seem to do much.
