I recently installed the first non-virtual Ubuntu server in our office (to put it in perspective, it's outnumbered several to one by Windows servers). It had an inexplicable array failure, and now it's been retasked to run VMware Server for testing purposes since we don't trust it at the moment. For the sake of ease of use, on this server I decided to install Xubuntu desktop x64, rather than Ubuntu server as I've done with a couple others.
This server is on an old school 8-port Linksys PS/2 KVM. It's got a CRT monitor in the middle of a rack of somewhat aging equipment. The problem I'm having is somewhere between the KVM, this old monitor, and some power saving... when Xubuntu tries to put the monitor in standby, instead it gets this vertically scrolling garbage. The Windows servers in this rack don't have any problem putting it to sleep, but I figured I might as well just turn off DPMS on this particular server.
So I logged in via SSH, stopped GDM, generated a /etc/X11/xorg.conf, and changed Option "DPMS" to Option "NoDPMS" which according to the manpage should take care of it. I also changed the GDM video mode with this xorg.conf so it's definitely being used. Following some other suggestions I found in my search, I issued "xset s off" and "xset -dpms" but this hasn't disabled monitor power saving either. I've been restarting GDM each time I change something. 5-10 minutes later it's scrolling garbage again. What's it going to take to turn off monitor power saving at the GDM logon screen?
running PCLinuxOS 2009.1 on my main machine : AMD Phenom II 545, 3GB DDR2, ATI Radeon HD 4870 512 GDDR3, 1 x 250GB IDE, 1 x 1x 250 GB SATA, 1 x 160GB SATA, 1 x 500GB SATA.What I want to disable are the HDD's powering down after a while because when I come back to work at my machine, it is painful to wait for the HDD's to spin up again. I also want to disable the screen from turning off. I have removed DPMS from myxconfig, but it as made no difference.
I am using Xubuntu 9.10 on a nettop as a X11 terminal.In order to do that, I created a custom session script that runs some commands instead of starting xfce4-session and the likes from GDM. When I boot this nettop, GDM automatically logs a dummy user in (called "test"), and runs a script that does "xhost +", and opens a small X Terminal to keep the X session alive, while some other computer sets the DISPLAY environment variable to point to <nettop>:0 and runs gnome-session.
My trouble is that after 10 minutes of idle, the screen is blanked(power saving I presume). I tried to add "xset -dpms" and "setterm -blank 0 -powersave off" to my startup script, in vain. I want my power saving options to be configured on the remote computer, not the nettop. How could I prevent X/GDM/Whoever from blanking the screen ?
I am planning to make a home made NAS running ubuntu server 10.04 LTS. Nothing fancy, simple samba with open access for all and openssh for admin access over the network. The NAS will not have heavy traffic, two home computers with occasional access, just to serve as central location. I am in doubt which CPU to use and I am after both budget and power saving solution.
1. I have an old Athlon Clawhammer I can use but the TDP of 90W is putting me off. I can also use existing 2x512MB DDR-400 memory with it. The board would be new. 2. I would rather invest in new mini-ITX board with built-in dual-core Atom D525 (TDP 13W), VGA and Gb ethernet. I would add 2GB DDR3-1333 memory.
Since I would need a new board for the Clawhammer too (current one doesn't have SATA), I am more attracted to option 2. Would the dual-core Atom be enough running this simple home NAS? I think it should but my experience with ubuntu server is limited.
I intend to buy a UPS for personal use. I have a slackware 13.1 machine on a quite old pc, and what I would like is just the PC to being turned off after 5minutes every time there is a blackout. I have found the APC Power-Saving Back-UPS Pro 550. However I don't know if there are drivers for slackware.
I work on Ubuntu 9.04 and our application requirement is not to go to power saving mode when application is running. I added ServerFlags section to /etc/X11/xorg.conf Section "ServerFlags" Option "blank time" "0" Option "standby time" "0" Option "suspend time" "0" Option "off time" "0" EndSection
This didn't help. Then I tried following commands gconftool-2 -s /apps/gnome-power-manager/ac_sleep_display --type=int 0 gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled --type=bool false I see that it works fine only if I change settings via Settings>ScreenSaver>Power Management in gnome. I wan to do this via script. Can I do this? Which file gets updated when I change display settings via Settings>ScreenSaver>Power Management.
I am running openSUSE 11.2 x86_64. I am processing work units from Folding@home on this pc. Strange thing is, when I actually leave the pc alone and working on folding@home, my performance actually drops instead of going up as I would expect. I believe there is some kind of powersaving feature I cant find or something else that's hurting quite a bit on the PC. I am talking about maybe 20-30% performance loss. PC in question is: Athlon II 630.
Already deactivated Cool'n'Quiet from the BIOS. Got no fresh ideas on what could cause this weird behaviour.
Update: Code: [22:05:52] Completed 260000 out of 500000 steps (52%) [22:18:28] Completed 265000 out of 500000 steps (53%) [22:30:41] Completed 270000 out of 500000 steps (54%) [22:40:20] Completed 275000 out of 500000 steps (55%) [22:48:16] Completed 280000 out of 500000 steps (56%)
PC was "idle" working on folding and I came back at 54%, see the huge difference? Frames were taking about 13 minutes each when "idle". When I am using the computer, frames are done within 8 minutes.
All of a sudden today there was no display on my Ubuntu PC. It seems to be powering on - I get the LG screen when the monitor is switched on - but it goes into "Power Saving Mode". How do I diagnose this? I already unplugged and plugged. Monitor is connected to a graphics card - no change when I switched to VGA.
I've recently changed to Debian from Windows, it's a really great adventure so far, but I have one problem. So as I see you can set your monitor into "Blank Page" after 10 or any minutes to save power, like in Windows. 10 minutes passes, without any movement my monitor's led turns into orange and the monitor turns off, that's great, that's what i want.
But after a few seconds the led turns green (like when it's on), and it brings up a little box : "Power Saving Mode" (just like it did after 10 minutes), and it turns off, and then stars again from the beginning . And this goes on repeatedly until a move my mouse to get back from "Blank page" state. (It's like the monitor tries going into power saving mode, but it gets always a little bit of power, to show that text box, and start all over.) So what can I do? I use debian 8.0 "jessie", and my monitor is a LG L1750S(with Nvidia GeForce 9600 GT).
I run Ubuntu Netbook 10.04 on my EeePC 1005HA. I'm going to get a SSD for it eventually, but I can't afford one right now so it's running from a 200GB hard disk I scavenged off a dead laptop.
I went in power management and set the option that says "spin down hard drives whenever possible", but this accomplished a whole lot of nothing - whenever the computer is on, the drive's spinning. I ran hdparm -y and the drive clicked off, and then promptly spun back up after a few seconds. Iotop shows occasional tiny bursts of activity from "jdb2/sda1-8", which I don't really know how to interpret, but I don't have anything weird installed so I'm assuming this is normal system operation.
Now, what I need is some sort of application, utility, command - anything - that forces the computer to keep all filesystem changes in RAM with the drive shut down; every five/ten minutes or so (this would hopefully be configurable) it spins up the drive, dumps the filesystem changes to it, and spins it down again.
I realize this presents data loss risks related to crashing and poweroffs when the cache hasn't been dumped to disk, but I'm willing to risk it as Linux never really crashes at all, and since it's a netbook power failures won't cause unexpected shutdowns.
when my monitor turns off after 30 minutes, I cannot do anything after. We're talking complete lock down of Ubuntu 10.04 64-bit. Not even alt+printscreen+REISUB reboots the machine; I have to do a hard reboot (which sucks and is hard on hardware).
I've covered a little of the exploration of this in another thread here. Unfortunately no replies.I've now installed as many power-saving features as I can get to work including laptop-mode scripts and my Asus Eee PC 900 has the battery lifespan of a gnat (2 hours 39 mins of extremely light usage including a long period of inactivity although with wireless turned on, from fully charged to battery cutting out, annoyingly this time ignoring my script that registers a critical battery APCI event and shut it down safely).
So, basically is my new Asus Eee PC 900 the worst designed netbook ever, or is linux just not supporting it's power-saving features? It is actually the version that comes with Asus's own linux distribution on it, but I've installed Arch.
[Code]...
What then are the power-saving options left available to me? How can I extend my battery life to long enough to check an email? What out of what I've said ins't working that really should?
I am trying to figure out why, i need to restart/reboot ubuntu in order to reconnect wirelessly after being in power save mode. It works fine before the power-save mode and fine after the restart. Is it an IP issue?
So I've come across several tips to optimize battery life on Linux. [URLs]. In addition to undervolting, I would like to underclock. Is there a way to control CPU speed outside of the BIOS via some software control in Linux... or some sort of boot manager? I would like to boot to linux using underclocked speeds and have Windows running full blast. Is there a way to run Linux completely in RAM? I have read that saves on power consumption from the hard drive.
I am running ubuntu 9.10 and was wondering how to disable write access in python. I want to stop .pyc extensions from saving every time I run a .py file.
My RHEL5 server is sync with NTP server. But we dont want to follow Day light saving. Is there any option to disable it. Like in windows you can uncheck the option if you dont want to follow day light saving.?
I just got a new keyboard the other day, but it has a horrible button saying "Power" which as it says, makes ubuntu shut down without saving anything! How can I disable the button? This is the second time I have accidently hit it.
I am wanting to completely disable Power Management, can I do it through the GUI? I am a former OpenSuSE user & am use to YaST. So it is a little hard finding ways to edit some settings.
So my display keeps dimming on even when plugged into the charger.The option to dim display is unchecked in power preferences, it gets really annoying when I'm trying to watch a movie.
I have Lucid Lynx with Gnome and Kernel 2.6.32 installed. Which probelms can I get if I disable Power Manager (Power management daemon) from the startup?
BTW does Code: xset -dpms s off do the same thing like disable Power Manager in the Starup Applications or DPMS is just for the Monitor?
I have a few machines set up and running Red Hat 4.1.2-42 in a computer lab. I also have a single test machine running the same version. The machines in the lab work flawlessly.However, when machines are on the login screen, they don't go into power saving mode. That is, after a certain amount of inactivity, the idle login screen should be replaced by a black power saving screen. But this does not happen. The monitor should go into standby (the little green light becomes orange, and the whole screen shuts down until you move your mouse again...you know the drill).I know this is supposed to be the case because this works on the test machine. It just doesn't work in the lab. I think it has something to do with gdm, but I can't for the life of me figure it out.
Under "Power Management Preferences" > "On Battery Power" > "When battery power is critically low" : We have several options : Suspend, Hibernate, Shutdown; but we don't have the do nothing option.Does any one know if i can disable all these actions so the computer will do nothing when the battery power is critically low? May be by a terminal command?
I need to disable the automatic power-off on shutdown so I can just withdraw the power myself. The reason for this is that the machine should power on itself when it gets power (which is accomplished by Resume on Power Failure in BIOS). I learned that I can turn off ACPI and APM by using the corresponding boot command options. Does this have any negative effect other than disabling standby etc.? Is there another easy to accomplish solution for this problem (maybe using linux from a readonly partition and make sure all programs are closed before I withdraw the power)?
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.
I am having a weird problem where if I don't touch the mouse or keyboard after logging on, the power manager settings are being ignored. I disabled turning off the display and screen saver from the Gnome utilities, but after about 20 minutes my screen blanks and my wireless network connection gets disconnected. This is on an HTPC, so I'm usually not near the mouse or keyboard, and unfortunately button presses from the remote control don't count. Media players like MPlayer will prevent the screen from blanking, but if I'm listening to music (where the music is served over the network from another computer), this means that the screen will go blank and the music playback will freeze as the network connection is lost. If I touch the keyboard just after booting it doesn't blank the screen or disconnect my wireless, but when I forget it's very disruptive.
I am running Debian Testing (Squeeze) with a Gnome desktop environment. I'm using gdm3 to log in, but I have it set up to automatically log me on. (I use gdm on my desktop, also with Squeeze, with it configured to show login screen instead of automatically logging me on and it still displays that behavior) I have attempted the following to resolve this issue to no avail:
Disable DPMS for my screen and monitor in /etc/X11/Xorg.conf Set all the timeouts for blanking, power down, etc. to 0 in /etc/X11/Xorg.conf Flat out disabling the DPMS extension. (so it's still blanking, even if it's not actually turning on power saving mode) Putting "xset s off" in ~/.xinitrc Disabling powersave with setterm in ~/.xinitrc Removing gnome-screensaver and gnome-power-manager from the startup items.
Edit: Actually, the wireless issue seems to not be related. It disconnected again, and after some searching with the error message I saw in dmesg, it looks like others have been having the same issue. It seems to have been coincidental that it was acting up when I was testing the screen blanking issue, and hasn't given me as much trouble lately, so it seemed like it was correlated.
I want to switch off 3d i.e. dri on my laptop to save power. There is a bug in the intel video driver that makes it generate excess wakeups and thus increase power consumption. I don't use 3d so this is very annoying.
I have tried modifying /etc/X11/xorg.conf to insert an "NODRI" option in the "Device" section and have commented out both of the "load dri" commands in the "Modules" section. No go. When I look in the xorg log, these changes are seen but not acted on. The system appears to have hardwired defaults set somewhere which are difficult to override. It appears to be a new issue because with Karmic one still had control with xorg.conf.
Just generally I don't like changes like this because it is not documented on the wiki where and how to change the defaults in Lucid. Linux was supposed to be easily configurable so IMHO this is a step backwards.
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'
One of the PC having Ubantu gets disconnected automatically from the network.As we do in normal windows is that we get to the device manger and select the LAN card properties and check off the power management check box similarly how can be do this thing in a linux OS.
