Ubuntu :: Save Power And Avoid Heating By Powering Server Off Durring Day?
Jul 5, 2010
I have a server that only runs durring the hours the house is asleep, to avoid bandwidth hogging. I know there are ways to prevent bandwidth hogging, but I figured I'd kill two birds with one stone. My other goal is also to reduce power and cooling costs. My two computers between them make a very nice space heater in the winter, in summer they make it sweltering in my room.I'm sure it would be trivial to get the sever to power itself off every morning, but is it possible to get it to power itself on at bedtime? If not, I do have Wake on Lan working, is there a windows program that would allow me to send a wake on lan signal every day and then shutdown windows
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 will be setting up a computer for people who have very little experience using computers and I want to limit their ability to break things. I'm thinking Linux is the way to go but I don't know what distribution to use. I don't know anything about their hardware other than it is an old laptop. I don't have a lot of experience with Linux, but I would think that without sudo there is not a lot of things you can break.
What would be a good Linux dist that has everything out of the box? (flash, vnc, office, etc) How should I set up the user account to avoid giving them too much power, yet still allowing the computer to be useable for daily tasks? (Will they be able to update software?) I also want to be able to control the machine remotely since I won't have physical access after I set it up, so I am looking into ssh, vnc, (or a better alternative?).
I'm running CentOS 5.5 x64 and have just installed VMWare Server 1. I am able to create a new Virtual Machine, but when I go to power on the VM in order to install the OS (windows server 2003), either the host crashes/reboots (with "Run in Debugging Mode" turned on) or the VM simply does not start (with that Debugging box unchecked) and in the log there is an error along the lines of VMware Server unrecoverable error (vmx)
Out of nowhere my computer will not boot up. I get the message like this NMI received for unknown reason 29 on CPU 0. Dazed and confused, but trying to continue Do you have a strange power saving mode enabled? NMI received for unknown reason 39 on CPU 0. Dazed and confused, but trying to continue Do you have a strange power saving mode enabled? I read something about it being the video card, so I took my old one out which it being an ati, an replaced it with an nvidia.
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 have created a custom linux distro originating from the ubuntu server edition and have slim as the login manager, and openbox as the window manager. When it goes into power save mode and turns off the monitor and I move the mouse to wake it up it just goes to the shell with a mouse cursor on it. How can I get it to go right back to the openbox window manager?
I have a Dell Precision T3400 workstation (Nvidia Quadro NVS 290) with the kmod Nvidia driver installed. Everything works fantastic for power saving, the screen saver comes on , then the monitor blanks after a while. The only problem is that the monitor itself (Dell E228WFP) never goes into standby. The power LED stays green instead of orange. Worked fine under FC8, only noticed it recently under FC10.
i am trying to install rhel 6 (86*64) on my windows 7 (AMD Sempron 145 processor) using DVD iso image. after selecting keyboard language and it goes to ther rest of the process for 20 seconds and then the monitor goes to power save mode. trying to input with keyboard or mouse does not seems to be helping. i have changed my windows 7 powersave options to "never".
I'm not sure this belongs in this forum as opposed to the hardware forum, but I do not beleive this is a hardware issue.I want to stop the scrren from blanking and going to power save. I'm running 5.3_x86-64 and I'm using the nVidia drivers direct from nVidia called NVIDIA-Linux-x86_64-96.43.13-pkg2.run.
So far, I'm added DPMS off in /etc/xorg.conf, removed all the screensaver packages and all the power management packagesbut the screen is still going blank after a time of inactivity.What else do I need to do? I can not allow the screen to go blank, there should be no screensaver or power management and the machine should stay in a completely awake and ready-to-use state at all times.
Is there a command to turn off my Broadcom wireless card to save power. In Apple, the have an Airport off listing under the airport menu, Is there something for Fedora?
Ok so I am a total newbie at Ubuntu Linux and I'm having problems I don't know how to solve.
1.) Up until yesterday this wasn't a problem, but after a power outage while I was connected I am now unable to connect to the internet anymore as it says "Networking is disabled", how do i enable the "networking"?
2.) Another problem I am having is that I am not able to dim the screen in order to save power among other uses, I've looked around but haven't been able to find a solution, I am running ubuntu on a Gateway M-Series Laptop.
3.) Finally, since installing linux I have been unable to listen to music or any other sounds through headphones or speakers, when i connect something into the audio output, the outer speakers do shut off but no sound is emitted through the speakers/headphones, and yes i have tried multiple ones to make sure it wasn't the headphones or speakers.
Ubuntu randomly switches off. I eventually found out that it happens when my system is over loading. If my memory goes up to 100% use or CPU, Ubuntu powers off. If there some software that I can download to prevent my system from using 100% of its power, so it doesn't power off?
I'm building up an old PC for a friend. The PCs hardware is quite old. I decided Xubuntu would be appropriate - works well! Currently the only issue I'm having with it is that it does not shut down correctly. The last message I receive is "System Halted!" which stays on screen while the rest of the system is unresponsive. Initially I thought this was an ACPI issue, I was told to add acpi=force and lapic to the boot options but unfortunately this has not fixed the error.I'm really stumped with this issue. By coincidence I have a similar motherboard (May even be the same mobo) in a different PC which had the same issue but insisted that ACPI needed to be forced because the BIOS was older than 2000 (1997).
Because I'm stumped, have some output from various commands I've ran. Code: ~$ lspci 00:00.0 Host bridge: Silicon Integrated Systems [SiS] 730 Host (rev 02)
I've just installed F15 graphical desktop on a brand new 64-bit box. When I use the Alt key in the User menu to display the shutdown options and click the "Power Off" option, the box shuts down, but then immediately restarts. Is that supposed to happen? How do I get the box to not restart after powering down? Kernel is 2.6.38.6-26.rc1.fc15.x86_64. The box also auto-restarts after root command shutdown -h now
I've moved a web site from one server to another.I'm also moving the domain name to the new server.In Apache I've got the web site configured up and running with no problems. What I'd like to know if this is possible. I'm wanting to avoid a complete web site rewrite. I've looked into mod_rewrite but I don't think this is right.I only want the web site to look aesthetically pleasing. So if it's not possible so be it. (I'm not a programmer but do have access to the code)
I bought a new Hp Pavillion DV6T. For the most part, everything worked right out of the box with ubuntu, but the computer seems to be heating up really quickly for no reason whatsoever even if I'm not doing anything intensive. Why this is happening. The fan always seems to be running at full blast. I logged onto windows for a minute to see if there was any difference in heating between the two OSs and windows seems to run much cooler and much more quiet. On a side note I'm thinking of returning the HP and buying a dell XPS 15. I hear they are more compatible with ubuntu and are better built.

Problem is that with all kernel-xen x86_64 from current kernel-xen-2.6.18-194.26.1.el5.x86_64 back to kernel-xen-2.6.18-128.el5.x86_64 after kernel boots monitor goes blank and says "no video, going to power save".
Google finds similar problems and sugestions was to add "nomodeset". With this option monitor also blanks after kernel boot, but says "out of range". Other options to modify xorg.conf does not apply, becouse there is no X installed.
I try with multiple monitors, without success. This happens only with 64bit kernel-xen. All other 32 and 64 bit kernels and 32bit kernel-xen works fine, video is ok. This happens to 6 servers, all are same hardware, used as cluster. Installation with "linix text" allways is fine, video disappears after first reboot when standart kernel is booted. I also tryed with almost all possible "vga=xxxx" kernel options and none of them works.
I know it might seem a stupid question, but i'm gettin' nuts over avoiding webapp auto startup on Tomcat restart.i have a server, used for developing. Its tomcat has a bunch of webapps deployed. MOst of them are old/kept just for the sake of it, and I would like to avoid TC to start them on start / restart. How do I prevent a context to autostart on service start / restart?
I would like to go in the config files and selectively choose the apps to start. When tomcat is started, if anyone needs an app to be started, i would like to do it from the manager. But when I restart TC, i would like my choices to be up and running only.

Installation of Ubuntu 10.10 Notbook edition make my lappy extremly hot in comparison to Windows 7, which includes degrading my battery performance from 3 hours to 45 min. As my CPU uses is normal, i deduce that my Graphics might be the cause of the heat and power consumption. Tried installing proprietory drivers from Get Software -> System -> Additional Drivers, which maximized the problem. My screen keep freezing now and then. So i uninstalled the driver and downloaded ati-driver-installer-10-11-x86.x86_64.run from ati site. While install it has issue of its own. The text written in the installer is invisible. [A print screen is attached]. This is to mention that the core fonts are installed in the system. I shall be glad if anyone have the solution for my problems
1. Over heating and battery backup issue. 2. ATI catalyst font issue.
i just want to prevent from now on from all users maybe even root from adding other users to groups like wheel for example. I also want to know how can I prevent from all users to create new groups or add users to new one.real
I have an office workstatation that I installed with linux and ran a 8-core job. It is expected that the job to finish in 6 days but then it stopped after 2 days. The reason is that when I came to office this morning the workstation is completely turned off for some reason. Since the air-conditioner is turned off in the office overnight, I suspect the temperature is too high for the cpu. Is there a script to output the temperature to a file periodically so that I can pinpoint the exact cause of the shutdown ?
I want to run Ubuntu Server Edition just at home, however to avoid having to reinstall it in the future when i upgrade hardware, I was thinking of virtualizing it first. Are there any minimalistic virtualisation solutions available at the moment for this sort of purpose? Or even better a linux distro just for this?
I've set a two-node cluster using Pacemaker/OpenAIS. I have only one network and if I break this one, the communication between node is interrupted ... With a ClusterIP resource, when network is breaked, then each node start the ClusterIP => 2 same IP .. Is there a way to define the prefered location of a resource when connection between these nodes is broken ?
A <==> B
If one of the node lose the network, then follow a previously written rule : start resource on A (for example). B will know than it's not the prefered node and so, will stop to serve. Possible ? This is because if both node are connected, but a problem between these node occur and client can join both node ... then the split brain is problematic ... A better solution is to add a rule when the split-brain occurs : all node wich can't reach the gateway have to stop all resources ... And so, if it's A wich lose the network, service will start on B and only B without any problem ...
CPU fan apparently is not working with Debian (or Kernel, I don't know who's responsible for ACPI devices management. ).After setting up lm-sensors to show core temperatures, and running a simple "while(true);" C program, I noticed the fan doesn't turn on until the temperature reaches 80 degrees Celsius, and when it does, it runs at what appears to be full speed (VERY noisy). Also, it stays turned on at that speed even after temperature gets below 35 degrees Celsius. The only way to turn it off is to put the computer to sleep and wake it up again, but if I do the same procedure, it happens again.
I think it is related to some compatibility problem with ACPI devices because when I turn on the computer, I can't get the Fn keys to work, but after I suspend and wake it up, I can control the brightness using the Fn key and use the Play, Pause, etc. buttons. I read this has something to do with ACPI issues, the same as the fan control issues, because "try to suspend and wake up the computer" is something people usually tell to others with this problem (I assume just to confirm the diagnostic).Everything works fine on the pre-installed Windows Vista that came with the computer. It's definitely a compatibility problem.
I've read a lot in forums, even here, but I couldn't get any solution for this. I installed toshset but asks me to enable a Kernel module which I have no idea of how to load. I have no idea of how to load a Kernel module in fact.Also, I didn't want to believe, but I read there's no solution for this (at least, not one which doesn't involve a lot of knowledge on the matter).I'd like to stay with Debian, so I'm doing my last try here before installing other Linux Distro. I hope this problem is about Debian and not all Linux distros.My laptop is a Toshiba Satellite L355, Intel Pentium Dual Core T3200. I bought it in the end of 2008, so it's kind of old.
to avoid automatic start of this mail server (I use qmail). After several months, I did a reboot and exim is started! Looking at the history, I found this command:
Quote: dpkg-reconfigure exim4-config
Maybe this command has restored the init script of exim?
First issue is, now that I am running Debian "Squeeze", my laptop runs much hotter than before. Its definitely hot on the very bottom compared to when running Windows. Once the system begins to heat up, the fans start spinning faster, the system gets louder, etc.
Second issue is battery life. I am able to get 5 hours out of the laptop in Windows, but maybe 2.5 hours in Debian. I am assuming that these two problems go hand in hand. Now from experience with PC hardware, I know that the newer chips scale their frequency and voltage depending on demand. I don't think the computer is doing this correctly when running Linux.
By running cat /proc/acpi/processor/CPU0/throttling
I see that the CPU(s) are in T0 state (or 100%). Manually setting the frequency doesn't change anything either (via the gnome applet). Am I diagnosing this correctly?
