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 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.

1-Is it better to get suspend on ram or suspend to disk ?
2-Will the PC resume on mouse click or key push ?
3-When suspended, is there a way to wake up the PC from the network ?
4-Will PXE may introduce some trouble i can't think of now ?
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.
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'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 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 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 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.
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.
View 2 Replies View RelatedI'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.

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?
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).
View 1 Replies View RelatedSo 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.

View 2 Replies View RelatedI 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.

I upgraded to F13 this week. And autologin just sits with autologin present, but I have to click the autologin (rather than a user name) and then click again to actually login. That's not so "auto" anymore if I can't push the power button and come back in x minutes with everything and running.
I had this in my /etc/gdm/custom.conf
TimedLoginEnable=true
TimedLogin=marty
TimedLoginDelay=8
What changed and what do I need to do now to get autologin to get off it's ass and log me in?

I am using Ubuntu 10.04 64-bit and I purchased a new ALFA AWUS036H wireless card. I would like to know if this "1Watt" wireless card is configured for full power. iwlist wlan0 txpower results:
wlan0 unknown transmit-power information. Current Tx-Power=27 dBm (501 mW). It appears to me that I should be able to increase the power. "iwpriv wlan0 highpower 1" does not work. Do I need to patch the new default driver that comes with Ubuntu 10.04 64-bit with the aircrack one following these directions:[URL]...?

I'm looking for any power monitoring devices for Linux to allow monitoring power quality, voltage changes, and outages. This would be for North American three phase power system.
