General :: How To Disable Automatic Power-off
Feb 24, 2011
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)?

ubuntu 10.04. My computer is left on all the time. My computer's screensaver comes on 10 minutes after last keystroke. Which is fine. However, when I return to use the computer and disengage the screensaver, ubuntu ALWAYS requires my password to continue. How do I stop ubuntu from asking me my password everytime I wake my computer up?

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?

My laptop running Ubuntu 10.04 insists on automatically logging me in without asking for my password. The only thing is, I've disabled auto login and it shouldn't be doing that.
When I first boot up Ubuntu all I have to do is select my username, no password required to log in. I want the login screen to prompt me for my password for better security.
Here are the settings I already have:
System - Administration - Login screenSet to "show the screen for choosing who will log in"
System - Administration - Users and GroupsI am the only user I have an Administrator level account "Don't ask for password on login" is unchecked, i.e. it should ask for my password on login. If I create a new user with the same settings, that user gets asked for its password. But I don't.
Surely this should be enough to disable automatic login.

I have enabled automatic login in Lubuntu, and have now added a second user, I want to DISABLE the automatic login, or perhaps change the default login. The usual Ubuntu admin window for this does not appear to be available. Where in the conf files this setting is, and or whether there is a GUI that controls this.

From the GUI, there is an option in the network settings "Automatically obtain DNS information from provider", just wondering how do we set or disable the same option through the command line, which files do we have to modify?

Update: Solution posted below. Distro: Kubuntu 10.04 AMD 64. My system automatically mounts USB devices when attached to the system. I have explicitly disabled this function in (KDE) System Settings --> Advanced --> Removable devices. It doesn't matter - as soon as a USB device is plugged in the system mounts it as root.

I've just installed Ubuntu 10.04 desktop. I've created two user accounts, one for admin purposes and the other for standard users. At boot up, I have the option to pick one of the created accounts or select "automatic login." When I select automatic login, it logs me into the admin account. I've double checked that the "don't ask for password" option is not selected on either account.
The only thing unusual that I did was select the "don't ask for password" option during the install, and then later (after the install was complete) decided that's not what I wanted and unchecked it.
I need to accomplish one of two things. Either change it so the auto login applies to the standard user account, or remove the auto login option from the login screen altogether.

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?

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.

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'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 disable display power management.
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 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 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 use Squeeze with Xfce. My problem is that recently (after the xfce updates) the xfce power manager doesnt react to the power button - it is set to suspend. I dont have gnome-power manager or anything like it running.
If i reboot the computer, the power button will work but if i suspend and resume, it doesnt work again.
The computer is built on an Asus M3N78-VM mobo (2GB RAM/Athlon3200+ single core).
acpi_listen detects the button press.
Any thoughts?

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]...? Monitor mode and a injection tests seem to work fine with the driver I have installed.

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. I want to have this data fed live to my own program. It should be something much better than just jury-rigging a circuit to fee the power waveform into 2 or 3 audio cards.

I had unplugged my PC last night as sometimes there's storms at night this morning I plugged in PC and the power light is blinking and the PC wont come on at all tried different power cord, same result
PC is a AMD athlon64 3300+ 2.4ghz SiS graphics
probably the power-supply or what?
If it is the power supply, how do I find new one as I've never had to replace anything on it or any other PC?
Also, I really need access to the hard drive but it's a weird hard drive and was wondering if I could put that hard drive in my K7 PC, which already has 2 drives in it can a pc have 3 drives? do I have to add/have another ribbon cable for 3rd drive?

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.
