Ubuntu :: Power Management Shutdown / When Suspend Button Is Pressed?
Jun 25, 2010
I have a dell zino inspiron media pc with Ubuntu 10.04 installed. I am able to shutdown using the power button on machine i.e. System->Preferences->Power Management option 'when power button is pressed': choose 'Shutdown'.But for option 'when suspend button is pressed', I only get 'Suspend' or 'Hibernate' in the drop-down. Where is my 'Shutdown' option?I really want to be able to shutdown my machine from my wireless keyboard!

I am currently using a Ubuntu Netbook Remix 9.04
When I press the power button, I see a dialogue box which asks for confirmation and if nothing is confirmed system automatically shuts down in 60 seconds.
I want to change this time of 60 seconds to say 30 seconds. Is it possible? Also is there a way to hide that dialogue box...

A friend of mine has an old emachines with XP on it and at first it would complain it had to test the disk and turn off in less then a minute. Now it won't do anything except run the power supply and cpu fans while the start button is pressed. I checked for power on the blue , purple ,red and orange wires while 14 and 15 were jumped on the power supply. There are no lEDs on the board and no beeps. I disconnected all the peripherals also

What happened to the "Do nothing" option for "When the suspend button is pressed" in Lynx? It would also be useful to have a "Do nothing" option for "When the power button is pressed".

technically, this is UNR with lxde installed after extended UNR use. i like being able to hit my power button in gnome, and getting a message asking what you want to do, or cancel if needed. well, in lxde, the shutdown button brings up a similar message. could i map the power button to show that popup in lxde?

I have a Genius K627 Keyboard with Power, Sleep and Wake buttons. ACPI is unsupported on my computer, but it can turn off its power supply when the system halts (PM is ok). I would like to bind the Power key on the keyboard to execute the /sbin/halt command. What I already know is that I can specify an event in inittab (kbrequest) that would execute a command. What I don't know how I can make my system receive pressing Power button as a kbrequest. The scancodes of Power button on the keyboard (by showkey): 0x74 0xf4
This is the line I was talking about in my inittab:
Code:
ce:12345:kbrequest:/sbin/halt
I think I should edit /etc/console/boottime.kmap.gz but don't know how I could insert this scancode into it.

I have Ubuntu 10.10 on e-machine T-1221 I can shut down the machine using :
sudo shutdown -h from terminal
I can shutdown using powerbutton on case. I can't use the applet indicator powerbutton in root account, but, I can use the command under "System-->-Shutdown" in root account, but I don't see "System-->-Shutdown" in users account. Is there a way to add it ? I installed Debian 6.0 Squeeze on my Acer Aspire 3620 Laptop it works just fine and has the same Gnome Desktop. The only thing different is that there is no powerbutton available thru Gnome applets, only the command on menu under" Sytem-->-Shutdown", which I'm fine with on this machine.
These are the things I tried on emachine T-1221
I tried "acpi=force"
I tried "noacpi"
I tried "noacpi nolapic"
I read the bug reports it stated that on live-cd there was only suspend and hibernate. There is no shutdown or reboot. I tried: "#start acpi", it closed with errors. It said that Ubuntu uses upstart. Is there a script which you can add to power button to add the shutdown.? Really I don't necessarily need powerbutton, I think the work around would be adding the command to "System-->-Menu.

When I boot, apparently any Linux (Ubuntu and CloneZilla), I see the letters Code: ^]]B scroll pass, over and over again. This represents the down key as when I try to do anything the down key is held down. This occurs during boot on Ubuntu (once I get to the login screen it stops and does not happen). This does not happen at the GRUB screen or in Windows. It also occurs during the entire CloneZilla process and Ubuntu alternative install process (making both of these impossible)
I can't find any reason for this to happen and have been using both CloneZilla and Ubuntu for a long time before this happened. Does anyone know what I could try to fix this.
Ubuntu no longer boots.

I'm learning Signals, and I have a question:
Is possible to make a handle when I press any of the keyboard buttons?
The SIGINT handles the Ctrl-C combination, but I want to handle if any keyboard button was pressed.

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 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 have a Microsoft Wireless Desktop 3000 (Wireless Keyboard 3000 + Wireless Mouse 5000), actually, I have two of them, one in this computer, running Ubuntu 10.10 and another one in a box running Ubuntu 10.04.In the box running 10.04 I can perfectly use 70% of the hotkeys the keyboard has, the 30% left I guess they're not compatible, but that's not a problem.In the one running 10.10 whenever I use a hotkey,t works, but,sametimet "blocks" the mouse left button in the 'pressed' state. Let me be more clear, it's like I'm holding down the left click all the time and I don't ever release it. Unless I restart the system, I can't recover the left click.

Alright this is not a huge issue but a rather annoying one. I hook my laptop up to my lcd to watch movies all of the time. The problem is though I have selected and reselected many times for the screen to not power off after so many minutes of inactivity. But for some reason it doesnt work. If i set it to an 1 it still like every 5 minutes turns off my screen. Im running 9.10 on a toshiba satellite with an intel graphics card.

I have a laptop with 10.04 installed. When it is plugged in with AC Power, the screen fades black after a few minutes and locks up after about 10 minutes (shows a dialog for passwd when back).This gets really annoying when listening a movie or just reading text.System->Preferences->Power Management is set to "never" for everything.gconf-editor->apps->gnome-power-management is set to "0" for everything finishing with *_ac.

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.

I just did a fresh installation of Kubuntu 10.10 on a laptop last night, which has a 1.6GHz Intel Core Duo CPU.
I was very disappointed to find that there appears to be no way to configure CPU frequency scaling in the System Settings. There were options for this in 10.04.
I prefer to have the CPU running at maximum speed when running on A/C. In Maverick, however, I have had to resort to installing cpufreq-utils, and setting the CPU cores to 'performance' from the command line.
I like this laptop a lot, but even many simple games run sluggishly if the CPU cores are not set to run at max GHz. (As a matter of fact, this machine is much more sluggish even with CPU cores running at maximum in 10.10 than was the case in 10.04.)
I wonder why such an important option would have been removed from the power management settings?

Ok, I am running a file server that can be accessed throughout the house. I was able to successfully wake from suspend and it works beautifully. Now what I need the computer to do is go to sleep after lets say 30 minutes of inactivity so that I never have to touch the computer and it will use minimal power until I need it.
Anyhow, I tried to set the settings in Power management and the only thing that happens is the display turns off. the suspend on the desktop works fine, I can type in sudo pm-suspend and that works fine. but the computer just wont go to suspend automatically by way of the power manager.
I have tried changing the /etc/pm/config.d/00sleep_module to say SLEEP_MODULE="uswsusp", but that only made the computer go into some crazy linux mode that I had to reboot from. I had to change SLEEP_MODULE="kernel" (actually, I left it blank as it is the default).
I also turned off my screensaver so there wouldn't be any confusion from that.
I also ran cat /var/log/pm-powersave.log and I got a long list with the following being one of the main texts that kept repeating. "/usr/lib/pm-utils/power.d/sched-powersave false:**sched policy powersave OFF"

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

when I boot up ubuntu, the suspend and hibernate buttons will be missing and the alsa stuff wont work. When I select shutdown or restart or log out from the power menu ( the one that's missing the 2
buttons) it only logs off the user. I've tried reinstalling the kernel and updating grub for a solution to no avail. The only way to shutdown the system when this occurs is through a sudo halt command in terminal. I may have to use the command a few times until the computer will boot with sound and all of the suspend/hibernate buttons in place.

I am having some serious speed/connection issues with my laptop's WiFi card, and it has been suggested to me to disable power management for it, just as an experiment. However, when I run "sudo iwconfig wlan2 power off," I receive the error:
"Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlan2 ; Operation not permitted."

I've recently installed Ubuntu 10.04 and found the following problem: power management doesn't appear to be working. If I'm away from my computer for only a few moments, the screen is on dim when I return and I have to log on again. I've set the following states in Power Management: NEVER SWITCH OFF SCREEN and haven't ticked the DIM WHEN IDLE BOX. Can anyone help with this problem - it's infuriating. Meanwhile, I've gone back to Ubuntu 9.10 ...

I did a live upgrade from 11.3 KDE and observe a following issue.When I press the shutdown button on the laptop it initiates the shutdown and shuts down fine but after a significant delay of time (something like 30 seconds). When I click the shutdown button in KDE it initiates the shutdown instantly. This was not the case in 11.3 where the shutdown worked the same regardless of the method that triggered it

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.
