• How can I disable usb-autosuspend for a specific device?

  - by black_puppydog

  This is related to the issue discussed in this question. Summary: the mouse freezes when operating on battery since it is autosuspended after a certain time and needs more time to wake up. Disabling usb-autosuspend for the mouse's receiver in powertop is a temporary solution but does not survive a reboot. How can I permanently disable the usb autosuspend for only one specific device? A solution that does not involve installing additional packages is preferred (after all, I want to disable something) but not required. Removing powertop (which seems to be a solution for some) is not what I want - I like poertop... And installing laptop-mode-tools to disable usb_autosuspend alltogether is not what I want, either, thus the new question. Also: will this affect the battery of my notebook? The logitech unifying receiver for the mouse stays connected all the time, so if that prevents the autosuspend from happening for all devices that would probably be bad.

• Why does waking from hibernate take nearly ten minutes on 11.10?

  - by Shane O'Connor

  Im running 11.10 64bit on a Dell XPS 15 L502x laptop. It uses an i5 proc and has 16Gb ram. Whenever I close the lid on the laptop I have it set to hibernate as I want to continue whatever I was previously running. Generally that is simple text editing, so my mem usage would normally be only a Gb or 2. When I open the lid and it resumes from Hibernation, it takes up to ten minutes to do so. Extremely frustrating. Is there anything I can do to make hibernate function properly. On windows it used to wake from Hibernation in less than 30 seconds. Its really frustrating and souring my experience with Ubuntu. Any help would be gratefully appreciated! Thanks guys/gals! S

• laptop-mode-tools and harddrive spinoff

  - by sagarchalise

  So I wanted to extend my laptop battery life. After googleing a lot I found many tips and tricks. Some even in this site as well. Then I found this package in synaptic as well laptop-mode-tools. Now I am not well aware of what harddrive spinoffs are, so I have a dilemma of installing this package as it seems to remove acpi support as well. So my question is, how reliable is this package in battery life extension and what configurations should I use with it ? Also I stumbled upon some posts saying spinoffs may kill the harddrive as well. So can anyone clearify with some configuration tips especially for laptop-mode-tools. Thanks in advance

• My computer will no longer suspend or shut off when I close the lid

  - by dave

  This is somewhat annoying. I have an old laptop and the screen on it is shot, so now I have an old monitor hooked up and it works fine. Before the upgrade I had it set so that when i closed the lid on the laptop everything would shutdown or suspend, when I lift the lid, everything would come back. Now, however, when i close the lid nothing happens, when i open the lid the screen flashes black and comes back. I have it set so that it should suspend when i close the lid. It's confusing...

• USB blocks suspend on a Gigabyte GA-890GPA-UD3H with ATI SB700/SB800

  Following on from question 12397, I'd still like to get suspend working on my Phenom II X6 / GA-890GPA desktop machine running current Maverick.

• Has the Ubuntu heating problem for Sony Vaio users been solved?

  - by nischayn22

  I use Sony Vaio VPCEA23en with graphics card ATI Radeon HD 5145 and have been using Ubuntu 11.10 and recently upgraded to 12.04 beta, however the problem of overheating (60-70) still persists. I have installed the graphics driver properly. Are there some features of Ubuntu that cause this problem? I would have no problem uninstalling them; Or will using a lighter version of Ubuntu (lubuntu) solve this problem? Right now I am using Win7 and would like to switch to Ubuntu ASAP.

• Battery charging is flickering [closed]

  - by Michael

  A few days ago my notebook started to bug around with charging the battery. When the battery is not absent notebook runs smoothly. Until I plug in the battery. Then it starts to charge but immediately stops and restarts charging and stops and so on. If the notebook is not running battery seems to charge well (LED is not blinking). And LED is not blinking intermittently. Seems to be arbitrary. Does it have something to do with that? This happens every second. [13354.078696] keyboard: can't emulate rawmode for keycode 240

• How to prevent my screen from either dimming or the screen-lock starting when watching YouTube?

  - by Steven Roose

  My screen brightness used to dim after a few seconds to preserve battery. This is default in Ubuntu 12.04. However when watching video it should not dim. This works correctly when I watch videos using native applications like VLC. With in-browser video, however, the screen is not prevented from dimming. This is very annoying as you have to move your cursor every 10 seconds or so. I used to use Mac OSX where I had the same dimming settings and Flash videos were taken into account correctly. Anyone an idea how you can make YouTube prevent your screen from dimming?

• Why does my fan run so hard on my Dell XPS 15z?

  - by Kilhoffer

  I recently bought a Dell XPS 15z. It came with Windows 7 Home Premium, but I really wanted to try out Ubuntu on it. I ran the Windows installer and was surprised how smooth the process was. Within 10 minutes, I had a dual boot setup with Ubuntu 11.10. It boots into Ubuntu just fine and everything seems to work. I've read a lot about problems with touchpad and wireless, but honestly, I've had none of those issues. The only thing that's really bothering me is the fan constantly runs fast. Under Windows, it rarely ever came on and when it did, it wasnt spinning that fast. What could be going on under Ubuntu that would cause this? I want to get that under control because I want to use Ubuntu as my primary OS and screw Windows. Any help would be much appreciated! Note: I've read that others have set acpi=false, but I have not made any changes to the default installation. Should I make that change?

• How do I detect when my system wakes up from suspend via DBus or similar in a python app?

  - by con-f-use

  In a background Python script I need to detect, when the system just woke up from suspend. What is a good way that does not rely on a root script but rather on python modules such as DBus? I'm new to dbus so I could really use some example code. From what I read it's related to org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.Resuming Can anyone help me out with some code that connects the resuming signal to callback?

• Hibernation is still missing from menu in 13.10 after enabling via polkit. How to enable?

  - by LiveWireBT

  I know that since 12.04, we need to add a policykit rule to enable hibernation (see question How to enable hibernation? and the Official Documentation). I can successfully bring my laptop into hibernation mode with sudo pm-hibernate or sudo s2disk, so the rule is in place and works, but the hibernation entry is still missing in the menu. I can tell from looking through the source of the indicator-session package (but not understanding the whole code) that there is still a hibernation menu entry in the code and it should be displayed when the system is capable of hibernating. Please calm down if you're enraged by this. This is very unlikely to be a conspiracy, but rather a bug/regression on a deeper level, which can happen when you move code around or replace it. Question: What needs to be done in 13.10 to properly tell indicator-session that the system can hibernate? Possible duplicate: Hibernation still not available - No activity, because saucy was in development at that time, so out of scope for AskUbuntu. Related bug report: https://bugs.launchpad.net/ubuntu/+source/indicator-session/+bug/1232814

• What are some good examples of Powernap scripts and its use?

  I would like to use powernap for putting my media server into suspend mode, and I haven't been able to find any example /etc/powernap/action scripts out there, except these: one two three Does anybody have a good script or recommend particular techniques with its use? From the comments of the default /etc/powernap/action script: # You may do one of: # 1) Write your own custom script below and make this file executable, # calling some specific action, such as: # /usr/sbin/pm-suspend # /usr/sbin/pm-hibernate # /sbin/poweroff # echo 'I am wasting electricity' | mail [email protected] # 2) Replace this file with an executable script or binary # 3) Symlink this file to some other executable script or binary

• How to enable hibernate on Ubuntu 13.10?

  - by mjwittering

  Something I usually do after installing Ubuntu is reactivate the hibernation function. I find it quite useful to function for the more energy concious. Typically, I'd complete the instructions in this tutorial for Ubuntu 12.04 and I'd be back in business. However, it does seem to work any more.

• ACPI 30k+ interrupts per second

  - by ultimatebuster

  My computer is currently doing something like 30k+ interrupts per second. This causes battery issues as well as the CPU being always stuck at the highest speed, making it very hot (overheating.. 75C at IDLE) Powertop info: 99.4% (32052.4) [acpi] <interrupt> 0.3% (115.9) [iwlagn] <interrupt> Just to clarify this started suddenly a couple of days ago. It didn't have this issue before (though I had a tonne of headaches with Linux on my computer in general..)

• How do I add pcie_aspm=force to my boot options?

  - by nargo7

  I just upgraded to 11.10 from 11.04 on my laptop (I don't have Windows) by downloading from the Ubuntu website. The laptop battery is in bad condition, but I was using it with the 11.04 plugged to AC all the time, and everything was fine. After installing 11.10, the laptop seems to not notice that it is connected to AC, so it shuts down a few minutes after starting. I read that I have to type pcie_aspm=force in the boot command, so I tried accessing it by pressing the "F6" key while booting, and then the other F keys, but nothing happened. I also found that I can write that instruction in the terminal window, but I don't know in which file or location. I would appreciate some help, but I am not a computer engineer, so please write the instructions in plain English.

• How to change keyboard sleep button to hibernate?

  - by Allu2

  I have a keyboard with a "sleep" button that does indeed make my computer go to sleep. The problem is that Ubuntu can't really handle sleep on my computer, causing it go into a non-responsive mode, having the CPU fan spinning at full speed and it stops receiving any input. Hibernation instead works mainly as it should. I would like to set the sleep key to hibernate, but the keyboard settings' hotkeys tab doesn't have this "sleep" keybinding and though I could make new one with hibernate --force as the command, it would require root rights to run. How can I change the keyboard sleep button action to hibernate?

• Shut down Netbook by closing lid - ubunti 13.10

  - by The Liquidator

  My wife has an Acer Aspire One (with the SSD Card and an SD expansion card). It has never been able to hibernate or suspend, always creating errors and occasionally trashing the data on the SD card, which is the home partition so it's unfortunate. To get around the problem I have set all exit methods to produce shutdown - she tends to simply shut the lid. I'm aware the default behaviour has for some time been to suspend, but I've got round that using the gnome tweak tool. However, I've just installed 13.10 and whilst I have installed the gnome tweak tool and set it to shut down the system appears to be ignoring/bypassing the setting, electing to suspend when the lid is shut. Can anyone tell me how to fix it please? I'm quite happy to get my hands dirty with the command line.

• Cannot resume from hibernate (s2disk)

  - by hwjp

  I seem to be able to hibernate OK using s2disk, but when I switch the laptop back on, it seems to hang half-way through the "resuming" menu. The splash screen looks healthy, it seems to be trying to resume from the correct disk, but it hangs about half-way through, with three little pips. One great help would be - where can I find the logs, and how do I get more verbose ones? There is some info in /var/log/pm-suspend.log, but that all seems fine, just lots of hibernate: success messages... How do I switch on more verbose logging in s2disk? And what about the resume process, where are the logs for that, and how can I make them more detailed? Background: the standard Ubuntu hibernate wouldn't work, so I've install uswusp and its associated tools - s2disk etc. That initially made things worse, but a fair amount of fiddling with its config, my swap size and so on seem to have got it at least seemingly successfully suspending...

• xubuntu 12.04 restarts after suspend - only from my account

  - by Yoav Aner

  After installing a clean xubuntu 12.04 I noticed that when I suspend, the computer suspends and turns itself off (you see the lights go off, and a click sound from the HD or fans), but then about 2 seconds later it turns itself back on again... The odd thing is that: It doesn't happen when booting from the liveCD I created another user account. When I log onto this account I can suspend fine. The computer stays off until I press the ON button When I remove my .config folder and it's clean - I can also suspend without problem on my account So it seems that something in my user config is causing this, but I can't work out what it might be. I tried diffing the two .config folders, and also all processes running with one account compared to the other (ps -ef |grep <username>), but couldn't find anything obvious that might be causing this...

• Set Idle Time in Ubuntu 12.04 Server

  - by ssanj

  I recently installed Ubuntu 12.04 Server and am looking for away for get the server to suspend after an idle time. When using the desktop version I could use the Gnome powersaving tool to specify the idle time. As I have no GUI on the server is there a way to set the server idle time via the commandline/config file? I will send the server a wake-on-lan packet to wake it up, if it is suspended and I need to use it.

• How to improve battery life on a HP Pavilion dv6?

  - by user1793249

  I apologise if this question is too similar to the numerous others already asked, but I'm a beginner and I really need your help. So...I've installed Ubuntu 12.10 a few days ago and I have only been able to get up to one hour of battery life. When running Windows 7 I get up to 3-4 hours. My screen is ultra bright, even tough the screen brightness is set to the minimum (I installed xcalib to dim my screen, but it doesn't improve the battery life) I read about Jupiter and installed it, but it doesn't have a noticeable effect. Thanks for your time.
