Ubuntu :: 10.10 Clean Install - Sudden Shutdown / Power Off
Nov 9, 2010
I just did a clean reinstall of Ubuntu (10.04 --> 10.10). After the install, any time I do CPU intensive work, my PC is suddenly shutting down like it's overheating. Everything was working fine for months, and started having problems immediately after the reinstall. so this is not a problem with my hardware, and it's not a problem with my fans needing cleaning -- it's a problem with software. So please don't tell me "that sounds like overheating, clean your fans". Something is different in software-land between 10.04 and 10.10 that is causing this to happen.
I have checked my log files, and can't find anything related to overheating -- searches for things related to lm_sensors, "temp", and "thermal" are not turning up anything in the system logs (syslog, kern.log, or messages). I also looked at the logs around the times of the sudden shutdown, and couldn't find anything unusual. How can I diagnose this? I'd like to file a bug report, but since I can't find anything in the logs, I honestly have no idea how to go about providing useful information. Is there anything besides overheating that might be causing my laptop to suddenly shut off? (I am using a Gateway M-6888u laptop, btw)

I have an user space application that performs file I/O operations, when a SIGKILL is captured, some routines are done first to ensure that all I/O operations are completed before rebooting the application or system. My question is, this won't work if the power button is pressed or the power supply is disconnected, so there can be incomplete I/O operation or corrupted data written into the file, so is there a way to prevent data corruption or at least complete any ongoing operation when this scenario happens? Assuming there is at most 1 second before the power really went out, can I/O be still completed?' I'm running the application on a busybox 2.6.14 kernel on an embedded system board.

Did a clean minimal install of Testing in a Virtual Machine (VirtualBox).Login as root.Type "shutdown now".It starts shutting down, then says INIT: Sending processes the TERM signal Give root password for maintenance (or type Control-D to continue):If i press Control-D it goes back to a login prompt.Okay, i maybe missing a point since "shutdown -h now" gives the expected behaviour.Call me old fashioned but I think that a "shutdown now" should shutdown a system, and not effectively reboot the system. There is a reboot command for that.

I run Ubuntu 10.04 on a HP dv2000 laptop with 2GB RAM. I see a strange problem with my system. When running on battery and the level hits about 43% (+- 1%), the system shuts down suddenly. No warning and no information in logs either. Temperature of both cores are below 50 C. I have tried cleaning the dust withing the laptop chasis but no progress.
I have done quite some research on this and other forums but haven't found anybody else with similar problem.

for some reason, my opensuse 11.2 can not shut down as normal. by pressing ctrl-alt-F1 and issuing "init 0", the console displays the following messages and then stops there. Segmentation fault Master Resource control: runlevel 0 has been reached skipped services in runlevel 0: SuSEfirewall2_setup I have to push power button to shut down it.

Offlate I installed F11 i586 on my laptop. F11 shares the hard disk with Vista Home Premium 32-bit. The problem is that when running F11 (or even Ubuntu), my system shut off suddenly(not a normal OS shut down, but a sudden power off without any warning). This could have been a hardware trouble(heating) but it doesn't happen with Vista.
Machine specifications:
Maker: Toshiba
Model: Satellite L305D-S5881
AMD Turion X2 Dual Core Mobile Processor RM-70
3072 MB 800 MHz SDRAM
I don't want to open up my machine unnecessarily, if it isn't a hardware issue.
I am not sure how to verify the bit length of the machine and the OS and does it create a compatibility issue ?
Your advise would be highly appreciated.

I have been using this tip at URL.. to delete the temporary files created in /tmp for quite a few Fedora versions. But, I just found out that it does not work in F12. Is there are reason why it doesn't work?
You can put this into /etc/rc.d/init.d/syslog into the "stop)" section. This will clean up /tmp at every shutdown and keep your disk clean. Please note that you should not run this command when X-Windows is running.

I have a file server that has a raid array with a jfs file system attached. Whenever there is a power cut (quite frequently in our house), and the server is not shutdown cleanly, then the raid array is not automatically mounted since ubuntu doesn't know if the journal is clean. I have to then manually run fsck and remount the partition by hand which is a bit annoying. Basically, does anybody know if fsck can be setto run if a non-clean shutdown has been detected, or failing that, on every boot?

I've been having a bad problem with X freezing up (but not the whole system), and I hate continually performing unclean shutdowns with the power button.Will an Alt+SysRq+o shut down the system in a way that doesn't cause the loss of disk buffers? Obviously, whatever hasn't been saved to the buffer will be lost, but my concern extends to the buffers themselves.ext4 and autofsck make this less of an issue, but I hate the thought of unnecessary silent corruption until the freezing stops.

I configured cron to clean my /tmp directory, should I also add other locations to clean and especially /var/tmp.

I've been using Ubuntu on and off since 8.04, but only last week decided to make a real switch across to it.After installing 9.10 64bit though, my laptop while running Ubuntu just turns itself off at completely random times - it doesn't seem to go through any shut down procedure or anything, it's more like the power's just suddenly cut. It sometimes happens 5 minutes after being turned on, or sometimes 4 or 5 hours, it really is random.I really have no idea where to even begin trying to stop this. I think it must be a software thing because this has never happened with windows or earlier versions of Ubuntu, but other than that I don't know what to do to stop this.I'm dual booting Windows 7 32bit and Ubuntu 9.10 64bit, and this is on a Toshiba L350-D 11-D laptop, which has a 64bit AMD processor.

I found an application AUTO POWER ON & SHUTDOWN in windows which is really very useful to those who have night unlimited broadband connection. I searched for similar application in UBUNTU as I am slowly shifting to UBUNTU from 10.04 (maveric) version. Whenever I search for application or for other options, so many have written failed attempts only.

I have a PCChips M830 version 5 motherboard with AMD Duron 666mhz cpu and 786mb DDR ram. I installed Mythdora 12.23 for playing videos on my tv and music on my stereo. Eventually I hope to get DSL out in the sticks where I live and can then stream movies from Netflix. I did not install MythTV. The installation went fine and I had no errors. I've done a lot getting it ready and it is stable. The problem I'm having is it will not power down. When I click "Shut Down" and then press F1 I can see the shutdown procedure and all looks fine until it gets to "Power Down".
At which time it freezes and I have to flip the power switch on the power supply for it to power down. If I open a terminal and do "su root" and use "shutdown -h now" it exhibits the same behaviour. I've looked through the bios settings several times paying close attention to the "Power Management" section and have not seen anything relating to this. Doesn't seem like a big problem I know, but it keeps me from booting the machine from LAN since the ethernet card WOL settings are lost when powering down with the power supply switch.

I would like a program that will auto shutdown my Linux machine when it detects low power or X amount of minutes remaining on UPS. I don't have NIC's in my UPS's so that's why I am asking... Not even sure it is possible for the Linux machine to detect when it switches to AUX power.

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 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...

After a recent upgrade, the red power icon in the far right of the upper panel disappeared. In its place is a half obscured copy of my user name, which appears right next to my user name (along with the chat icon). The chat icon/user name is functional, as it is supposed to be, but the half obscured user name that replaced my shutdown/restart power icon is just a bug, and has no function. Not only is it unsightly, but I miss the power icon. Yes, I can right-click on the panel and add one, but it doesn't allow me to drag it all the way to the far upper-right corner, where it is supposed to be located... I found this post in another thread: sudo apt-get install indicator-applet-session, but it did nothing to solve my problem.. I'm running 64-bit 10.10, btw, if that makes any difference.

This OS is has been cloned from the drive of another computer. The motherboard is now an SIS730. I assume the hardware is sufficiently different to prevent the OS from shutting down the computer.How do I fix this? ---without installing, if possible.

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 built a Centos 5.3 server for a friend of mine that is being used as a NAS server. The server has 4 1TB drives in a RAID 5 configuration and a dedicated non raid system drive for the OS. My friend isnt very Linux literate so I need this bow to be relatively simple. I have worked most of it out but have a question with regards to remote reboot.
I need to be able to shut this device down through the power switch without human intervention (at the moment when the power switch is pushed the server asks to confirm shutdown) the server wont have a Monitor connected so this isn't practical. Is it possible to use the power switch to do an clean, immediate shutdown?
The other option is shutdown through a web page is this something that has been done before? I know he can do it through terminal by issuing a shutdown now command but as I said this guy wants something simple. I don't really want to explain everytime he needs to shut the Server down how to do it if he can just do it via a website or even with the power button.

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.

I have machine which I am using a server for all my office activities. We have fedora (11.0) installed in that system. When even power goes out system is getting shut-down abruptly. We have UPS for this system and some times UPS also runs out of power. Do we have any software, which monitors battery power and shutdown the system gracefully, when system knows that power is running out. I am using desktop machine, not a laptop. So I may some hardware like battery which runs fot sometime, even though there is no power. Then there will software which monitors and shut down the system gracfully.

I have upgraded my netbook system to lenny. I got almost every thing working right except gnome-power-manager shutdown event. It shows critical battery level (red color) on its applet on the panel but it does not do the normal safe shutdown action. Instead, it just do a sudden shutdown of the system which causes the lose of some data. Is there any way to solve this issue using lenny's current version (2.22.1-4)?My netbook is AcerOne.

I have problems with my acer aspire M1201. I have added a 2GB RAM beside the 1GB stock RAM. Currently I have reformatted my stock Hitachi HDD 160GB and I have added another HDD in which it is a Samsung 500GB HDD SATA drive. I have successfully installed GNU/Linux Opensuse 11.2 OS in the new harddrive (Samsung). Besides all that, the other specifications are all stock. After 2 days of successful runs in the new OS and no problems at all, the OS hangs and fails to boot and displays this, Error 18 : Selected cylinder exceeds maximum supported by BIOS. I should mention also that while setting screensaver, when I chose OpenGL, the OS hangs and i have to hard-reset my pc. I suspect that the current BIOS version which is R03-B1 and product name ACRA8000-S03-990610-R03-B1 needed update due to new hardware. But currently there is no new downloads in Acer's website regarding my BIOS version. What should I do to run my Linux successfully? I should also mention that I haven't logged to the internet due to unsuccessful dialer which i have consulted my internet service provider and yet to rectify.

I have an old machine running Ubuntu 9.10 and XP.t is a P4 and Nvidia FX5200 card.Yesterday all of a sudden the screen started flashing black, the same type as when you install new graphics drivers and the resolution is changing. Only here it keeps happening over and over, the mouse isn't usable fully, the icons and menus are distorted, and I basically can't do anything.
I ended up reinstalling 9.10 and everything was working fine until I installed EnvyNG to get my nVidia drivers. It required a restart, and once I logged in the same thing started happening. So I said screw this, and installed 8.04. Yet even in 8.04, once I used EnvyNG to install the drivers, the same thing happened.A few other detailsP works fine, although one time a similar thing happened on XP (not as bad), and was fixed with a reboot.- This PC runs through a KVM switch, but I connected it directly and the same thing happens.I've found no help via Google. Sounds like a possible hardware problem, but it seems to work fine in XP and only acts up in Ubuntu once I install drivers.
