Ubuntu :: Computer Starts Then Shuts Down All By Itself?
Oct 3, 2010
After using Ubuntu 10.4 for months, my computer has started turning itself on without my pressing the on button. Sometimes it gets halfway through the boot process and shuts itself down. Sometimes it gets all the way to the desktop and a window pops up saying shutdown in 60 seconds however it never waits but shuts down immediately. Probably the second time this happened, I had time enough to get to the Power Manager and made sure it was set to 'never' power down. Currently the on/off cycling is happening so quickly I can't check the BIOS or grup. My only control is the master power switch on the back

I know that this is a know issue with nvidia cards and that is (of course) what I have. I have tried many of the fixes that I found on these forums. Some of them seemed to work but the problem has still remained (maybe its because i'm still too new)
I have been tempted to go back to windows but I cannot let this problem drive me away from ubuntu

I've installed 10.10 on my Asus 1015PE and when I went to look at the partition table I couldn't get Gparted to stay open. When I click on it, it opens the window, says that it is searching then scanning, then the window and program closes. The window is up for maybe 3 seconds tops.
I've got two other ubuntu netbook versions running on the same machine and gparted works fine on those installs. I've tried completely removing gparted and reinstalling, I've rebooted, I've tried calling it from the terminal, but always the same: it opens, starts to scan and closes.

I installed ubuntu 10 yesterday and I have a real frustrating problem. It shuts down for no reason at all, at first I thought it was because I was not using it (power management or maybe because of the screensaver) so configured it to never put it to sleep or shut down, and disabled the screensaver but it keeps happening. This is actually the second time I'm writing this post, because it suddenly shut down again while I was writing this before submitting it. I used to never have this problem before when I was using windows, so the problem must be something with Ubuntu.
Could it be something with my gfx driver? I tried configuring Fluxbox to use my second screen as an extended desktop but couldn't get it to work except with Gnome. If I do "fglrxinfo" I get a segmentation fault, so I messed that up but I'm okay with that because everything is working like I want it with Gnome. One weird thing I've noticed is that ubuntu once said (when booting) that it couldn't find /dev/null...? Should I just try a reinstall? I'm on a quad core with 2GB ram and an ATI HD 4870 2gb graphics card.

I've been using Ubuntu for about one year. Recently upgraded to 10.04. The PC tries to boot, comes to the "Booting from device hd..." screen and then shuts down. It shuts down or halts but doesn't power off. The CPU is still powered. This happens for about 2 in 4 boots. The recovery mode runs just fine. It says no damaged partitions. Only the 'booting from device' is the problem point.

I upgraded to 10.04 and it is sooooo annoying. The computer will just randomly shut off. Sometimes it will be 10 minutes after turning the computer on, sometimes 10 hours!

Sometimes, when I leave my Ubuntu's X Server on, I'll come back after several minutes and see that my machine is powered off. Sometimes this happens, sometimes it doesn't, but I don't think it's because of hardware failure rather than my lack of measurement.
It used to power off in terminal mode (CTRL+ALT+F1) but then I added this to ~/.bashrc and it went away:
Code:
if [ "${USER}" == "root" ]
then
export TMOUT = 3600
fi
Also, I checked my logs and I see this:
Code:
Feb 2 00:00:09 l1nux AptDaemon: INFO: Quiting due to inactivity
Feb 2 00:00:09 l1nux AptDaemon: INFO: Shutdown was requested
Since it's not a CRITICAL message, but an INFO, it seems like its a planned shutdown.
Does anyone know how I can turn this feature off?

Since when I installed Squeeze I'm having this problem. You know how disturbing it is. I don't know if this is related in any way, but when I play music or watch video and do other things at the same time it looks like this happens more.

My computer randomly shuts off sometimes and I'm not sure what causes it. It doesn't always happen when I'm doing the same thing.I know this is hardly any info, but if someone could let me know where I can go to find logs and Also, if this means anything, to restart my computer I need to physically turn it off (the I/O switch on my PS) and let the capacitors on my board empty out before starting it up again.

UPDATE2: As of 2 weeks ago, it won't boot at all. UPDATE1: HDD booted OK, but I don't know how to copy the GRUB file. Could this be a hardware temperature problem? I have just replaced a Hard Drive, & had to reinstall XP & 10.04.2LTS from scratch, (it was a TOTAL failure) The system now will not boot into XP, or either of the 2 Linux kernels or the recovery modes, without several attempts. ( I'm using a LiveCD now.)
POST is good. GRUB loads, but when I select an OS, it powers off. Windows shows the splash for a few seconds, then shuts down. Yesterday, I was able to boot into Linux after booting into Windows, but today Windows won't boot either. On examining the GRUB menu (e) the first line in the Linux records is 'recordfail' I will attempt to boot from HDD now, & post the GRUB output here. EDIT: If I run MEMTEST first, up to Test6, it boots normally.

1) When my computer boots up it stalls when HAL daemon loads. This did not happen until I plugged in a defective hard drive. Anyone have any idea of how to go about fixing this?
2) If I open the session manager system setting, and untick "confirm logout" my system will shutdown instead of logging out. With the option enabled my computer logs out normally. I don't need the confirmation and find it redundant and feel like Linux is holding my hand and that's why I use linux because generally speaking I don't like an OS that wants to hold my hand, metaphorically, I mean.

I want to create an unprivileged user account, say 'shutdown', which can be used only to shutdown the system. I followed the instructions in ut when I login into the system, I get this error 'Cannot execute /usr/bin/sudo /sbin/shutdown -h now: No such file or directory'.These are the configurations that I did
/etc/sudoers:

The ssh server is running Xubuntu 9.04. It was working before. Then I tried SSHing today and it gave me a connection refused. The computers I've tried SSHing from were running Ubuntu Netbook Remix 10.04, MacOS, and Solaris 10. None of them would connect. The ssh server is running the latest version of openssh-server (according to apt-get install). I'm assuming something in /etc/ssh/ got changed but I'm not sure.

I just did a clean install and ran system-config-network from command line to fix my IP settings. Everything works but when I reboot, my NIC is gone from #ifconfig -a
I have to login to the GUI and go to System --> Administration --> Network --> "Click on my NIC" --> check the box that says "Activate device when computer starts"
Once this box is checked, everything works fine. - I have turned off NetworkManager and just use the network service to manage my ip settings.
I was wondering if this "Activate device when computer starts" can be done through the command line without having to access the GUI?

I've got a computer i'm trying to VNC to.
The problem is that when the computer starts up/reboots it doesn't "Unlock the system keyring"(I think that's what it said).
When I try and attempt to connect to the computer it asks for the VNC password(as per normal) but fails to connect after that.
The reason is that the Ubuntu computer prompts for the user's password to unlock the system(locally).
What I want is to be able to turn on the computer without having to worry about entering the password. I've had it running fine on 8.04 yet the newer version seems to be annoying :s
The system is set to automatically login on startup too.
I've tried this: "delete the keyring folder under /home/XXXX/.gnome2" then setup remote desktop again. But that hasn't worked either. I still have to enter the password to a keyring

Sometime after I upgraded to ubuntu 9.10 I've been having trouble with my wireless network connection.It will usually log on to the network, then disconnect a shortly after. Then try to connect again, usually successfully, then it cuts off again. Then connects again, then disconnects. FWIW, ubuntu 9.10 works on a different machine pretty consistently, so I don't think its a problem with the router.

I've installed VMware server 2.x on my windows XP SP2 and installed Ubuntu 9.10 on the VMWare. I have noticed several times that the ubuntu machines shuts it down (not sure the time pattern but it could be that it shuts down after a certain minutes idle). As a result of that, I always have to restart it.
I checked the event log viewer, it looks like there's always a segfault just before it shuts down. I've pasted the last few lines of event log below.

I've been using Ubuntu on my desktop for a while and it worked like a charm. Three months ago, I decided to put a new cpu fan because the old one was gathering dust and I wanted to have lower cpu temps. I decided to buy an Scythe Kabuto, nd installed it with no problems. Windows XP works perfect, but the problems come when I try to start Ubuntu, both from a Live CD or from the HD. Ubuntu starts normally, but in a short period of time (2~15 minutes) the PC randomly shuts down. I've seen some errors when I restart and try to start Ubuntu again mentioning high CPU tempetatures. The fact is that the CPU temperature never reaches more than 65, so my guess is that there is some problems with the ACPI and temp reading.

Ubuntu shuts itself down and displays message that it is running low on graphics, giving me options to run in low graphics mode or to troubleshoot. I have been given the following advice but have no idea what to do:
You are using the open driver i915 as you are using an intel based video
chip.
Sounds like you need an xorg.conf file to define the display a little better as udev is not detecting. Here is a sample file you can start with: (Refers to a URL that led me to this forum)
You can ignore any sections and entrys regarding keyboards as udev is
pretty awesome at picking those up

I just had my laptop in the shop for a month or so now (through Staples warrenty) I sent it in because my LCD monitor wasn't lighting up after a bit of use.
Got it back and they said my issue could not be replicated, so they just cleaned it and such and gave it back. Well so far it's been going pretty good, monitor stays on except when i turn on Heroes of Newerth.
What kind of problem is this and is it easily fixable?
