Ubuntu :: System Crashes Randomly?
Jun 7, 2010
I have an old PC in my basement that I decided to load Ubuntu onto a few months ago. I ran version 9 for a while and then recently upgraded to10.04.Unfortunately, I've been having issues with intermittent system crashes using both versions. Sometimes the computer will work fine for hours and other times it will crash 20 seconds after startup. I'll be able to provide much more information tonight when I get home but for now I wanted to plant the seed in the forum and see if anyone has any ideas.The computer will be working fine and then all of a sudden the screen will go black and then start blinking, switching between a blank screen and a blank screen with a bunch of tiny white squares/lines. When I restart, things seem okay again.

I upgraded 10.04 to 10.10 (32bit), the upgrade process didn't go that well because first it didn't boot beyond GRUB. Solved this by unplugging my keyboard (my ubuntu is a server machine without keyboard or mouse, I like to use the desktop version through vnc). After that is booted to shell, which was not so nice either. This time it was the legendary nouveau driver which sorry for my language I will never install again (caused major problem twice already). Installed nvidia drivers and got a display for X this time and it booted nicely to login screen.
My problems have arised since the upgrade, the system will randomly "crash" and go straight to login screen, ending my current session. Sometimes my mouse cursor even changes to the X-mark. I can't see anything in gdm, x11, syslog etc. that would explain the crash. So far I've found best log from .xsession-errors which is here:
[Code]...
I got a lot IPv6 errors on the same log too, but those were caused by utorrent+too old wine. Didn't remember that upgrade deletes/disables extra-repos and I was running the stable wine (1.2.1) instead of the latest one (1.3.7). Upgrading wine solved the error from utorrent IPv6 connections.
So any ideas what I could do to fix these crashes? I'm not so much into clean re-install because of all the configuration I'll need to do then. I do have home on a separate partition but there's lots of software to install and configure.

When I opened Banshee today and tried to play a certain song, the player crashed. When I opened the player again, it continued to crash for only the same songs.
Here's the output:
Code:

Installed today on a toshiba satellite. Everything works great but it randomly takes me to a black screen. Sometimes looping music playing in the background sometimes just freezing all together. I dont know what error logs to post and there isnt anything specific going on everytime it does this. Music isnt always playing , once I was even logging out.It has happened with and without unity.

I have Iceweasel 38.6.0 on Jessie 8.3, and it seems to crash more or less randomly. It just suddenly disappears, and when restarted, it gives that "embarrasing"- thing. The pages reopen fine and it may take a day between crashes, or about an hour.
Where should I look for the reason of the crashing? Is there a log file or something somewhere?
My machine is old StinkBad T400. I'm using Cinnamon.

I managed to actually get Xubuntu to install, the previous time!Here is what happened. Installation went smooth. Restart.Log on, start Firefox, close it, wait a few seconds, crash.Restarted, it's now in a higher res. Ok, used an xterm to install LXDE. Reboot.Log into LXDE, play around, crash.Restart, repeat, use Firefox, after a while of browsing, crash.The mouse still responds to movement though....The person this was intended for uninstalled it afterwards. (it was with Wubi) I'd like to fix this.

Firefox crashes randomly. Frequency: few minutes to hours. It is not website-specific. Happens on both flash and non-flash sites. Seems to happen more often when I'm doing something complicated, like editing a photo album on facebook,or using a javascript-heavy page. Safe mode does not help.It used to work perfectly. I don't remember when the crashes began, possibly a month or two ago... So I don't know if they are caused by an update or by something I installed.
Most solutions I found were for problems with the Firebug extension (which I don' have) or for problems with fullscreen flash (which is not the case).Firefox 3.6.8, fully updated Lucid 64bit When started from terminal, it sometimes outputs an exception at startup, then nothing, then "Killed" before crashing. As below:
Code:
[Exception... "Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIXPCComponents_Utils.import]" nsresult: "0x80520012 (NS_ERROR_FILE_NOT_FOUND)" location: "JS frame :: file:///home/viktor/.mozilla/firefox/y4yoxvhi.default/extensions

My supposedly stable system was crashing. The problem was one or more specific screensavers--xscreensaver, the display manager (lightDM), and X itself are innocent as far as I can tell.
I'm on a Thinkpad T400 with Debian Jessie (8.4)/MATE/lightDM. I have libreboot and not proprietary BIOS. I like variety, so in addition to installing xscreensaver itself (the unofficial patched jessie version without the "out of date" nag, which I got from https://angband.pl/debian/pool/main/x/xscreensaver/), I also installed some extras from the official repository (xscreensaver-gl-extra, xscreensaver-data-extra, xscreensaver-screensaver-bsod). I enabled all the installed screensavers and asked xscreensaver to randomly cycle through them.
To my dismay, after variable lengths of time (usually within 20-60 minutes), when a random screensaver has been on for a little while (I'm guessing as it's about to go to the next random one), X crashes to a black screen. The only way to make the black screen go away is to kill X (which I mapped to Control + Alt + Backspace) then log back in. There are no useful logs anywhere except some cryptic IO error 11 entry in ~/.xsessionerros.
Now for the troubleshooting:
1) First I tried installing a more up-to-date version of xscreensaver (5.34-2), which I grabbed from the sid repository. This didn't work--same problem as described above. Therefore, I went back to the patched version for jessie (5.30-1 from angband.pl).
2) To exclude that the lightDM middleman was the problem, I disabled it and was logging in with startx. Problem did not go away. (I then rigged systemd to log me in automatically and for startx to run automatically once I'm logged in--who needs middlemen?)
3) To exclude screensavers butting heads, I uninstalled mate-screensaver and disabled anything from X that could be interfering (by running these commands in a startup script: xset -dpms; xset s 0 0; xset s noblank; xset s off). Problem did not go away. I kept this startup script nevertheless.
4) Finally, to exclude individual xscreensaver module(s) being the problem, I unchecked them all. Then I wrote down the names of my 20 favorite modules (which include some from gl-extra, some from data-extra, and bsod) and tested them in small batches, running xscreensaver with only 5 favorites checked at a time. After testing four batches of 5 and witnessing all 20 favorites both display and load without any X crashes, I went ahead and selected all 20 favorites. I left the laptop on overnight and in the morning (about 12 hours later) it's still going strong.
One or more particular xscreensaver modules are crashing X, probably at the time they are being loaded to be the next one to show. I think I already spent enough time on this, so don't really care to identify +/- troubleshoot the offending modules.

I've upgraded from stable to testing.In stable, iceweasel performed flawlessly as I expected. Now it crashes at random times at an alarming rate.It does seem that I can recreate the crash to an extent on ....., where crashes are the most prevalent.I haven't located any bug reports regarding this issue with wheezy iceweasel.

I've got the latest version of Flash installed,and it works most of the time,t occasionally a video or game will stop working and the area it was in will just turn into a grey box. Usually it only does this if I leave the page the video's on, but it keeps doing it when I'm playing Robot Unicorn Attack on Adult Swim's site, too

I recently re-installed ubuntu to fix my freezing problem, but with no success. disc has no errors. I cleaned the disc and the cd drive, the cd burner has a problem installing while the dvd drive does fine. The computer is a HP Visualize X-class workstation with dual 1000mhz pentium 3s, 2 gigs ecc ram and a ATI AllinWonder 9700 pro @ 2x agp(wish was higher), on-board sound. So my problems are:
1) It randomly freezes within 24 hours regardless of who is logged in or if effects are on or what the load is. mouse is frozen too, completely unresponsive even ctrl alt f1.
2) My sound is screwy. its supported by alsa but i have to play with the volume to get sound and lots of times there are audio errors, it sounds like its robo-trippin. I have tried the sound guide.
3) Desktop effects only work with the user that logs in first. If I try to activate them when I switch users it searches for drivers then says it cant be enabled. not a priority.
Window xp works okay but the graphics drivers are giving me problems so i decide to do a dual boot.
I think I am going to put in a different video card. maybe its not all there, it got hot once when the fan died, put in a replacement and it worked but i see lines moving down the screen when there are blacks.

I'm at a loss in trying to debug a problem I have with my media centre. Basically I'm getting random system hangs and when I say hang I mean proper hang - processor stops dead. No animation, not network connectivity, no keyboard/mouse response, nothing. As for it being random - it has happened during movie playback, during idle, after being up a short time, or a long time, it doesn't matter, so it can happen any time really. The logs show nothing suspect, except they just stop and there is nothing common between the logs of two failures. It happens on both my 'old' ubuntu 9.04 partition and on my new 10.04 partition.

Running CentOS 5.5 on a Dell PowerEdge 710 with a mirrored RAID. System randomly reboots leading to MySQL table corruption as its not a graceful shutdown. Here is the output of the getinfo shell script [URL]. Some data has been obfuscated such as public ip addresses. Prior to posting this a full hardware diagnostic was run by the Data Centers support team which turned up nothing.

My Ubuntu Karmic running system experiences random lockups. There is no pattern in when it will happen, it can go for days without one, or happen every couple hours. Only thing I can notice is that it happens most often when I run Firefox, but when it happens, it happens regardless of me having Firefox open on a website with lots of Flash content or not. When the lockup happens, I cannot move the mouse - the led light on my mouse shuts off, I can't move the cursor, the whole UI becomes unrensponsive, there is no blinking lights on the keyboard, REISUB does not work, only hitting the reset button on my case helps. After reboot, there are no indications of errors in any of the logs that I can see.I have ran memtest for 24 hours, and it completed without errors.
Additional information:
1. LSPCI output:

Whenever I'm browsing the web on one of my natty machines, I'm subject to periodic reboots that leave nothing in the syslog. Here's the two constants I've discovered thus far.
It only happens when I'm using a browser (plugin?).
It doesn't matter whether I'm in Chromium or Firefox.
It doesn't matter whether I use Unity or Gnome 2.
This happens every 2-3 days from what I can tell.
This problem is not power related because I've tested it with and without an UPS present.
The computer does a full reboot without any shutdown procedure.
The configuration of this computer is as follows:
Intel i3 2100
ECS H67 Dual Nic
Haupaugge Dual ATSC Tuner
MDADM RAID 10
8GB 1333MHz (MemTested)
The browser plugins are as follows:
Flash 10.3r181
VLC Multimedia Plugin (compatible Totem 2.32.0)
Windows Media Player Plug-in 10 (compatible; Totem)
DivX Web Player version 1.4.0.233
QuickTime Plug-in 7.6.6

I am running the Nvidia driver. My system freezes randomly. I've had to reboot my system over 5 times today alone. When it freezes, everything is frozen, even the second hand on the analogue clock. One more issue, and I'm not sure if it's related, my stupid screen goes black after 5 minutes of no typing or mouse movement. This never happended when I first installed it. The issue just started within the last 3 weeks. Kpackage Kit is hidden. I was using it to do my automatic updates. Now I just use yum. between the time I first installed Fedora 12 and now, something has happened to my build to cause these issues.

I noticed that sometimes my Linux server will randomly start to lag really badly, to the point where even a http request takes forever. It is an Intel Core2Quad with 8GB of ram running FC9. This is my "Everything" server so it does file, email, DNS, web (for local stuff only), VMs and so on. There are about 5-6 VMs running on it at any given time. I manage it through a VNC session and have some SSH consoles within that session. This way if I reboot my PC I don't lose all my SSH consoles. If I need to SSH to any server I do it from there. I treat it kinda like a terminal server to some extent.
When this slowdown happens, top is not really useful because I also do F@H so that will always be to the top, but it's low priority. The VMs are also always near the top. This does not change whether it's slow or not, so when it's slow, I have nothing to go by on how to troubleshoot. The load does seem to skyrocket though. Right now it's doing the slowdown thing and it's at 8.09. Normally it's at around 3 which imo is good as it it's under 4. I have 4 cores so anything more than 4 means it's queuing. At least that's how I understand it. This is the output of top:

I upgraded not so long ago from version 9.10 to 10.04. What never happened before then started. I have system crashes all the time. When I play Solitaire, use Firefox and copy files.
I use ubuntu now for several years (at least since 8.04) and I never had a system crash before. I have a P5P800SE motherboard, a celeron 3.06 GHz processor and use 512 MB of memory. Ubuntu is installed under windows XP professional version 2002 service pack 3.
If not I will return to version 9.10 and wait for version 10.10.

I installed Ubuntu 10.04.1 yesterday, and I've been trying to install my nvidia 240 drivers for it. I've done this multiple times on 9.## and it worked fine. When I try to install them it says i need to shutdown xserver. so I open terminal and type sudo /etc/init.d/gdm stop screen goes blank and all there is is a flashing _ at the beginning. I'm not able to anything except type, but no commands work.
So, I tried starting it up in recovery mode root shell or whatever, and it shows the command prompt. Then I login, and it says welcome, I go to my downloads folder and type sudo sh NVIDIA...256.44.run and it says I need to be in telinit 3, so I get out of the installation and type sudo telinit 3.well that brings me up to a login command so I type my username then it askes for a password, which I also fill in.Now it says incorrect login. So I try again, and it keeps going on, but then I noticed that it puts the first letter of my username infront of Password.And the only way I can get out of that is by Alt + Ctrl + Del to restart, same when I shutdown gdm.

I have been using Kubuntu for a LOOONG time now, completely happily without any noticeable problems. But, on my birthday, with the help of a few contributions, I was finally able to upgrade my PC to a Core i7.
And for the most part, things are still smooth sailing. Except for Kopete, which randomly crashes at times, bring the entire beast of a PC to a halt. Basically what happens is it suddenly lets off notification gongs like a machine gun. Then there are windows that popup that say something about "Yahoo Plugin Error". And judging by the number that increases in the titlebar, it makes A LOT of those windows. But the contents of the window itself are never rendered. It usually gets up to about <105> before the entire system just freezes.
The only difference between my old system and this one, in terms of software is the change from 32 bit to 64 bit. If someone could tell me how to fix this problem, or just point me in the right direction, it would be greatly appreciated. This is driving me insane!!

I've recently installed Fedora 14 (x86_64) on my Alienware m15x laptop which has a NVIDIA GTX 260m onboard. Now I have followed leigh123linux's guide to installing those drivers on F14. The installation is a success and everything seems to be in working order, until the system randomly logs the user out and/or restarts the session with no warning. The screen goes black and the nvidia logo appears and then its back to the login screen again. This can happen many times with no apparent stop insight. This does not happen with the default F14 drivers that come with the installation, I have tried several re installations of the Fedora OS and several re installations of the NVIDIA driver, i still have the same problems.

Well, turns out that when I rebooted into the installed system a user setup utility launched, but now whenever I try to log in as me, X crashes and GDM starts up again, telling me to relog in.
Now it's the case of "A setup utility launches and I set up my user, only to try to log in and get kicked in the face by GDM, having done all that work for nothing".
