Ubuntu :: System Total Freeze / Get That To Work Again?
Dec 20, 2010
I'm having a problem with my Ubuntu 10.10 system. After installing the OS it worked fine. But after one or two restarts it totally freezes i mean NO Ctrl+Alt+Bckspc , NO Ctrl+Alt+F1 and Ctrl+Alt+Del works for me. I have the same problem with Ubuntu 10.04 , 9.10 also. ( Only Ubuntu version 9.04 Works fine for me ). But i want to make use the latest one. code...
After Ubuntu fails some time it crush the GRUB loader, so that i can't boot windows either. Any buddy tell me why this happen to me?
I've try to install Linux Mint 10 also but it freezes while installing..!!
Now I loaded the openSUSE 11.4 milestone 3. It works fine for now but i can't connect to internet , it asks for "linux-atm-lib" . i don't know how to do that .

I'm experiencing constant system freezes, and was wondering which log file to view in order to determine what is causing it. I switched over from linux mint as it was giving me the same issues now being experience on my debian setup.
When my system does freeze, the keyboard is unresponsive (caps lock won't even turn on) and I have to use the power button to get out of it. The only thing that does work is my wireless mouse which I can still move around.

Ubuntu boots fine with wireless turned off via the laptop wireless button on the case, and fine with wireless on but no networks remembered, but as soon as I try to connect to a network, I get the strobing wireless icon in the top panel and then the whole system freezes. It switches to a black screen with a non-flashing terminal cursor in the top left corner of the screen plus a frozen mouse pointer in the last position from when Ubuntu was working. If I force a power-off after this, which I have to, then unless I manually turn off wifi using the laptop button then Ubuntu never boots and I just get a black screen after the BIOS screen. I can connect to the internet via wired connection.

I installed 10.10 this morning from the live CD. Everything working perfectly whilst at home, but now I'm on the move I'm having troubles.At my parents' house trying to connect to their wifi. Wifi is on, their network is detected, I can go in and enter the WAP key and I get the strobing wifi icon in the top panel as though it's signing in, but after about 4 seconds I get a black screen and everything freezes. All that remains on the screen is the mouse pointer in its last position and a non-flashing cursor in the top left.

Ubuntu 9.04, all updates
Latest firmware, etc
abit SG-95 motherboard
2 GB Ultra DDR2
Intel Celeron 360 cpu
PNY GeForce 9500 GT video
Started 2 weeks ago, random and total freeze of system (video, keyboard, mouse).
Nothing useful in th log, other than it occurs at the same time syslogd restart show up in the log.
I don't even know where to begin, or how to troubleshoot the issue if nothing shows up in the log... could use some help, please.
Problem occurs with or without the nvidia drivers installed. Ubuntu or windows, same thing..connected or not connected to the internet
I've ran every memory test I can find, with no issues reported. HD seems OK. No other symptom that I can find, other than it croaking, usually when I'm in the middle of a broadcast or recording.
Is the only machine I have for now, I need to figure out what's wrong and replace it as quickly as possible, so I can get back to work.

I have installed Slackware 13.1 without a problem and have a working wired ethernet connection. However I need to set up wireless but each time I try to do this using wicd I have a total system crash during the start up screens at the very last line before the welcome line appears.
Nothing works to resolve it, and I need to press and hold the start button and restart. I have checked the md5sum, installed the software again several times but the same happens each time which results in me having to reinstall.
I have installed wicd using slackpkg update, then slackpkg install wicd.
I have also tried downloading wicd from the slackware /extras folder and installing it on its own. Either way the same happens.
I have tried various manual approaches to setting up wireless following various links but again without success.
I now have a clean install again but am not wanting the same to happen.
Can anyone suggest what I might need to do?
I am using an intel Pentium 4, 2.53 ghz, 512Mb ram, GeForce4 MX 440.

I was just trying to get used to everything and I noticed something in the task bar that said you have updates that failed to install (or something along those lines). So I opted to install them manually with YAST2 and during the installation some of the files were failing to download, I was unsure what to do with these files (their was a ton of them, I had to actually sit at my pc for over an hour because I couldn't let it go through on it's own due to all the failing downloads and installs) and so I just decided to skip them, everything seemed to be going along normally. Then my computer froze, so I restarted and tried to boot into opensuse and it kept freezing, (I even went to my brothers house to play the xbox with him for a while) and no matter how long I waited for it wouldn't boot into opensuse. I tried the failsafe mode and it just kept coming up with an error (I probably should have written the error down, I wasn't really thinking about that at the time) and after about half a dozen tries, decided to reformat everything all over again.
So with these failing downloads in YAST2, what am I supposed to do with them? If I retry they just keep failing, so the only other options are abort and skip, am I supposed to skip them or is that what caused this to happen in the first place?

Today while browsing the web and attempting to listen to a mp3 file on the site of a musician, this laptop with Lucid CRASHED badly! It went into a black screen and the only solution was a reboot! I am not a masochist, but I could repeat the crash a couple of times just to verify it.
This is the worst crash that I have seen on GNU/Linux! I expect things to go down in a more controlled way: maybe first the crash of a plug-in, then the crash of a web browser, eventually the crash of a windows manager. But I don't like seeing that playing an mp3 is leading to kernel crash on what is supposed to be a LTS-release!
Any observations of similar behavior or hints on the cause? Is it possible that the crash is related to intel graphics 85x on this system that are now very problematic on Lucid?
By the way, the music file in question is probably not malformed and plays perfectly on Mac and Windows. I am digging into system logs to try to find any record of the problem. For the the record: I've been around Ubuntu since 5.04, on Linux since 2003, on Unix since 1988, and on computers since 1979.

I want to calculate the total amount of memory used by the system, Someone please confirm if the below formula is correct.Quote:
((memUsed-mebBuffers-memCached)*100)/memUsed => totalMemoryUsed%
Code:
free -o
total used free shared buffers cached
Mem: 8167004 8115292 51712 0 87680 1444676
Swap: 8388584 3252996 5135588
((8115292-87680-1444676)*100/8115292) => 81%
As per the above calculation 81% of memory is used.Is this correct? and if so Am I running out of memory?what is the limit in % that I should maintain for a better performance?

How can you give total access to the system to a user other than root?
* Make the user a member of the root group.
* Change the UID of the user to 0.
* Add the user to the /etc/sudoers file.
I think none of these are correct answers.

I'm running ubuntu 10.04 as a mythtv box and it works mostly fine. But occasionally the system will hang during booting and the last messages I can see are code...
So, I don't know. What is the problem? This system is supposed to run mostly unattended, I can't check all the time whether it booted alright.
So what can I do?

My partner and I share the computer, so we are normally both logged in.
When we come to turn the computer off, one of us will log out then the other shuts down (to have a clean shutdown), but when either one of us uses 'Logout' the system just freezes, no response, nothing, have to turn the machine off via power button.
We can 'switch user' fine, and everything else appears ok but log out fails, I did try reporting a bug on this, but seems to have got taken over with people with dual screens / SLI cards, taking it over and its not the same thing.
I get the 'impression' its a graphics driver issue, I'm using the 'recommended' Nvidia driver (am at work and can't remember which version sorry).

I'm putting this in general, because I'm not sure if many of the specifics are relevant.I have an everex cloudbook which I purchased from eBay with hardy herron on it.I finally got around, today (I've had it for a year), to installing netbook remix 9.10 with a usb key I had also purchased from eBay.Now, during the upgrade (using update manager) from 9.10 to 10.04, the system appears to have frozen.(desktop frozen, no response to keyboard or mouse).Now, I'm not sure if something could still be happening inside there, and if it would be a good idea to let the machine site overnight before rebooting it. Frankly, it happened once already, and I rebooted, and update manager just took up where it left off once I logged in.
I have not determined what's causing these freezes. It's not a new machine, of course (everex, afaik, doesn't even exist now), so maybe netbook-remix is too taxing on the hardware? I installed xfce to get away from the bloated netbook-remix graphical menu garbage, which did seem to allow the system to run faster. Anyway, the real question here is, while the interface appears frozen, could the upgrade still be developing under the surface? (I hear a fan running in there. There is no hdd to spin, but flash memory, so I don't know if the fan is any indication of internal activity). Would you wait to reboot it? (update mgr indicated 4 hrs remaining to upgrade, in the installing upgrades phase, not downloading, appears it froze during "Running post-installation trigger install-info"). Or just reboot it and see what happens (get update mgr to start again?)? The system never froze on me with hardy. It was pretty quick and snappy, in fact.

Running Ubuntu 10.4 32bit (only) on my system with ati graphics card. I just ran a software update, and I believe a new kernel was installed. When I rebooted, I saw the "Ubuntu" loading screen, but then the system froze up and the screen went completely blank. Thinking it was a graphics issue, I tried to press escape to get into the grub bootloader. However, when I pressed escape at the proper time, the system just rebooted.
Thinking that grub was broken, I used a live cd to purge grub from my system and re-install it. When I rebooted, I got the same initial problem: I get the "Ubuntu" loading screen, but then the screen goes black and the system appears to be frozen. Again, if I press escape to try the grub bootloader, the system just reboots.

Nothing too major here but today I had a few programs open and was doing a bunch of things and suddenly the system froze.
I am on 10.04 LTS -
Are there checks that I can do to see if everything is ok?
I had to turn the power off and re-booted and everything is fine, or rather, seems to be 100% fine - but more out of curiosity Id like to see if there are some checks that I can do.
I think that ubuntu creates a log of activity if I am not mistaken?

I am running Ubuntu 9.10 and trying to use OpenOffice 3.1. If I run OpenOffice, after 10 minutes or so, the whole computer freezes. Even if I have shut down OpenOffice it still happens. Only answer is to turn computer off and on again. I read some other people's posts listing the same problem and as a result uninstalled Open Office and then installed it again. I also uninstalled Compiz. Neither of these seem to be the solution. I have just installed Lotus Symphony and there are no problems with freezing and so the issue is definately with OO and Ubuntu.
I then on further advice uninstalled the bundled Ubuntu version of OpenOffice and installed directly from the OpenOffice website. The problem still remains. Next thing I tried was to uncheck autosave feature. The above problems only happen on my desktop. I also have an ASUS EEE Netbook running Ubuntu 9.10 Netbook remix. This is fine - the problem does not seem to affect the netbook. I would really like to continue to use OO - I like it a lot. Unfortunately this freezing issue is making it unusable.

[I'm not sure if this is the right forum. This is the closest I've found]. I've installed Ubuntu 10.04 LTS (dual boot with Windows XP SP3). After Ubuntu starts, it takes about 10 seconds, and the computer halts. No screen/mouse/keyboard activity. If I start Ubuntu under Recovery Mode, with failsafeX, it doesn't happen.
In the Windows all is fine. What did I wrong? [My CPU is: Intel(R) Pentium(R) Dual CPU E2140 @ 1.60GHz, if it matters...]

I've recently installed 10.04 LTS on a desktop PC so I can use it as a Zabbix monitoring machine.
I fresh installed and all seemed to be well but after a few restarts the system suddenly refused to boot anymore. The BIOS splash screen comes up and then a cursor blinks on the screen for a couple of seconds and then... nothing. The keyboard and monitor both go unresponsive and nothing happens.
I can hear the HD spin up and it isn't making any weird noises. Also, booting from the CD works and I can see and work with the HD so I'm not convinced that this is the problem.
In fact, I actually did a fresh reinstallation of 10.4 onto the machine and started from scratch. Again it ran fine for a few hours while I was setting Zabbix up. After a couple of restarts, again the freeze on boot.
I ran a HD scan and everything seems fine. I've also switched the HD over to the second IDE connection in the box just in case...
Does anyone else have this problem? Is it a bug? Any ideas on how to workaround it? (Short of going back to a previous Ubuntu version)

When I do some copying of files, or any background disk activity with file reading (transcoding a movie, uploading a big file to FTP, virus scanning) all computer becomes so slow, that I hardly can move my mouse, not to mention any productive use. I have SATA HDD, and Intel Quad CPU. I took measures to be sure it is not CPU or memory resource problem. Gentoo, Fedora, Windows don't freese that much on file reading. It is not a filesystem problem, or HDD, cuse I tried exactly this partition with other OSes.
Nice has a minor effect, but is is not enough, and I can't always start Nautilus with another nice level when I want to copy a file. What can I do to lower the priority of disk operations globally, and make apps to share disk thoughtput equally, not the one to occupie the disk until it finishes?

I seem to be having a problem on the new Kernel (2.6.35-23) with the system randomly freezing.
I have installed a number of things in recent days leading up to this problem, but when i boot with the old kernel i don't seem to have any issues. From this i am guessing its the new kernel.
The freezing seems (although i am not sure) to be worse when Rhythmbox is running. When it happens everything freezes, the playing song skips, replaying the same one second of music over and over. All the hotkeys stop and the mouse cursor stops responding.
I have seen people talking about system logs to look at system crashes but i don't know how to show those. I also doubt my ability to interpret them.

I built a new system for 11.04
Intel i5
ASUS P8H67-M LE motherboard
4 gigs of ram
2TB Hard drive
DVD writer
I am getting system freezes, but the mouse pointer still responds (moves arounf).
I suspect that it is the Sandy Bridge video. The freeze is preceded by video corruption.
How do I proceed to get this resolved and report the errors to the development people?

I frequently (i.e. after 10-20 minutes of use) get a complete system freeze when using LibreOffice Calc 3.3.3, on Ubuntu 11.04. At the time, I have an *.ods file open, and the freeze happens at various times, for example just after pressing the Page Up button. After the freeze occurs, nothing responds, not even Ctrl+Alt+F1, and I have to force power off my laptop.
how to debug this problem, as there's no error message, no error log (that I know of??)..

Basically they all cover running a 32bit app running on 64bit host and so on.I want to have an isolated system in total chroot (running lighttpd, mysql, ssh, etc from there).(For security reasons I have to isolate the dev from the live one.) So I installed the chroot environment, mounted all the neccessary things and chrooted in. Everything went fine. Edited /etc/ssh/sshd_config to use port 22222 instead of 22. Used service ssh start then. It says service running but if I try this: ssh -p 22222 localhost I get "Connection refused". The chrooted is system is very minimal so far so there is no firewall, hosts.allow/deny or anything.
ps.: The chroot environment will be a development area as I already mentioned. I thought chroot is the easiest way but if you say KVM is better or something I can go for it. The machine is easily capable of running even 10 VMs easily.

I updated 9.10 and system crashed during update and is now unbootable. It seems to freeze (or is just taking a really long time) at fsck. Is there any way to make my computer usable again without reinstalling the whole OS?

So when i initially boot (both using wubi and a usb stick.) it will start to go and then do the alternative boot option with a 5 second count down. Then if I'm lucky it will get passed that then either a black screen with just a flashing _ on it and it will freeze there. Or it will go to the ubuntu opening with the little dots for initial boot and it freezes there. (the dots don't move more then two and then it really freezes.) My specs are
i5 750
Nvidia Geforce GTS 250
1.5 TB harddrive
ASUS P7P55-M LGA 1156 Intel P55 Micro ATX Intel Motherboard
Windows XP home edition 2006 with SP3.

I recently installed ubuntu 10.10 and am completely new to linux. Something I recently noticed is that my whole system will freeze 2 times after logging back in, but after that it works fine. I will log in, then it will work fine, but shortly after it will completely freeze. After about a minute, it will unfreeze and everything will work fine. Then after a little longer, the exact same thing will occur. After the second freeze and unfreeze, it never occurs again until I log out and log back in. I do not believe this occurs when first starting the computer.
