Ubuntu :: Computer Freezes - Then Applications Wont Run ?
Sep 12, 2010
Acouple of times now, my computer has frozen while I had firefox and eclipse open. when i restart it, firefox will not run because it is under the impression that it is already running; eclipse will start up, but does not allow me to access the necessary workspace because it is under the impression that it is still in use. how can i get rid of these problems? i tried pkill for firefox, but it does not show up on the list of processes running...

I boot linux from a usb drive so I can carry my distro wherever I go - I've been doing it for quite some time now and it's always worked wonderfully. Problem: This morning my little cousin unplugged the computer WHILE I was booting into linux. Power loss has happened before, but with no ill effects. This time however, it's decided it won't boot. The screen clears, and just as GRUB is about to load, it freezes and the computer reboots over and over.
I booted to a LiveCD of Ubuntu to try and fsck the drive, but it won't mount the volume. I've worked with this install so long, and have customized it so much I **really** don't want to do a reinstall.. What can I do?

I am running Ubuntu 10.10 on a Lenovo Thinkpad T61p with 2GB RAM. When I was on Ubuntu 10.04, one day suddenly Azureus hung at the 'loading plugin' screen as it begins. I had to hard reboot my system and it(Azureus) never worked after that so I removed it. Then after a couple of months same thing happened with Adobe Acrobat reader. As soon as I opened any pdf and started to scroll, it hung. System didn't respond and had to hard reboot. I moved to foxit reader Then I upgraded to 10.10 and now mplayer hangs occasionally if I try to switch it to full screen. System stops responding totallyn Where to begin debugging from ? I can't figure out any pattern or any way to reproduce it. I haven't tried Acrobat reader and Azureus on 10.10

I have installed Ubuntu 11.04 Natty Narwhal. I'm using the Gnome desktop (Ubuntu Classic) instead of Unity.
My problems is, when I launch certain applications, most of the time LibreOffice ones, Ubuntu desktop freezes.
When this happens the desktop becomes unresponsive to the keyboard. However the mouse pointer can still be moved around. Everything on the screen will freeze including panels and their items.
This happens only when an application launches.
I have already set up a shortcut key combination so that Ctrl + Alt + Backspace will perform a session restart. But when the above mentioned problem occurs, shortcut keys do not work (so I can't just do a session restart). So there's nothing to do other than restarting the laptop by holding the power button down.

I have dist-upgrade from Wheezy to Jessie, however it randomly freezes. Everything was okay with kernel 3.2, but when I run several applications kernel 3.16 fails.
At below you can see the dmesg output of Jessie:
Code: Select all[ 0.000000] Initializing cgroup subsys cpuset
[ 0.000000] Initializing cgroup subsys cpu
[ 0.000000] Initializing cgroup subsys cpuacct

I recently installed Ubuntu on my spare comp.
It freezes after about 10 seconds after logging in. I don't know why this happens.
It's a Dell Dimensions 4100. Installation went fine. I did everything, didn't skip any checks. It finished normally.
And now my hopes of another working computer have gone down the drains.

I've a new Dell Precision T1500, Core i5, 8gb RAM, nvidia graphics card, that seems to freeze after some hours. I'm not sure how long exactly, more than two hours at least.
OS: Ubuntu 11.04
Cause: leave computer turned on, unattended for some time >2hrs.
Symptom: Screens are blank, no response to keyboard or mouse input, reboot is only way to rectify.
Things I've tried:Turn off screen saver
Disable "Sync to VBlank"
Disable screen power management, screen stays "on" always
So far none of these have corrected the issue. The screens are still on, but there is nothing displayed. Same thing did happen with Ubuntu 10.10, I'd hoped maybe 11.04 would fix it, alas, no.

After 6 months or so I noticed my 9.10 install getting sluggish and it started to freeze habitually. I let it go until one day it consistently froze at the startup login screen. I installed 10.04 and the problem continued - After first installing it worked for about 6 hours without a crash, and then once again the problem developed into consistently freezing at the login screen.
I tested with some USB Live sessions and my live sessions never froze, even when active for a whole day. Remembering some I/O BAD SECTOR error messages from my 9.10 crash, I determined the error may be with the hard drive so I bought a new Hitachi SATA hdd (needed more GBs anyway). I installed 10.04 on the new hdd (H and after 6 hours again it crashed. When it crashes the screen freezes for about 3 seconds and then the graphics wildly split and it's just a jagged gray screen. However, as time has gone on over the past 2 days, the freezing situation has been better in that it hasn't come to the point where the computer consistently freezes on the login screen. The time before it freezes has varied from 10 minutes to 6 hours.
I think it's maybe a software issue with the nvidia drivers. I'm having trouble diagnosing this bug or providing information. I've included the output of lspci -vvv I have the nVidia GeForce Go 6100 graphics card

I installed Ubuntu Lucid on my computer a few weeks ago (fresh install, formatted). But recently I've been having some problems.
This is about the 4th time it happens. When I randomly open a program, sometimes the whole computer will just freeze. I can't change to a terminal window with Ctrl-Alt-F1,2,3,4 or anything. I can only press the Reset button on the computer case. This is frustrating because I already lost ALL my firefox settings and addons and I don't want anything like this to keep on happening.
The problem was: *drumroll* the POWER SOURCE.
Apparently the voltage was having little drops and this caused all the hardware to freeze. This caused the system operation to be WORSE after I bought the new graphics card (since it was bigger and needed more power). I bought a new powersource and installed it and it seems everything is alright now.

I am using a 64 bit version of Ubuntu 10.04 on my Dell Studio. Sometimes my computer stops responding. I wouldn't say completely frozen, kinda semi-freeze. I am able to see the mouse pointer move and also when I move the mouse pointer over the Maximize, Minimize or Close buttons, the buttons get highlighted but I am unable to click on them. Alt+Tab key combination to move to another window doesn't work either. I experienced the same problem when using Ubuntu 9.10 64 bit for which reason I dumped Ubuntu then.

I have a Asus UX30 with an Intel GMA 4500MHD laptop with ubuntu, working with no problems except that when I'm watching some video it often freezes. The screen turns black and the only way to get it some where is to shutdown in the power button. Is there any special reason for computer suddenly freezes

Just wanted to upgrade my desktop computer and after the terminal shows:
Installling new version of config file /etc/apparmor.d/usr.sbin.cupsd ...cups start/running, process 7944
The display froye, mouse does not move any more, keyboard does nothing, no chance to escape into a text terminal. Nada. After rebooting the system I get a kernel panic. This is now second of two upgrades to 11.04 that failed, and I do not know how often upgrades failed previously, but rather often.

my wife's desktop has been freezing almost daily, leading to a reboot. It's an HP Pavilion (specs here) and it has Ubuntu 11.04 installed since soon after 11.04 came out. There doesn't seem to be really any rhyme or reason to the crashes, except that it might happen more often when she's web browsing with Firefox. I tried looking at /var/log/syslog, but to be honest I wasn't really sure what I was looking for. I did notice that syslog would stop recording at the same time the mouse and keyword freeze. Has any one seen this problem or be able to give me some advice on how to find out what's going on?

Yesterday I updated my computer from 9.10 to 10.04. When I restarted my computer it appeared this message:
Ubuntu is running in low-graphics mode. The following error was encountered. You may need to update your configuration to solve this.
(EE) No devices detected.
After that, it comes a window with the question "What would you like to do?" and 5 options...
Run UBUNTU in low-graphics mode.
Reconfigure graphics.
Troubleshoot the error.
Exit to console login.
Restart X
I'm going now with the first option, because I used to reconfigure graphics but my computer freezes with no aparent reason in the login window. I have a HP Pavilion 7956.

I had been happily on Jaunty Jackalope until they stopped supporting it so I took the forced upgrade and it's HORRIBLE!
I feel like I'm back in Windows land. Within an hour of my first load I had my very first Ubuntu total-lockup. Just like Windows. In the 18 months I'd been using Jackalope I had not had a single crash. Not one.
It's slow, jerky, and has odd freezes. Just like Windows. Applications randomly stop working and die. Just like Windows.
Is there any way to fall back to Jackalope or is there any hope of them fixing Koala? 'Cause this is wretched.
I see there's another version out there...10.04.01.LTS. I'll try that. It can't be much worse.

I seem to have a small problem. Since september, i hooked up an old Acer laptop (with just 560 RAM and a 16 mib graphical card) to a computer screen, a keyboard and a mouse, so that i had an extra 'computer' for my mother to use. Old people prefer bigger screens to ponder upon.
But anyways, each time i want to update or upgrade the 9.04 Ubuntu distribution, it freezes. This is quite annoying since i really want it to upgrade to 9.10, for possible faster results.

Since I upgraded to Lucid, I am dealing with serious instabilities related to my wireless card. What happens is that when there is a lot of wireless activity the computer freezes. It is a complete freeze, the mouse stops moving, if something was coming out of the speakers it keeps echoing, and the only solution is to turn off the computer. The bug seems to coincide with the one listed in here

My wireless card is Intersil ISL3890/ISL3886. My whole computer is an HP z555. I'm thinking that is should be a bug in the wireless adapter driver, which is p54pci. The only solution I can think of is to blacklist it and set up ndiswrapper. I am not very comfortable with this solution since a native linux driver should be better than ndiswrapper.

Whenever I run for instants skype, facebook, and a video call it seems like my computer can't handle it and it constantly freezes. I'm not sure if I have the wrong settings or what; but it never did this when I had windows installed on this pc. I would love to keep ubuntu but I can't handle it freezing every 5 minutes. I'm kind of computer retarded when it comes to this ha so sorry. I am on 10.4 9.10 froze just as much though

When I run a java application (minecraft) the computer occasionally freezes. I'm not sure which version of Java I have. The online java app for telling you which version I have says that I have an old version. The command line says I have an up to date version. If I need to update Java Sun , how do I do it ? I followed the instructions once and didn't work.

I recently installed Debian Jessie, and I am fairly new to Linux. I have both IceWeasel and Chromium, and every other time I try to use either, it freezes the whole computer, the screen shows only diagonal colors, and I have to hard boot. I have another windows and linux computer on this network with no problems at all. I have run checks on the ram on this computer which found no problems. Everything else on the computer works fine.

I start using Ubuntu, after successfully installed it without any problem.Then I downloaded latest updates, etc. But,after installing a display driver, my computer freezes, refusing to go beyond the welcome screen. I tried several ways but could not solve the problem. So I decided to re-intall Ubuntu, download again the updates, again configure my settings, etc. herefore, I'd like to know whether there is any application to backup or to create a full image of a hard disk so as to avoid the long hours of re-installation.

I have this problem on my workstation. The computer would effectively freeze for 2-5 seconds for no apparent reason, then continue as normal. While frozen the mouse would still be movable, but only on one of screens in my multi-screen setup. What can be the likely cause.
System:
CPU: i7-920
Memory: 12G of Patriot DDR3, 6 modules
OS: SLED 11, Suse Linux Enterprise Desktop, using Gnome
Main board: Asus P6T
Video: two Nvidia 9500GT connected to three displays
I am using memory at recommended settings of 8-8-8-1333. It has an XMP profile. Th CPU is a bit overclocked to 3.3 GHz, but my cooling more than allows for it. I ran the computer with all overclocks off and lower memory speed but the issue was still there.
