Ubuntu :: Screen / Everything Freezes From Time To Time For No Reason In Natty?
May 4, 2011
Ever since I installed Ubuntu Natty, from time to time, for no particular reason, the entire computer screen freezes, and I am forced to hold the power button on my laptop to restart things with a hard reset. I cannot explain why it happens.
Such an issue never occurred in any of the past installations and versions of Ubuntu. This is a fresh installation of Natty by the way.
Also, I can currently be running a lot or nothing and it does this. Thus, it does not matter what I am actually doing (ie, what programs I might be running).
It has occurred about 10 times since I freshly installed Natty 6 days ago.

I don't know why but since I upgraded the KDE 4.4 desktop from openSUSE 11.3 to 4.5, the desktop just freezes some times.
If i was listening music, or watching a video I can still hear everything and even move the mouse, but nothing works.
So I switch to TTy1, perform a init 3, then init 5 to restart all the graphic system, and start again. This happens without message, without log, and without clue...
Should I downgrade to 4.4 or this has a Workaround?

I have been a happy Ubuntu and other distros user from 2007 to now. Had my old 7.10 Gutsy Gibbon (Ubuntu Studio actually) that I really felt was time to upgrade. Then I downloaded the ISO image for 11.04 Natty Narwhal past 4 day ago. It gave me an option to install on my old 7.10, upgrading it, then I chose that one not to have to lose my data.
At the very end of the installation (when downloading several packages from the net) I got a kernel panic.
After that I reinstalled from zero wiping the whole partition, with the same results. It only worked when I disconnected the net cable so it wouldn't download anything during install. Then I could run the 11.04, but kept getting kernel panics, and after some testings (I thought it was the nvidia video drivers at first) I think it happens after some ammount of network traffic happens.
Memtest went normal, I tried logging with no-effects and I tried some solutions from forums with no results. The pc can be on and working for hours, but after I start surfing the web for some time, I get a freeze. Sometimes Caps Lock and Scroll Lock leds are flashing, and sometimes just freezes to simply become unresponsive. When it was during the installation I got a message saying it would pop out into console because panic occured and then froze. Anyway I always have to press the reset button.
I would like to be sure if I have some of my hardware broken or if the newest kernel is still green on some hardware support; maybe network. I'd also like to know if I can install older versions of the kernel; I think that should fix the problem because other distros worked perfectly here before. I also heard about some kernel-image-pae being different from the ordinary kernel image. Could it help if I change that package? I'm waiting to install 11.04 in my wife's computer also but of course I don't want to bring any problems on her! My net card is Nvidia Nforce and my processor is AMD Athlon II X2 with a GForce 9400 for video card.

I hopelessly tried to find answers for my problems but I could not find a single person complaining about this one: I am using a Lenovo G550 laptop (which has an NVIDIA graphics card) accompanied by a samsung screen using TwinView configuration. I have some special effects enabled and they all seem to work fine.
My main problem is: When I double click on the top panel in a window and maximize its size (it can be an application, a directory window or a terminal, anything..) on Natty, I sometimes can reduce its size back by double clicking on the Natty panel and sometimes this does not work! In times this does not work (reducing by double clicking again), I have to use the rectangle button in the panel in order to reduce it back. In times it works, I can simply double click on Natty top panel or left click on the panel, hold it, and pull it down.
What the hell can be the reason? I somehow observed a strange relationship between this behaviour and thunderbird but I am not 100% sure. Can anyone offer some help?
And another irrelevant question:
Is there a way to make the mail/pidgin indicator that turns green when a new message/mail recieved jump or move or do some action? Because when working full screen it is really hard to notice that thing going green. Previously on 10.10 if i'm not mistaken you could make the pidgin indicator jump high and low as a notifier. Is there a way in 11.04 to achieve this?

I've seen this issue mentioned before, but it appears their cause was different than mine.Here is a snippet of my dmesg log:
Code:
[ 2.797917] cdrom: Uniform CD-ROM driver Revision: 3.20
[ 2.798077] sr 3:0:0:0: Attached scsi CD-ROM sr0
[ 2.798149] sr 3:0:0:0: Attached scsi generic sg1 type 5[code]....
I'm not exactly sure what that is or why that's causing it to take so long to do.

I'm dual-booting Vista and Ubuntu. Ubuntu freezes all the time, like every 5 mins so I don't ever use it. I just do a new installation every now and then to see if it fixes itself but it doesn't. It says that the battery has a low capacity, could this be the cause?it only freezes in Vista when I take out the charger, about at the same frequency as in Ubuntu.

The system freezes all the time and I have no idea why, and the temp of core goes up to 56. Also, on the boot, right after grub menu selection, it restarts itself sometimes, again I have no idea why. I have lenovo y530. Which logs do you need?

I installed ubuntu 10.0.4 TLS version and my desktop freezes after a period of inactive time: the screen doesn't change and the apps do not response. It will resume after any key-stroke or mouse action. Is it a feature of 'power-saving' or something else? I need my ubuntu keep 'alive' all the time.

Can someone tell my why every time I try to use 7z it freezes my system? I can't move my mouse, I can't type, I can't kill my xsession. I then restart my system and everything returns to normal. When I try to use 7z my system again freezes.

I have two boxes that were originally used as workstations at a school - they upgraded and sold these.The two boxes are identical parts - Lenovo NetVista M42. I installed 5.3, installed RPMforge per the wiki instructions, did a yum -y update && shutdown -h now.The next day I turned the machine on and installed the UT2004 dedicated server. After a few hours I tried logging in via SSH - I could enter my user and password, but could not get farther. I rebooted the server. After another day the same thing happened. I moved the disk from the first box to the second and moved /etc/sysconfig/network-scripts/ifcfg-eth0.bak to ifcfg-eth0 but retaining the correct MAC address.
During this transition where the server "locks up" some things work and others do not. For example, if I type ping 4.2.2.2, wait 10 minutes and CTRL+C it looks like this (note the time of 0ms).

I installed network-manager-vpnc, configured cisco vpn through NetworkManager. It works slow, but the bigger problem is that after minute or so the connection just freezes.Then I tried kvpnc. It works like it should from speed point of view. But it also hangs up after minute or two.Tried to change MTU of my wired connection to 1500 - no good.Tried to uncomment line in /etc/ppp/options "mru 542" - no good.
Created /var/run/vpnc because it was giving some error "can't open pidfile /var/run/vpnc/pid for writing".From logs everything seems fine except for "nm-dispatcher.action:Script '/etc/NetworkManager/dispatcher.d/01ifupdown' exited with error status 1." in last line. If I use kvpnc it gives no errors.SO, how do I debug this thing or does anyone knows something I don't in this case?

I've been unable to resolve this problem for the past weeks and have come as far as I can trying to fix it on my own. I have a fresh install of 11.04 on a Shuttle ST20G5 with a Radeon Xpress 200g chipset. After 5-10 minutes of usage in X, it freezes solid (no response to alt-sysreq) and displays a white screen (sometimes with a pattern). I believe it's a kernel issue.
Things I've tried but still resulted in crashes:
- Switching to VESA graphics
- Running failsafe / Recovery Console X
- Downgrading X server to 2.09
- Running latest X server via ppa (at least, I think I did this. Maybe I didn't)
- Upgrading kernel to 2.6.39-0 via ppa
- Running the live cd
I get no warnings or errors of note in xsession-errors or kern.log
I have not been able to catch the error or obtain any troubleshooting info. When it crashes, it just crashes.

After some idle time Slackware hangs up/freezes. When, for an example, i turn on music i can hear it on idle time but after some time music still plays but i'm losing picture (monitor detects no signal), num lock is locked, led on keyboard are turned on but won't turn off while pressing num lock. I've switched off power saving options in Slackware and on bios setup.
My spec is:
X4 620 (without overclocking)
AMD 760G (Radeon HD 3000)
Catalyst 11.5 for Radeon graphic.
BTW - computer works fine with Windows. Also, with Slackware i can work for an hours, many hours and everything is fine but as soon as i leave it for some amount of time = it hangs/freezes. There is something wrong with hibernation. Not always computern is turned off correctly. TV is switched off, slackware logged off but i hear drives working and cooler fans. It should be switched off completly.

I've been using Thunderbird 3.0.x for some time and found in it a good replacement of TheBat. However, few days ago, ubuntu being ubuntu crashed and since then, Thunderbird freezes after 10 seconds every time I try to start it, sending CPU usage through the roof. I have 8 imap accounts in it and my profile folder is ~2.8gb I tried purging the installation. I tried fsck on all partitions. Windows Thunderbird using the same profile folder works just fine.

Attempting to install 10.04... I can get to the "Where are you?" screen, then the little circular "please wait" cursor spins forever and ever.
Here are a few things I've tried, with no success:Leaving it alone for hours, hoping it was just taking a really long time. No Dice. Unplugging any hardware that might be causing a problem, including the network card. No dice. Burning it to CD, DVD, and booting from a USB key. No dice. Trying every combination of kernel options I could find in the forums, and setting most combinations found in the "more options" menu in the boot screen. No dice. Booting into the live environment, then installing from there (instead of just choosing "install" directly). No Dice. Booting both from the 32-bit and 64-bit ISOs (my machine is 64-bit)
Note: I have not tried just upgrading from my 9.10 install, and I will not try this. If I can't get a live CD to boot, there's no way I would voluntarily hose my current system by upgrading.
Also note: I checked the MD5 of the ISO, and did the "check the disk for defects" menu option as well. Everything checks out fine.

I just upgraded from F11 to F12. Everything seems to be nice except mouse. The mouse buttons (both left and right, except middle one) are accidently frozen for some times. It could happen when opening a new tab in Firefox, launching a program, opening a new windows. I cannot click anywhere but can use mouse wheel. I have to log off/ log in and it becomes normal. It does not happen so frequently (around 3-4 hours) but it is really annoying.

I am trying to install ubuntu netbook edition on my Acer aspire one D150. I have tried to do this before with version 9 with no luck so I waited until 10 to see if the problem goes away; apparently it has not. I put the ubuntu install files onto a USB stick according to the instructions from ubuntu here for windows (I have windows xp on the netbook now).
When I shut the PC down and turn it back on with the USB key inserted, the laptop just seems to hang at the ACER splashscreen. This screen is where I could press F2 for setup or F12 for boot order; the buttons do not respond, the USB key appears inactive. Again, it just seems to hang. I've waited for as long as letting it run all night to see if it goes anywhere by the morning with no luck.

I'm trying to fix a friends EeePC notebook (Asus) running a recently upgraded Ubuntu 10.04 from Karmic Koala. She used the update manager for the upgrade to 10.04 LTS and everything was fine until she had tried to install something from the Ubuntu Software Center (she doesn't remember what happened). After that, both Update manager and Synaptic stopped working.Update manager gives the following error:Quote:Software index is broken. ... Try to use synaptic for something?!...
Then Synaptic manager gives the following error:Quote:E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. E: _cache->open() failed, please report.And when I try that command, the terminal just keeps blinking with the cursor and does nothing for more than an hour. This is the output of the comand:Quote:
jasna@Jasna:~$ sudo dpkg --configure -a
[sudo] password for jasna:
Setting up moodle (1.9.4.dfsg-0ubuntu4) ...

The screen of my years-old HP laptop (running Natty) freezes and eventually turns black. Ctrl-Alt-F# works to switch to the terminals. My fan is even louder than usual. I spend some time fooling around with ps and kill and shut down some of the most resource-consuming processes, which quiets the fan a bit, but tty7 still shows a black screen except for my mouse pointer.
I finally decide to shut it down altogether, but then I think to myself, "Self, you've used the power switch to shut down before in this situation, but shouldn't there be a more proper way to do it in the terminal?" So I try shutdown, I have trouble with it, it proceeds to get hopelessly tangled up, and it looks like it's frozen up in mid-restart when I throw up my hands and decide to go for the old power-switch-for-five-seconds method after all. Now when I start the computer and select Ubuntu from GRUB, I get this:

It takes me a while to log in the splash screen just sits there for ages before i get to the desktop. Never used to be this slow and I'm not sure why. Firstly, I'm running Ubuntu 11.04, standard DE. I do have conky starting up in a script but it has the & at the end of the line so I didn't think this would cause it (or is there some special case for log in time on how & is treated?). However as a test I will comment out the line in the script and see if it is the cause.
However just for general knowledge and in case that isn't the problem, how does one go seeing what is happening during the time from when one log's in and the desktop is displayed? Is there some kind of log that shows the date/time that can be enabled or is there a debug mode that can be enabled somehow via special keys or maybe from grub?

I have several file servers in our offices and I am relatively new to Ubuntu / Linux. I get notices that there are updates for the server software from time to time. Is it typical to update everything when available or should I follow "If it ain't broke, don't fix it..." mentality?I would hate for everything to be working fine and then have an update throw me a curve.

I am running my Ubuntu 32 bit server on top of Windows 7 64 bit with VirualBox. It's a 2 core Atom. It's been working good for about half a year. But the last about 6 weeks the system time only in Ubuntu is going slow. About -8 per 24 hours! I can only guess because I have more things running in my Windows 7 and Ubuntu.
I can set it right by coping the hareware time to system time with this command:
Code:
hwclock --hctosys
I want to run a crontab to have that command run every minute. But it don't seem to run.

I installed Fedora 15 last week, on my main PC, and I absolutely love it. Defintely my favourite operating system. Now I have a few questions. I thought I would put them all in one thread, instead of making seperate ones. I did search before I posted, and I cant seem to find any solution to my problems. So here it goes.
First question, I am using evolution for my e-mail program/client. My email addresses are all hosted by hotmail. Now I have set them all up correctly, but cant seem to send e-mails(I recieve them perfectly fine). I am using the "smtp.live.com" server, and using SSL encryption. I have tried messing with the settings but have had no luck. Has anyone figured out how to fix this?
Second question, I play minecraft frequently, and I am currently starting the program via terminal [java -jar /home/username/minecraft.jar], which works flawlessly. However it is too slow(open terminal, type it in. I need a simple click), is there any other way to start minecraft?
Third and last question, What is the best way to close minecraft? I notice if I just close it(via right click, and close, or clicking the X) it freezes and stays open for a long time. Is there any better way to close it?

I started out with Kubuntu RC, then installed ubuntu-desktop and updated all the way to the current state of packages.Anyway, from the moment I installed the RC, from time to time the boot splash appears, the dots light up/turn off and then the booting hags. No key seems to work.I the do a hard reset and everything works just fine.As not to open another thread:- how can I see the Ubuntu splash screen? (currently I can see the Kubuntu one)- how can I turn the splash off and have it boot in text mode?
