I am on 64-bit Natty and for the first time since my install a month ago, I have had a system hang requiring a power-off restart. It happened yesterday and a few moments ago.My question is that I want to troubleshoot this myself and wonder if the activities that my system were running just prior to crashing are recorded in a log file somewhere.I used to look int /var/log.messages or /var/log/boot, but this was in the Maverick days.
I"m a newish Ubuntu user, but have been running some flavour or other for the last 5-6-7 years. Anyway, I just recently installed Maverick and have to say it's polished compared to the last version I tried ( maybe 6? ).
I am however having a frustrating issue while surfing the web. After a 2-3 minutes using firefox, 5-10 minutes using chromium - the whole system seems to lock up solid. The mouse/ keyboard no longer respond. I've read through a few log files and nothing seems to stand out, though I may be looking at the wrong place. I plan on running some system monitors, and top when I get home to see if they show me anything. Just thought I'd come here to ask for any other things to have a look at.
I have Ubuntu running on a Compaq desktop. Version 9.04 ran great but since upgrading to 9.10 it intermittently locks up. There is no rhyme or reason to the timing. Sometimes it is immediately after logging in but usually it is after the system has been running awhile. Sometimes it happens when I'm actively using it and sometimes when it is idle. It has never happened at the login screen, no matter how long I leave it.
Note that it is not a complete lockup. The mouse cursor moves, but no longer functions (i.e. you can't click anything). The keyboard does not work at all. For example Ctrl-Alt-Backspace and Ctrl-Alt-F5 do nothing. Disconnecting and reconnecting the mouse and keyboard does not help. Also, I can still access the system over the network using SMB and SSH, which leads me to believe that X or Gnome is where the problem lies.
Here are the troubleshooting steps I have done so far. As I said I can access the system using SSH, so I logged in and ran "top" to view CPU utilization. I found no process using more than 1% of the CPU. Also I examined the messages log and found "segfault" errors related to libc (?), USB and my keyboard, so as a test I traded my fancy wireless keyboard for a generic one. That has not helped. I'm not sure where to go from here. I've examined other logs but it is all Greek to me. There are entries that sound as if they could be errors but I'm not sure and the times of the errors don't match the times of the lockups anyway.
I've tried searching all over the place, and I'm drowning in outdated and contradictory information. I have a brand new Netgear WiFi PCI adapter. The exact model is "WN311B-100NAS N300" The related output of lspci is
Module Size Used by lib80211_crypt_tkip 17387 0 wl 2568244 0 lib80211 14991 2 lib80211_crypt_tkip,wl
[code]....
So, I know it's using the BCM4321 chipset and wl driver. Ubuntu detected this card without any trouble, and I was able to use the "Additional Drivers" application to get it running before disconnecting my ethernet.
The card works well, and is very stable until I try to download a file larger than a few MB, or try to play a video stored on my home network. As soon as I try either of those, my computer locks up hard. No error messages. Just a hard lockup that I can't get out of with anything short of holding down the power button on my case until it cuts the power supply.
I had this problem at times with 11.2 as well; I use GNOME. I have intermittent lockups when invoking the screen saver either while idle or soon afterward while using Firefox; problem seems to not show up if I do not use a screen saver when idle.
Since upgrading to lucid, I have been experiencing regular system lockups. About once a day, my X desktop will disappear and I'll see a TTY with a few old console messages and at that point everything is completely frozen and I must hard reboot.
I have checked out various logs in /var/log and found nothing at all that indicates the system knew anything bad was happening. What is the correct approach to try to narrow this down?
it only seems to happen when im using wicd to change wireless access points several times in a short time span. i havent done anything out of the ordinary, installed packages off of sbopkg, and built my own kernel, but this happens in the stock kernel toothe following is what appears in syslog each time it happens
Code: Mar 7 13:12:14 null kernel: [ 1.714177] WARNING: at arch/x86/kernel/hpet.c:404 hpet_next_event+0x5f/0x81() Mar 7 13:12:14 null kernel: [ 1.714969] Hardware name: 3241
I have a fresh install of CentOS 5.5 on small thin client system with a 80G HDDs, 1 GB ram [URL], I have run into an issue where the system just locks up and freezes and I can no longer access it, cant ping it, cant use webmin and cant view its web pages. The system seemed to be running fine unitl I left it to do some updates via webmin as it informed me there were 118 updates. I really only use the system as a LAN captive network server, and it is currently in the testing phase for this setup. The install went on with no issues and it ran fine, but now every so often within 12 hours it just locks up and I have to reboot. kdump shows no logs so I am finding hard to work out what is going on. but have installed it on 5 of my servers 4x ibm x335 and this . I intend to use the mini server for a captive portal system displaying advertising and promotions to wireless clients.
I recently switched to Ubuntu and I'm loving it, except i am having sound problems with both my laptop and my desktop.My laptop is using an internal microphone (it is a Toshiba Satellite P500) but the mic is not recognized, I hook up my M-Audio USB audio interface which has my studio mic connected to it, it gets recognized as an input device but it doesnt recordSame thing on my desktop, it gets recognized, doesnt record.My laptop is 64-bit and my desktop is 32-bit, both have Ubuntu 10.04
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.

wat is the advantage of introducing softlock feature in rhel? How user/admin will be benifitted if softlockup events are occoured? on the contrary, server dies if softlock happens.We hardly can take some preventive action against softlockups, but most of the times we are not able to do anything about softlockups?
For about 3-4 weeks, my file system used space was growing and growing. After some days, I decided to analyze the file system in order to understand what is going on. Well, the results returned that the log files at /var/log ( especially kern.log, syslog and messages ) were the log files that were sucking the free space. I searched if this was some kind of bug but it turned out that if these files are growing, the problem is in the records.
So I picked from the tail of the messages log the last 50 lines and I saw this:
I'm running Ubuntu 10.10 in a Samsung R510. I've tried to record sound with an external microphone and there have always been a permanent noise accompanying it.I thought it could be the internal microphone, that's causing the noise, but even when I disabled it the noise remains. Or maybe I didn't disable it the right way !
I have installed the fglrx driver from "Hardware Drivers" and it runs fine, until I launch gnome3 or gnome-shell, it then just locks X (its not hard locked, I can CTRL + ALT + 2/3 etc out) but I cant do anything else.
If I use the mesa / xorg driver its fine.
The trouble is I play one game, and I need the fglrx driver for that game, the mesa one corrupts the 3d engine
It wouldnt be a pain, but i am one of the few who seems to find gnome-shell an improvement, and I get really frustrated when it wont work.
Any idea's on what I can try, other than hopfully having a working system when ATI launches the 10.10 driver on its website (although the leaked rc had the same issue) I only recently got a ATI card so I am pretty new when dealing with the ATI cat's.
I tried ubuntu 10.0 yesterday (running from my usb pen) and I liked it. A lot. However, there are a few issues that i need to know if there's any way to solve them, before making the transition: Keyboard keys are swapped; I mean, if I press alt+(anyNumber) I get another character. Why does this happen?-I develop a lot of code in VBA; I tried to record a macro using Open Office Calc, but I got the impression that the code used in the recorded macro is slightly different.
Using Debian Lenny I recorded a wav file with Audacity to burn to a cd with K3b.The problem is when I played the cd with KsCD; it wouldn't stop when it got to the end; it just kept studdering. I didn't have problems using KsCD to play CDs I had ripped and then burned with K3b.Is this a problem with KsCD, or do I need to do something when I finish the file with Audacity?
I recorded some clips on the internet through the sound card withAudacity. I exported the recording as a wave file, and burnt it to a CD. The problem is stop playing. It comes to the end and just repeats the last fraction of a second over and over.I used K3b to burn other audio CDs that I copied and didn't havea problem with KsCD playing them. Is this a problem with Audacity,KsCD or did I do something wrong?I recorded the file; saved project and then exported as a wave file
I don't know if these are related, but I have had occasional lockups, where no input has any effect and then it shuts down, and am usually unable to resume from suspend on closing the lid.
Here are the specifics. Thinkpad x120e, AMD e-350, ATI radion 6310 graphics, Intel 320 series SSD 80 GB, no bluetooth.
The ethernet and wireless cards, as given in lspci, are
I am having some problems with recording with my laptop. When I try to record something through the laptops mic, usb webcam mic or with desktop recorders audio record feature all playback is too fast (sounds a bit like alvin and the chipmunks :L ) Is anybody else having this problem, or even better know how to fix it ?
Sorry if this has been asked before, I'm running 10.10 and had never tried recording before I upgraded to 10.04. I had the same problem in 10.04 though.
I want to measure the time it takes to execute a C function. The question is which is the best method to record time. After a lot of searching online, I found two ways [URL]:
a. using clock_gettime(CLOCK_MONOTONIC, &t) b. using TSC
I call the C function 50 times (recording the time it takes for each call). The average is found only for the last 35 calls.
Using (a), I get:
48345 us 28350 us 28379 us 27716 us
[code]....
Average time for the last 35 loops: 121450.47 microseconds
Average for the last 35 loops: 27236.66 cycles What could be causing the strange value of 3322259 us in method (a)? I could just use method (b) but I would like to know what is going on here... Btw, I am using a desktop - with Linux debian 2.6.26 #1 SMP.
I have a lot of recordings on my mythtv box.i can see/play them fine within the mythfrontend interface, and mythweb loads almost all pages ok (including schedules, guides, etc.), but when I click on 'recorded programs' at the top, Allowed memory size of 33554432 bytes exhausted (tried to allocate 88 bytes) in /usr/ share/ mythtv/mythweb/includes/translate.php on line 142.I've had this error before, and it went away when I purged my list of recordings.
I'm trying to record video off my webcam, and tried two different programs - cheese and wxcam.
I honestly didn't have much luck with cheese - it seemed to work fine, but when it came time to record video, the frame rate dropped to a ridiculous level, making the video completely unusable. I could wave my arm in front of the camera, and it might pick up one frame of that.
Moving on, I tried wxcam, which I like a lot.. however, when I record video with the xvid compression, they play back considerably faster than they were recorded.
I have recently installed OpenSUSE 11.3. I can play audio files, but there is a problem recording, namely the recording is way too slow. This was tried 3 ways: in Audacity, in Skype (making a test call), and using the arecord command in a console, as root. To make the playback sound normal, I tried taking the already-recorded file and speeding it up in Audacity. It was necessary to speed up the recording by 50%. I've tried updating alsa and other suggestions which I could figure out, and run the scripts for diagnostic information. BTW, I'm using a headset plugged in to standard 1/8 inch mic and speaker jacks, not a USB headset.
I am trying to record using a microphone on a machine running Fedora 14. The microphone itself seems to work fine when plugged into a Windows laptop, and the Linux machine is able to play sound just fine. However, although I can record using the microphone (using arecord or audacity, for example), the recorded audio is super, super quiet. I have run alsamixer, and experimented with every capture source. Anything which had any effect (using arecord -vv to see the dynamic sound level) has been turned up to 100%. Still, recorded audio is barely audible.
I have run: yum reinstall alsa-utils alsa-plugins-pulseaudio alsa-tools-firmware alsa-firmware alsa-lib But that made no difference. I ran alsa-info, and the output is here: [URL]. Why my recorded sound is barely audible? My next step is probably going to be to boot to Ubuntu, just to see if it has the same problem.
Maybe I'm not using the right search terms, but I can't find anything on this. I have a setup of Slackware with Asterisk and FreePBX. I am recording calls on demand and can get to the recordings from the Call Monitor (web interface). I would like to be able to access the recording from the phone (Aastra 57i), much like a voice mail is accessed.
If I initiate a file copy of more than a couple of GiB, the PC goes into a dramatic slowdown. Even selecting a different subdirectory through Nautilus can take 30+ seconds.Now, whilst I appreciate that file copying puts a load on the bus, DMA and, to a certain extent, the CPU, it seems unconscionable that it makes the PC effectively unusable until the copy has completed.Is there any way to (practically) lower the priority, or similar, of the copy process so that one can continue to use the platform during large file copies? Right now, I end up using a laptop adjacent to the PC whenever I have to copy a large file. This, for a mainstream operating system is, frankly, ludicrous.I'm aware that I could run Nautilus 'nicely' but I don't want to make changes which would compromise other aspects of the system. It would also be pleasant, for a change, not to have to read a couple of telephone directories of technical documentation in order to resolve the problem myself. This must be a general problem and, in my view, something which seriously compromises the usefulness of Ubuntu given the sizes of contemporary drives and files.

My wife is taking an online language course that requires Windows in order to record and playback speech (for pronunciation training). I decided the easiest thing to do would be to clone a VM I use on my machine for tasks that can only be accomplished in a Windows environment. I did so, and successfully installed the speech recognition utility on the Windows guest VM. Unfortunately, although the microphone works just fine--I can hear my voice in the headphones--no sound is recorded by the speech recognition utility. Just to be clear, the microphone is fully functional under GNU/Linux. My wife has been using Skype without any issues at all. That is, Skype used to work. Somewhere during the course of trying to resolve the voice recording problem I managed to break Skype. I have no idea how.
It's a long story, but I'll try to be as brief as possible. When I could not get the VM solution to work properly, I thought maybe the problem was with the VM, so I checked the original copy on my own machine. No problem there. Windows sees and hears the microphone just fine (using the testing utility under sound configuration). So how is it possible that the microphone doesn't work in the cloned VM image? Before you stop me, allow me to note that both machines have identical motherboards, and both are configured to use the onboard sound. Sound works on the Linux host and the Windows guest VM. Both sound and microphone work in the original VM image on my machine, but only sound works in the cloned VM on my wife's machine.
If you've followed me down the rabbit hole this far, please continue with me a bit further as things get stranger and stranger. After triple checking all the setting in KMix (I'm running Squeeze/KDE on both machines) to be sure they were identical, I noted that I was unable to view/add/enable the "channel" option on my wife's machine. Why, I have no idea. As I said, the machines are identical as can be both regarding hardware and software. Out of desperation, I decided to set up an account for my wife on my machine. I created her account, made sure she had the necessary audio permissions, then cloned my VM to her account. Same problem.
I would love for someone to point out what I'm missing here. Same hardware, identical VM (clone), same permissions, same sound configurations in KMix and under the Windows guest VM. How is it possible for the microphone to work for me, but not for my wife? Is there some mystery configuration file somewhere that has magically been altered for her account alone? The worst part about this entire process is that I've broken my wife's Skype, which is a big deal seeing as we live in a tiny country in the heart of Africa and cell phone communications are very expensive.
Howdy, I just installed a dual boot on my Acer Aspire One and it runs great. I was wondering is there anyway to access the files from either side? If so I can't see the XP file system from the Ubuntu system.
I read that Natty will use Unity as the preferred desktop environment, together with Compiz. I found that on my system Compiz - while very neat - will cause instability so I'd rather not use it. How would the desktop stack look for a user not wanting to run Compiz under Natty? Can I use Mutter with Unity? Or maybe I should replace Unity with Gnome? Will my Ubuntu like this (replacing Unity with Gnome)? Will Ubuntu make it easy for users to dump Compiz if they want to do so?
