Ubuntu :: Crashed 5 Times In The Last Hour And A Half - Constantly ?
Nov 29, 2010
I want to know what other people have done to stop their computers from crashing. My main computer has now crashed 5 times in the last hour and a half.
I am not using Compiz, and to the best of my knowledge it is uninstalled. I try not to use flash with the internet. I am using the 64 bit version of 10.04, because I want to make use of my 8GB of RAM.
The computer crashes constantly. Constantly. Usually when I am using it. I can leave it on for days without a problem; but as soon as I need to get work done, it starts crashing.
Some specs:
ASUS P7P55D Pro motherboard
Intel i5-750 processor.
evga GTS 250 video card with NVIDIA drivers (uptodate)
8GB RAM
Ubuntu 10.04 64 bit
I need a gameplan to make this computer stop crashing. how to start diagnosing the causes of these crashes.

I wish to run a cron job every half hour, where exactly do I put the job? The reason I am asking is that I am used to entering jobs into crontab, I am not used to using fedora and its cron layout.

I manage an Apache 2.2.3 web server. It stops working several times an hour, so I removed the semaphores and restarted it as a workaround, but I dont know what is causing this. Lately i've noticed that the workaround is not working at all.
Code:
0 */1 * * * /usr/bin/ipcs -s | grep apache | perl -e 'while (<STDIN>) { @a=split(/s+/); print `ipcrm sem $a[1]`}'
0 */1 * * * /sbin/service httpd restart 1>/dev/null
Below is what I can see in my error_log file.
What is the mutex message telling me. To be honest, I don't know much about semaphores nor how they work. You can see after the semaphore issue, that Apache is sent the SIGTERM signal. I have seen other posts on this topic, but not explicitly with Linux 2.6.22 and Apache 2.2.3 with a description of the issue and a permanent fix.
Code:
[Fri May 27 22:00:04 2011] [emerg] (43)Identifier removed: couldn't grab the accept mutex
[Fri May 27 22:00:04 2011] [emerg] (43)Identifier removed: couldn't grab the accept mutex

I just decided to completely switch from windows 7 to Ubuntu 10.4. I wiped windows 7 and attempt to install 10.4. it installed half way and gave me an error "cd drive disk error". So I then downloaded 10.10 and burned iso image on a brand new cd disk. Now I am trying to install 10.10 (latest version), and its stuck on Ubuntu Splash screen for last half an hour. It does not seem to be doing anything. What shud I to complete the install?

I installed 10.04 today and so far it has crashed a lot of times.It's not so much of a crash but, the screen goes blank, the top half of the screen keeps flashing with white and black lines hanging vertically.I can't do anything when this happens, I just have to press the tower, and it brings me down to the shutdown screen.

I've a very annoying(and strange) problem with hibernation. I'm using Ubuntu 10.10.
It's been a month and the hibernation works exactly in the following pattern:
success->fail->success->fail->......
By success, I mean the machine hibernates OK and wake up exactly as before hibernation.
By fail, I mean the machine go to sleep and when wake up, all applications are gone and the login screen is displayed. I think gnome desktop has crashed in such cases.

I have just installed (after a series of crashes during the install) Fedora 15. I also have Ubuntu Natty installed and use it primarily but I wanted to reach out and try new distros.I've wanted to try Fedora and finally got enough nerve to try. Installing it crashed for no apparent reason several times.ehow it installed and booted right to Fedora.However, when finally figuring out how to run the updates, I began to have the same problem.(Someone elsewhere suggested trying to update through command line--which I did finally though I had a few crashes doing this).
Now I am logging in and then it will just inadvertently crash. I could be in firefox, or using terminal, etc. There doesn't seem to be much rhyme or reason to why this is happening and I feel frustrated. I really want to test out Fedora (it looks so nice!) but can't manage to stay afloat more than a few minutes. I might also mention that this does not happen in Ubuntu at all so I can't account for the issues. I have much to learn but I feel a bit intimidated by Fedora because it's so new to me.

I recently decided to try KDE4 and would like the change the clock on the panel to display 12 hour format and not the default 24hour format but i can not find where to change this option currently the clock looks like the attached picture. Gnome has this option and I would like to see it in KDE if it exists in the default clock. I am willing to replace the default KDE clock with a seperate widget if one exists for this.

I just upgraded from 9.04 to 10.04 and so far I have those problems:
1. Before, everything in my system was in English. Now, half is in English, half in another language (PCManFM, some menus etc). I tried setting up Language Support but it changes nothing.
2. Cursor themes work only when hovering the mouse over "X" buttons in the right top corner of the window. As soon as I move the mouse somewhere else, it goes back to default cursor theme, even though I tried selecting 5 different themes - same result.
4. Hibernation don't work anymore. s2disk saves image to disk and then it resumes it but computer stops on text message along the lines of "Resume completed successfully".
5. Changing volume with keyboard shotcuts no longer works.
6. Smplayer does not display picture anymore when playing movies. The view is just empty. I can only hear the soundtrack. It is using XV filter.
7. PCmanFM that used to worked flawlessly, now after going into 1 or 2 subdirectories stops reacting to clicks on file/folder list. Need to open new instance to be able to do anything and this again would become unusable after visiting 1-2 folders.

The only vommand thw actualley work is reboot. I searched for this and read a grub guide but it did no good.

I just switched over to Lubuntu, and so far, it's been great.It's rendering quite well with my laptop, even though the fan is constantly running.I've had some small annoyances that I haven't been able to figure out. How do I get the power button and/or other related actions to the 'start' menu? Is there a way to drag and drop applets like in Ubuntu? How do I setup default brightness like in Ubuntu? How do I change the time to normal US time (12 hour instead of 24 hour)How do I change the time to a 12-hour instead of 24-hour?Is there a software center?

I need to change the time displayed in the task bar from a 24 hour clock to a 12 hour format. I could not find the relevant settings in OpenSuse 11.2 and same is the case for 11.3 as well.
how to make the change? I have tried System Settings ---> Computer Administration ---> Date & Time; but I was not able to make the desired change.
Similarly, I have a digital clock widget that shows GMT + 5.5 hours and I need to change that to 12 hour format as well.

My internet disconnect mabe every second hour and I have to restart the Ubuntu to get internet again. This started to happen when I bought a new wireless card called NETGEAR WG311v3. The live CD didnt have the drivers for it so I had to download XP drivers and install it with ndisrwapper.
So my question is how do I fix it? Do other network drivers crash with my current one? If so how can I see wish one to remove?
Note that my card works fine with XP on same computer.

Installed Lucid netbook-remix on my Aspire One with SSD and 3 cell battery last night. Under 9.10 I got 2hr 15mins with wifi and up to 3hr without wifi. This morning on the train to work I booted the new release only to find that without wifi I'm now getting only 1hr 20mins battery life (fully charged battery). I have the brightness turned down low to try and save a little power but it makes no difference. What can I do. As this is a netbook-remix release having just over an hour of battery life is plain awful and impractical.Any suggestions to increase battery life?

Recently moved into amazon's ec2 cloud and noticed our server time was in UTC where we use EST. I did some looking around, and changed using the following;
Followed up setting the correct time using the date command with the correct time, then date showed;
Now, that is correct, but if I do an ntpdate pool.time.org or any other time server, the offset is huge and the date moves back one hour. Is this a daylight settings or something I am just missing?

I am quite new to this ubuntu business, but i like what I'm seeing so far. Well, almost everything that I'm seeing. I seem to have run into a tricky problem with xubuntu 10.04. I was in the process of customizing my desktop appearance (via Xfce4 Settings manager), and I found a nice theme to go with (dusk I think it was called). I then went on to change the window settings and starting from the bottom most option I browsed the various styles. After a few of these my computer decided to log me out quite suddenly, and I was prompted to login.
This is where the problem is: I type in my password and it logs me in for maybe a half a second only to log me out again. No matter how many times I put in the password I keep getting logged out. So now I'm running xubuntu 10.04 off a pendrive that was used in its initial installation. Is there any way to log back in and stay logged in long enough to undo the window styling at fault? I had put in quite a bit of work migrating files, installing all sorts of things and setting up fancy launchers, and I would prefer not to have to redo it again.

After daylight savings time, my squeeze installation's clock failed to adjust. I've tried to change this in the bios, but it always resets itself.
Is there a way to force-change the time?

I have a script that I want to run for one hour.
I used to use doalarm to make it run for one hour then stop but it is not working consistently so I need another solution.
How would you make a script run for one hour then stop?

I have a Trendnet TEW-649UB Wifi N dongle, and I'm using the latest Realtek firmware downloaded from their website. It works ok, but everytime, after an hour or two, the blue light turns off and the dongle stops working. I have to unplug it and plug it back to bet my network back up.

I've managed to install the 32bit version on my laptop with little issue, and I'm really liking the Unity interface. There's a few issues around customisation and minor usability quirks, but from my experience with things like KDE4, I'm guessing it's only time. Anyway, I've been having major problems getting the 64bit version running with my Desktop. I have 8Gb of RAM in that, so it's not really an option to use the 32bit version. The Installer crashes constantly, but I was able to upgrade from 10.10 using update manager, but unfortunately Natty is no more stable than it's installer.
While logging in, or shortly after, the machine will crash to a text console displaying a Kernel Panic message. There's also messages indicating a problem with the CPU MCE. I've tried setting various kernel parameters at boot, such as nomce and nomodeset, these have extended the time the machine is up before crashing out, and removed the Kernel panic message, but not the crashes. I'm guessing the MCE messages were unrelated or a symptom in this case.I've done a huge amount of searching, and found no suggestions that I haven't already tried. Running Ubuntu 10.10 64 bit the system is rock solid.

I think I have found the problem to my Ubuntu laptop locking up, and it is most likely overheating. Is there any way to keep the CPU fan spinning at 100% constantly? I tried setting it up in the BIOS but it is an old laptop and I can't control it from there.

I have a machine currently running Debian Lenny on which I would like to run Ubuntu for the driver support in its newer kernel. However, I did a test boot from the installation CD and it appears to be running at less than half its rated speed. This is the output from the Debian kernel:
brendand@kant:~$ uname -a
Linux kant 2.6.26-2-amd64 #1 SMP Wed May 12 18:03:14 UTC 2010 x86_64 GNU/Linux
brendand@kant:~$ cat /proc/cpuinfo
processor: 0
[Code].....
Maybe this is some sort of power save bug where the CPU speed is incorrectly scaled back. Has anyone else encountered this problem? Should I report it as a bug, and, if so, how do I do that?
