Ubuntu :: Randomly Turning Off Computer?
Jul 16, 2010
I have been using Ubuntu 10.4 trouble free for the last week or so with the exception of one problem. Without warning, my computer shuts off. When I turn the computer back on, it skips the log in page. The turn off is very abrupt and happens without warning. It happened twice when I first installed the OS and has not happened at all until today when it happened twice again. Is this a common issue. It seems like a very odd way for a computer to crash.

I have a problem with my internet connection. It is turning on and off all the time. I can maybe surf 3 sites without a problem then the internet goes really slow and after that I wont be able to surf at all. After a while it works fine. I can't even look on ..... videos because all of them stop at half or before. I have connected to my router through my cellphone and my ps3 and those two are working just fine.
I am running ubuntu 10.04 64bits. I don't know what network card my computer has.

I am having trouble with my computer. I accidentally deleted my python and turned off my computer. Right now I am using an old version of ubuntu (ubuntu 8.4) and would like to know how I can restore the python for my ubuntu 10.10 so that I will not lose the things that I have installed on it if this is possible.

I am in a situation at the moment which means I am going to be without an ISp for a week or two, and I can't survive that long without the intenet!!! What's more, I have 8 computers that need to connect, though not necessarily at the same time, but certainly more than one at a time. Anyway, I came up with an idea to buy a Mobile Broadband Dongle, and then share the connection via my PC. Problem is, I don't know how I would go about setting my PC to be a Wireless Access Point/makeshift Wireless Router, and sharing the connection.

I upgraded to 10.04 and it is sooooo annoying. The computer will just randomly shut off. Sometimes it will be 10 minutes after turning the computer on, sometimes 10 hours!

Randomly; my computer will freeze up. I can move the mouse but I cannot click on anything. This has happened at least 20 times today. Occasionally my computer will totally just shut down. My computer has been almost completely rendered Useless. I do not know what to do or even where to begin. The sooner we solve this problem the better. I do college online... so this has a major impact on me and my work and progress as a student.

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

The ssh server is running Xubuntu 9.04. It was working before. Then I tried SSHing today and it gave me a connection refused. The computers I've tried SSHing from were running Ubuntu Netbook Remix 10.04, MacOS, and Solaris 10. None of them would connect. The ssh server is running the latest version of openssh-server (according to apt-get install). I'm assuming something in /etc/ssh/ got changed but I'm not sure.

My computer randomly shuts off sometimes and I'm not sure what causes it. It doesn't always happen when I'm doing the same thing.I know this is hardly any info, but if someone could let me know where I can go to find logs and Also, if this means anything, to restart my computer I need to physically turn it off (the I/O switch on my PS) and let the capacitors on my board empty out before starting it up again.

I am asking in the wrong place or anything like that, I tried to understand the Tutorials, but I am only human Oh and I am not a native speaker of English, So I also apologize for that...Okay enough apologizing, I will assume that you are all nice people and wouldn't have made fun of my stupidity anywayAs I said I am new to Linux and also to my PC. I bought it a couple of weeks ago and I tried to install Windows on it, but it was displayed in only 16 colors ( I assume this is not connected to my current problem but it might be...) and I couldn't fix that so I installed Ubuntu 10.4.something( It asked me if I wanted to upgrade to the newest version...) . Since then I have been really happy, I only had minor problem with the chat software but after I googled it I found a solution and I even used the console for the first time in my life.
The problem with the chat software is back now, but I don't care about that.My Computer randomly stops working and the screen goes all weird. It switches between a mix of white and black bars, something really colorful and a black screen with text ( I have the feeling it's different text every time) I am not sure what happens after that, because I always turn it off and restart it. It won't react to anything when it is in this weird mode. I don't think there are any special situations in which it happens and I can't reproduce it, it just happens when I don't want it to happen. A friend who uses Linux said it might be a temperature problem, he only knew what I just told you. I am not sure if there is a connection between the time the computer has been on and the time it shuts off...I really like Linux and I would love to use it without ith when I said that I got my PC new ( it was used though) I was trying to say that I don't know whether this is a Ubuntu problem or not

I'm new to Fedora/Linux trying it out because I'm becoming hacked off with Windows taking so much time to do anything. The problem I have is that every now and again the computer slows down so drastically that the mouse movements are jerky, response to clicks/key inputs take about 2-3 mins to get a response and the only solution is to press and hold the power button. I'm running a Packard Bell Dot M/U. It has mobile celeron 1.3GHz 64 bit, 3GB ram. Intel wi-fi, atheros LAN (i think), HDMI output. I believe that it is v similar to an Acer Aspire 1410 (but not 100% same).

I installed Linux yesterday alongside windows vista. Everything went very smooth. I restarted the computer multiple times without issue, and the menu would pop up asking me which os to load. Everything was good. But today I attempted to boot up my computer and nothing happens. The screen just stay black. The lights come on on the laptop, but nothing else. Either I try to boot it and it goes on then off quickly, or it just sits there, still on, with a black screen. I don't know if this is related, but when I was messing around with ubuntu yesterday after I installed it, it would randomly freeze and my caps lock light kept blinking on and off. I was forced to restart when this happened and then everything would be ok.

Having just successfully installed fallout 3 (yippee), one question arises.
Is it possible to turn off (and eventually back on) all superfluous process during gaming ? As an ex-win xp user, there was an app called "game booster", i think, that did this.
The process i have in mind are things like fancy compiz settings, dockbar X, and any upgrades that might be taking place in the background.
Again, it is important that i can restart these functions after kicking super-mutant ***.

I just did a clean install of Ubuntu 11.04 on my PC. Installation went smoothly, and I can boot it and log in.
If i leave it there running, nothing happens, but as soon as i try to run an application (Firefox, Update Manager, etc), the screen turns off and I can't do anything else anymore except reboot.
I was able to apply the latest updates using apt-get update from the terminal (one of the very few apps that doesn't turn the screen off), but can't get rid of the problem, what can i do?
My PC is a Intel Core i5 PC with a Nvidia Gefore 210 graphics card.
I was able to install the proprietary drivers for Nvidea, no change. Both Unity and "Ubuntu Classic" have this issue

I'd can't seem to find a preference to turn off gedit's default behaviour of opening a new file in a new tab. I'd like it to open in a new window, so I can view two pages of code side by side. How can I convince gedit to open a new instance?

I have just finished installing 10.04 on my EEE 900A. Stuff works flawlessly insofar as I can tell. The one remaining thing I am still trying to figure out is how to turn_off the touchpad. Is this doable with some utility that I can grab from Some repo??

I have the dm1 3020 (the version found in most stores) with the ralink rt5390 wifi/BT card that so many people have been posting about, and would like to know how to make sure the bluetooth is disabled. Since I don't have any BT stuff to connect and really want to get all the battery life I can out of this thing I am using Ubuntu 11.04 with KDE, if there is a plasma widget I could use to make sure its disabled? There is no BT icon in the notifications area on the bar.

I have an issue where the screen on my laptop will not shut off with the power management tool. The Default Power Manager does not have an option for this.My screen will go blank after a set amount of time, but the lcd-backlight will remain on. I would want the power manager to shut the screen off completely (including turning off the lcd backlight) without shutting down the computer it-self. So the computer can continue to do what I left it to do in the case I forget to close the lid. With the screen shut off completely, will preserve the life of the back light and reduce power consumption.
Is there a better power manager app that will allow me to do this a tweak to the existing default power manager that will allow the functionality I am seeking? laptop was perfectly able to do this under a win-xp environment, so I know the machine is physically capable of doing this. Note: My WinXP OS and Ubuntu OS are on seperate physical drives so there is no dual boot issues. So when I am using one there is no trace of the other present

I just installed Ubuntu 10.04 64-bit version and everything worked fine so far except for the fglrx driver as it seems. I wasn't able to enable desktop effects and couldn't start games like openarena or nexuiz.
Therefore, I installed the fglrx driver from ATI's site and got everything working fine. Unfortunately it introduced a problem with vlc and the window manager in general. If I go into fullscreen in vlc it takes at least 2 seconds until the screen reacts. Also, if I tab through windows there is at least a second delay which is all very very annoying. I removed the driver again and re-installed fglrx from the repos. I now have two entries for the Catalyst Control Center (normal + administrative) under System->Prefrences which is annoying but not the reason for this thread.
The main problem remains the delay with window tabbing (with desktop effects disabled) and vlc going into fullscreen (this also applies for ..... videos which also lag in fullscreen mode).
The card is a Radeon HD 4830, processor is an AMD Phenom II X4 810.

I installed Touchpad and its says:
GSynaptics couldn't initialize. You have to set 'SHMConfig' 'true' in xorg.conf or XF86Config to use GSynaptics
I find out at this link this link that I need to create a xorg.conf file by typing:
sudo Xorg -configure
In terminal. However, when I do I get the following message, and no such file gets created.
Fatal server error:
Server is already active for display 0. If this server is no longer running, remove /tmp/.X0-lock and start again.
Please consult the The X.Org Foundation support at [URL].

I want my video card to stop processing an image to my integrated monitor and only process images to my external monitor.
My problem is that I use my Toshiba Satellite M65 (which is a laptop) as a desktop: I use an external monitor, external keyboard, and of course an external mouse. I only recently started using Ubuntu after many years of Windows XP and I just realized that both my laptop's integrated monitor and my external monitor are 'on', displaying the same image. I want my video card to stop processing an image to my integrated monitor.

If I turn off the monitors, I get a black screen (the monitors goes to power save) when I turn them on again.
I have a workaround which involves pressing ctrl-alt and f3 and then ctrl-alt f7. That usually works and brings up the graphical login-screen. And I get my session back.
But sometimes when I log in, my session is gone. It is as if I was logged out or the system has rebooted.
I have two monitors and Nvidia.
