Ubuntu :: HP Computer Heating Up Really Quickly For No Reason

Jun 21, 2011

I bought a new Hp Pavillion DV6T. For the most part, everything worked right out of the box with ubuntu, but the computer seems to be heating up really quickly for no reason whatsoever even if I'm not doing anything intensive. Why this is happening. The fan always seems to be running at full blast. I logged onto windows for a minute to see if there was any difference in heating between the two OSs and windows seems to run much cooler and much more quiet. On a side note I'm thinking of returning the HP and buying a dell XPS 15. I hear they are more compatible with ubuntu and are better built.

ATI Radeon 6570 1 GB graphics card

Hardware :: USB Thumb Drive Connect With Computer - Quickly Change What Was On Screen

May 9, 2010

Can Linux emulate a USB disk? Why would you want to do this you ask? Say you have a digital picture frame that uses a USB thumb drive you could connect your computer to it and quickly change what was on the screen. I realize you need some special hardware for this as both the PC and the frame would want to be USB masters. But there are USB transfer cables you can buy on-line that do USB master to master connections.

Ubuntu :: Computer Shuts Down For No Reason

May 28, 2010

I installed ubuntu 10 yesterday and I have a real frustrating problem. It shuts down for no reason at all, at first I thought it was because I was not using it (power management or maybe because of the screensaver) so configured it to never put it to sleep or shut down, and disabled the screensaver but it keeps happening. This is actually the second time I'm writing this post, because it suddenly shut down again while I was writing this before submitting it. I used to never have this problem before when I was using windows, so the problem must be something with Ubuntu.

Could it be something with my gfx driver? I tried configuring Fluxbox to use my second screen as an extended desktop but couldn't get it to work except with Gnome. If I do "fglrxinfo" I get a segmentation fault, so I messed that up but I'm okay with that because everything is working like I want it with Gnome. One weird thing I've noticed is that ubuntu once said (when booting) that it couldn't find /dev/null...? Should I just try a reinstall? I'm on a quad core with 2GB ram and an ATI HD 4870 2gb graphics card.

Ubuntu :: ATI Catalyst Installation - Over Heating And Battery Backup

Nov 22, 2010

To begin with i have a Sony Vaio VPCEB24EN Laptop with configuration

Intel core i3 Processor
3 GB RAM
ATI Radeon HD 5145, 512 MB

Installation of Ubuntu 10.10 Notbook edition make my lappy extremly hot in comparison to Windows 7, which includes degrading my battery performance from 3 hours to 45 min. As my CPU uses is normal, i deduce that my Graphics might be the cause of the heat and power consumption. Tried installing proprietory drivers from Get Software -> System -> Additional Drivers, which maximized the problem. My screen keep freezing now and then. So i uninstalled the driver and downloaded ati-driver-installer-10-11-x86.x86_64.run from ati site. While install it has issue of its own. The text written in the installer is invisible. [A print screen is attached]. This is to mention that the core fonts are installed in the system. I shall be glad if anyone have the solution for my problems

1. Over heating and battery backup issue.
2. ATI catalyst font issue.

Software :: Turned Off By Itself - Suspect Over Heating?

Aug 27, 2010

I have an office workstatation that I installed with linux and ran a 8-core job. It is expected that the job to finish in 6 days but then it stopped after 2 days. The reason is that when I came to office this morning the workstation is completely turned off for some reason. Since the air-conditioner is turned off in the office overnight, I suspect the temperature is too high for the cpu. Is there a script to output the temperature to a file periodically so that I can pinpoint the exact cause of the shutdown ?

Debian Hardware :: CPU Heating On Toshiba Laptop

Apr 16, 2011

CPU fan apparently is not working with Debian (or Kernel, I don't know who's responsible for ACPI devices management. ).After setting up lm-sensors to show core temperatures, and running a simple "while(true);" C program, I noticed the fan doesn't turn on until the temperature reaches 80 degrees Celsius, and when it does, it runs at what appears to be full speed (VERY noisy). Also, it stays turned on at that speed even after temperature gets below 35 degrees Celsius. The only way to turn it off is to put the computer to sleep and wake it up again, but if I do the same procedure, it happens again.

I think it is related to some compatibility problem with ACPI devices because when I turn on the computer, I can't get the Fn keys to work, but after I suspend and wake it up, I can control the brightness using the Fn key and use the Play, Pause, etc. buttons. I read this has something to do with ACPI issues, the same as the fan control issues, because "try to suspend and wake up the computer" is something people usually tell to others with this problem (I assume just to confirm the diagnostic).Everything works fine on the pre-installed Windows Vista that came with the computer. It's definitely a compatibility problem.

I've read a lot in forums, even here, but I couldn't get any solution for this. I installed toshset but asks me to enable a Kernel module which I have no idea of how to load. I have no idea of how to load a Kernel module in fact.Also, I didn't want to believe, but I read there's no solution for this (at least, not one which doesn't involve a lot of knowledge on the matter).I'd like to stay with Debian, so I'm doing my last try here before installing other Linux Distro. I hope this problem is about Debian and not all Linux distros.My laptop is a Toshiba Satellite L355, Intel Pentium Dual Core T3200. I bought it in the end of 2008, so it's kind of old.

Ubuntu :: Save Power And Avoid Heating By Powering Server Off Durring Day?

Jul 5, 2010

I have a server that only runs durring the hours the house is asleep, to avoid bandwidth hogging. I know there are ways to prevent bandwidth hogging, but I figured I'd kill two birds with one stone. My other goal is also to reduce power and cooling costs. My two computers between them make a very nice space heater in the winter, in summer they make it sweltering in my room.I'm sure it would be trivial to get the sever to power itself off every morning, but is it possible to get it to power itself on at bedtime? If not, I do have Wake on Lan working, is there a windows program that would allow me to send a wake on lan signal every day and then shutdown windows

Debian Configuration :: Dell Studio 1569 Heating Up And Battery Life

Feb 24, 2011

First issue is, now that I am running Debian "Squeeze", my laptop runs much hotter than before. Its definitely hot on the very bottom compared to when running Windows. Once the system begins to heat up, the fans start spinning faster, the system gets louder, etc.

Second issue is battery life. I am able to get 5 hours out of the laptop in Windows, but maybe 2.5 hours in Debian. I am assuming that these two problems go hand in hand. Now from experience with PC hardware, I know that the newer chips scale their frequency and voltage depending on demand. I don't think the computer is doing this correctly when running Linux.

By running
cat /proc/acpi/processor/CPU0/throttling

I see that the CPU(s) are in T0 state (or 100%). Manually setting the frequency doesn't change anything either (via the gnome applet). Am I diagnosing this correctly?

Ubuntu Installation :: ASUS Netbook Heating Up When Using Netbook 10.04

Apr 30, 2010

I installed Ubuntu Netbook 10.04 and immediately noticed the keyboard of my eeepc 1000HE was abnormally warm. Since I dual boot XP I booted to XP and found the fan running faster to compensate for the previous heat. This did not happen on Ubuntu-the fan just was barely running. I had to place the side of the netbook in order to feel the fan running. I issued "sensors" in terminal and it showed 67 degrees C for the cpu temp. Is the latest Ubuntu such a resource hug that it heats up the CPU?

Ubuntu Multimedia :: Everything Plays Back Too Quickly

Feb 12, 2010

when i play a song in banshee, or a videos video, i get no sound at all. however, in banshee 1 3 minute song will appear to play in about 20 seconds (the progress bar speeds along), and videos videos play back in ultra-fast motion with no sound. weirdly, when i go to system settings -> multimedia, and click test on the default sound device, the kde login sound plays back fine. this worked when i first installed; does anyone know what's going on here? i think it may be a problem with gstreamer?

Ubuntu :: Badblocks Reading Drive Too Quickly?

Sep 11, 2010

I'm running badblocks on some new disk drives just to be safe before my return period expires. I'm running the command

Code: sudo badblocks -b 4096 -p 4 -c 65536 -w -s /dev/sdb1 on an empty partition taking up the entire device. I am getting the following output:

[Code]...

1) When it gets to the "reading and comparing" phase, it seems to complete in <1s. I see other posts where people say this takes them as long as it took to write to the drive. I don't see any mention of this being quick, so I'm just afraid that badblocks is being denied read access or something.. Anyone familiar with this behaviour?

2) Obviously since it is on a sixth pass, badblocks thought that it found new bad blocks on the second pass (or later). When I check SMART, though, the drive has not re-allocated anything (despite having plenty of spares)... Doesn't this seem odd? Is there some reason why the disk would not step in upon a write fail? In fact, I thought a write fail should be transparent... Which makes me wonder if question 1 (above) is causing this...

Ubuntu :: View 11.000 Text Files Quickly?

Oct 13, 2010

I need to view 10.858 text files by this friday to see which ones I need (searching file contents is not a solution), I was wondering if anyone knew any way/program to quickly view them as if they were, for example, images? And, optionally, to be able to save them to a different location from there? It doesn't necessarily have to be for Ubuntu as I also have WinXP and Vista, but it would save me having to transfer those couple of gigabytes to another computer.

Ubuntu :: Quickly Add Swap Space Over Command Line?

Working with a scientific code that uses more RAM+swap then i generally have (system has 12GB RAM + 24GB swap, but this thing is crazy)It's kind of a one use problem, so I'm not looking to get more RAM, is there a quick way to add more swap space (not on the swap partition, because i have that set at 24GB) so that my system can use it immediately?I don't want to drive up to the office tonight to get this fixed, so a command line setup would work best.

General :: Ntpdate Getting Out Of Sync Quickly

I'm trying to sync the clock of an ubuntu desktop with the network with ntpdate -u <ntp-server> and in a matter or minutes it's growing an offset of a few hundred milliseconds and even more than one second. Is there anyway to guarantee that the time keeps synchronizing with the network more frequently? does it make sense that the offset grows so fast? Am I doing something wrong?

Software :: How To Quickly Mark Files

Jul 10, 2010

Using a GUI file browser, I would like to be able to mark files with an emblem or something similar as quickly as possible, with a single click. I'm currently using Gnome Nautilus in my Ubuntu 10.04, which doesn't seem to offer the functionality. I'm not keen on trying the extension Nautilus-Actions as it doesn't seem to be open source. I've set up some scripts though, but accessing them through the pop-up submenu is just clunky enough to still have me searching for a faster solution. Does a file browser exist that would let me set up a toolbar button for marking files? Or a button for launching scripts, which would amount to the same thing.

Ubuntu Networking :: Way To Quickly Share Files With Windows Clients On The LAN

Dec 13, 2010

Here I am editing /etc/samba/smb.conf and trying to remember what I should chmod the directory and the files to, then I think to myself there's probably an easier way. That way should be clear to the user.

There's dropbox and Ubuntu one but these are something slightly different, these sorts of things involving a cloud service or something needing to download to Windows clients, which is not what we want if we don't have an internet connection. So, is there a better way? Something to aide making smb.conf and permissions perhaps?

Ubuntu Security :: Transferring Sensitive Data Quickly And Securely?

My company needs to send sensitive data across to another company, 800gb of .dpx. The way I have thought of is:
E-Sata/1TB WD black.
True-encrypted/ hw accelerated aes (3x machines being built with 2600k)
Sha1sum on each file.

The main goal is to make sure that
1. The files that were transferred off the server onto the drive, are exactly the same.
2. Secure.
3. Fast.

Ubuntu :: Quickly Remove Multiple Related Packages From Command Line?

Feb 15, 2011

Is there any way to quickly remove multiple related packages from the command line instead of having to enter the name of every single one? I am trying to remove OpenOffice from my server running 10.04. It would work nicely if I could get a list of packages without line breaks, such as the list displayed by aptitude when upgrading. That way I could just paste the package list into the terminal. However, "aptitude search 'openoffice'" dumps a long list on many lines that cannot be used that way.
