Ok so've installed ubuntu. Looks great, but there's one problem: fan is really noisy, all the time, even when I'm not running any app...
I've changed the power preferences, and activated the option: "Spin down hard disks when possible", but didn't have any effect.
I have a toshipa satellite L-500, and used to use toshiba eco utility for windows but they don't make that for ubuntu.
I have recently installed 9.10 on my pc. All seems ok except there is a lot of noise coming from the tower now. It sounds like one of those old dial up modems that computers used to have. It starts right after the ubuntu starts. On the first install I had vertical lines on the screen that would become more broken the busier th computer was.So I installed again selecting to use lower graphics mode before installation. The lines have gone but I can't use avant window navigator as I get an error message saying the screen hasn't been composited. It invites me to use compiz to do this but a really can't see how.Also it won't let me select visual effects in appearance preferences. The most annoying thing is the noise like an old modem is constantly trying to connect to the web.

Both times I've had this really loud sound which I'm guessing is the fan going a bit mad. Is this related to a newer kernel or something? Is it dealt with easily? This is a Toshiba Equium laptop from 2 1/2 years ago. I've got the Powersave setting on now in the hope this might stop it happening while I'm trying to read up on this and get advice.
After all the observed Linux progress since I've been using it I'd be quite annoyed if something botched in the OS kills my laptop. The computer got quite hot, even though its feet are rested on a wooden board that normally prevents this.
I'd like to know how to get off that noisy static sound from my microphone, because when I use my microphone on programs like skype, the sound static annoy the people who is trying to hear me.I've made some tests using audacity, and I can see that my mic sound is reaaly noisy.On my windows system with the same hardware, this doesnt happen.I'd be glad (and my friends too ) if I could solve this problem.

That noise stays whether I play music or not.
The noise doesn't exists in Windows 7. (I have dual-boot configuration)
Details:
Using openSuSE 11.2 x86_64 (KDE)
Using Creative Labs Inspire 2.1 2500 Stereo Speakers
Code ...
BTW, I can't find the Sound module in the Hardware section in YaST, as written here.
I have installed Kubuntu Lucid on my Samsung NB30 netbook. Got everything working, but the disk access seems extremely slow and noisy. Whenever larger files are being processed (software installation), the disk makes a kind of rattling sound - looks like the head is moving back and forth between two or more locations. The disk seems o.k. so far - no io errors under Linux and Windows XP boots without problems.

View 7 Replies View RelatedI've just installed Debian Wheezy on my old Toshiba Satellite A10 (Intel celeron 2.20 GHz, 1GB Ram, 30 GB hard drive) and tried to connect to my home wifi network with a usb wifi adapter (Hamlet HNWU254G). lsusb in terminal says it is Ralink RT2501. Ethernet worked fine, so I installed firmware-ralink package, the adapter was recognized and I was able to connect.
However, I heard quite frequently a strange whistle and realized it came from the usb wifi adapter; it also got very very hot. Other strange thing: the computer some times freezes: screen flickering, loss of control of mouse and keyboard, need to shut down with power button.
At first I thought it was the video card not being powerful enough for Gnome (even classic), but then I installed Xfce4 and nothing changed. Instead, when working offline, freezes happen less frequently (but still happen).
I've tried the usb adapter on another laptop with wheezy: it gets hot, but there are no whistles and freezes.
I've been trying to set up a FTP server for some quite some time and i keep running into problems. I'm trying to set it up via gadmin- proftpd but even with that i cant get it to run. Can anyone point me towards a good how-to or just help me out? I'm kinda new to Linux and this is my first go at servers so i really have no clue here.
View 9 Replies View RelatedI have the latest release of Lucid Lynx installed. I want to try out audio recording on Linux so I want to know if it's possible to use a real time kernel with Lucid. So I installed the 2.6.31 real time kernel. It shows up in GRUB, but when I boot it gives me the message:
mounting none on /dev failed No such device
It then takes me to the login screen, and once I enter my password it just takes me back to the login.
i have two bash script files namely, "a.sh" and "b.sh". Both the files contain some commands to run, how can i actually run both files at the same time, instead of running the file one by one?

In any case, I'm basically trying to run programs remotely at work (from home) that will run for a long time. I first ssh into the appropriate network, then ssh into the individual machine. This works great and I can run programs no problem. The issue is that these programs can run for days or weeks, and the network kicks me out after some period of time due to inactivity.
Is there a way to start a program on a remote machine then terminate the connection but have it keep running?
This morning I ran the automatic upgrade provided on the repositories, updating my kernel from 2.6.38-8 to 2.6.38-10.Unfortunately, upon reboot I discovered that a series of patches I'd applied in order to get my wireless card on my desktop working had been undone (see I had to run a modified version of the instruction set in order to get my wireless back on.My question: is there a way to trigger this every time the kernel upgrades? I'd hate to have to run this cumbersome set of commands manually every time.

I have recently ported from Windows to Linux (xubuntu) I am a developer, i installed everything i need, LAMP. Now in Windows i used to turn off all unnecessary Services, i don't need the Apache or MySQL service running all the time. I used: net start mysql
Whenever i needed it. How do i do the same in Linux:
1. Disabling not-needed daemons from auto-starting?
2. Starting them only when i need them?
I want to create 2 cron jobs daily
1st cron: Every day by 13(1pm) I want to stop the httpd service
2nd cron: Every day by 13:30(1.30pm) I want to start the httpd service
I tried but only 1 cron job can able to run at a time.
Linux bash inline command to execute a program and limit the resource.As I know, to limit the resource I can use ulimit command.But, the problem is when I set the CPU time limit 1 second, and then I want to execute another program with CPU limit 2s, the ulimit command return an error like this: bash: ulimit: CPU time: cannot modify limit: Operation not permitted and absolutely my program killed in 1 second.So, How can I make the second program running with the CPU time limit 2 seconds?
View 3 Replies View RelatedI am using RHEL6 on a server with 3 interfaces.
eth0 is connecting via a Cisco switch to the outer world and eth1 and eth2 to internal networks.
eth1 and eth2 are working without problems all the time, however I have the following incident with eth0: although it is RUNNING, and after it works for some time (like some hours), it then becomes incapable of sending/receiving traffic. Here are more details, after the interface exits the RUNNING state:
[root@mgt ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr E4:1F:13:6C:87:74
inet addr:9.162.91.26 Bcast:9.162.91.255 Mask:255.255.255.0
inet6 addr: fe80::e61f:13ff:fe6c:8774/64 Scope:Link
UP BROADCAST MULTICAST MTU:1500 Metric:1
[Code]....
I am wondering whether there this is because there is not traffic for some time and so the interface goes to idle. Is there any parameter I can tweak in RHEL6 to force the interface to remain RUNNING even in the absence of traffic (although I would be expecting that some 802.1 packets would be periodically flowing from the switch to the interface)?
I have a script that executed 100000 C Programs, reads the commands from a file and executes them. There is a requirement to measuer the time that each of this 100K C programs running.If it exceeds 120 sec I want to Kill that Process.Any Idea to embed this in my shell script?
View 4 Replies View RelatedOn my server I provide OCR file conversion service but the problem is when a user uploads a file and it's being converted then if you open another tab and try to load the site it won't respond until that conversion is completed. In other words until the PHP script finishes execution apace doesn't serve any other request to the same browser.
Here is my apache configuration:

You can check what I mean if you try to upload and convert a file and while the file is converting try opening the site in another tab.

View 3 Replies View RelatedI have an Acer Aspire netbook with 1GB RAM and 1.6 GHz dual-core 32-bit x86 chips. The KPackageKit / yum / rpm chain is running too slow for me. In addition to the time required to download any new packages or updates, it seems to require at least one full minute of processing time to install each package, update, or bug fix, no matter how small. Another full minute is consumed for each package in "cleaning up."Running yum from the command line takes nearly the same amount of time.During this time, I cannot run any other applications without severe thrashing. It seems that a full gigabyte of memory is in use with some 100M swapped out to disk.
Is there any way to reduce the running time and memory requirement of the update process?While not updating or installing software, I do not normally run out of memory (i.e. begin thrashing) until I have about a dozen browser tabs open, or the like.

Currently on item "Configuring linux-image-2.6.31-20-generic" and the progress bar/terminal readout has not changed for an hour or so I'd say.
Don't want to cause issues by killing it halfway through, especially as it presents an opportunity to learn something!
I am currently struggling with one of my tasks.I was asked to find a way how to determine how much time an _already running_ process is spending in user and kernel space.E.G. <some tool> <pid>[Control] + [c]<pid> spent 12.1 seconds in user and 1.52 seconds in kernel space.Does something like this exist? Basically I guess I am looking for something similar to time, except that the process is already running.So..a) Is there a tool which fulfills this task?b) Is there a way to write your own software which does the job? Is it even possible to code something I am looking for?I recently found strace -c -p <pid>, but well, this is not exactly what I was looking for.
View 3 Replies View RelatedI would like "Back in time" to run as root when Ubuntu boots. The reason I want to run it this way is after I read the documentation it would seem that although you can take snapshots of folders which are root you can't restore them. That being said, it goes on to say that if run as root it would be able to.
First question: Is this safe for a home computer with one user?
Second Question: How do I make it run as root at startup?
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.
View 9 Replies View RelatedI 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.

For like windows you can resore your os to a state of peace kind of. If you messed up your vital files you could go back in time and restore you computer to a selected time. I was wondering if you could do that for ubuntu
