If I start it up, and it's fast, it's like that through out. But if I start it up, and it's slow, it is slow like that for a whole time, and doesn't recover. When that happens, I saw the CPU almost 100% all the time. The hard drive light indicator would be on all time time. The top command doesn't indicate any process that use a lot of CPU. It just has a high "wa" percent. My remedy so far is to restart the machine, and hopes it's fast again. Sometimes it does sometimes, it doesn't. It always start up to the login screen very fast.
However, even before logging in, I can see it's slow if the hard drive light is on all the time, and not blinking). Even typing in the password would show a slow echo of the *. This is OpenSuse 11.2, 64 bit. The file system is ext4 (I wonder if it has something to do with this). Does anyone have any pointers on how to troubleshoot this? I may do a re-install. However, if the hard drive is failing, then I'll just back up and wait for the day it stops working.
I am currently using opensuse to run a server, however I am experiencing some difficulties. Every once in a while, and I mean completely randomly. This will occur out of no where, and then not happen for five days, then occur twenty times in a row. What happens is the computer runs fine, and all is well but suddenly it wont connect to the internet. All applications are fine and everything is working. It isn't frozen, just won't load webpages. I am using a belkin 111v2 wireless g adapter and it usually works fine.
So when the internet freezes, if I unplug any usb the computer freezes. The mouse stops moving and the keyboard won't respond. The caps lock light won't even turn on. However the laser on the mouse is on, but the computer won't respond. Its like its shutting off the usb hubs. The only thing to do is force shut it off and restart until i no longer have the problem. Sometimes it helps if I open it and re-seat the ram, but that gets old. Does anyone have a solution?
I have faced following problem in my office opensuse server there are 6 users working at a time from terminal.all are using java,php eclips programming application.The system is working fine for every user as reported.but it is going to be slow if we start any macromedia flash 8 releted web application on browser.I have checked memory,cpu usege also check iostat,mpstat everything on it ,no such difference.
I'm stuck in the "log off" mode. I don't get the shut down menu. It started when I turned the computer on today. I got a verbose boot up and had to login and enter password and run "startx". Then I got a gray screen before the splash screen.
I had been trying to get alsa to start in the "runlevel" section yesterday, could I have messed something up in there causing this?
I was wondering if it is possible that some gnome themes can slow down the computer. Do they have any impact on performance? Will it use more resources, such as CPU and RAM?
I have 2 computers connected to my linksys router via ethernet cables.
My main computer is running Ubuntu while the other is Xubuntu.
When both comps are on, the internet works fine, but when my second computer is off, my main computer has super slow internet. Sometimes it takes 2 minutes and I get "This webpage is not available", and then I refresh that and it finally loads.
Why does it work when both comps are on? What could cause this?
What must be the best configuration of computer for linux? I have 2.67ghz, 1gbram, 160hdd and running linux-ultimate-edition but computer is run very slow.
1) I have installed centos 5.2 on my desktop computer, it was very slow i couldn't even copy from pendrive to harddisk, if i do mouse pointer stuck and move no smoothness in working in centos...! can't work ! (i have installed minimal installation and also turned off many service using chkconfig command) specification of my computer :---- gigabyte 8 series mobo and pentium IV 2.6 GHZ, 1.2GB Ram, and 6200 GeForce nVidia graphic card ----
2) After installation ntfs-3g it won't work to access harddisk.
I installed OpenSUSE 11.2 on a computer. I would like to clone the hard drive so that I can put the same disk image on another computer with the same hardware.
I used clonezilla to create the hadr disk image, when I restore the image on another computer, I got errors and failed to boot. I later learned that, I have disk-by-id on /etc/fstab and grub/menu.list. So, I went into the computer that I tried to restored using Knoppix liveCD and manually changed the fstab and menu.list so that it used something like /dev/sda1, /dev/sdd2, and /dev/sda3, instead of /dev/disk/by-id/WD....-part1 (part2/part3). When I re-booted the new computer, it still failed to boot.
So, do I have to go back to the original computer, manually edit fstab and menu.list to /dev/sda1 /dev/sda2 /dev/sda3, then re-create the disk image? Is there anything I have to change so that it does not use disk-by-id any more?
Is it possible to have a tri-boot system ? I currently have a dual bootsystem on mydesktop. Win XP & Ubuntu. I want to add SUSE 11.2 but don't know how to go about loading it onto my machine. On restart the computer does not recognize the CD in my rom drive and only asks if I won't to load Windows or Ubuntu. How do I go about adding another OS to my hard drive ? I have an old Gateway with 130Gb hard drive and plenty of unallocated drive space and 512Mb of Ram. I use Windows rarely (almost never but do need it for some applications) and mostly rely on Ubuntu which my wife and I both like and use daily but I want to look at and experience other Linux installations as well
I added a second internal hard drive (/dev/sdb1) to a SuSE Linux system. I chose /home/users/STORAGE as a mount point. If I navigate to /home/users/ and right-click on the STORAGE directory and choose properties, I can see the amount of free space in the sdb1 partition of the second hard drive. Everything looks as I expected it to.However, if I choose the 'My Computer' option, click on home from there, which is where /dev/sda1 is mounted) and then navigate to STORAGE, the address bar in Konquerer looks something like this: da1:/users/STORAGEI might not have the format completely right but I do know that sda1 is listed at the beginning of the address. Yet if I copy files into this directory they end up in sdb1. Are there any issues with accessing the directory this way? When I right-click on STORAGE after navigating to /users/ through the My Computer page, the space used/available does not reflect the sdb1 partition.
A second question I have: On the My Computer page each mount location is shown in the top-right corner. The name of the new internal hard drive I added is displayed as "1TB media." That name is also a link to the mount point. How can I change this to something else? I would avoid using the My Computer page all together but there are many other people using this system and most of them know no other way to access thedirectorie
i have missing icons for the computer icon and mozilla icon and the start menu and and task bar are gone as well. i tried running the kicker and plasma command but will not execute type the command after pressing alt + f2. im running kde 4.3.
has been a very slow rate of transfer from the computer to the USB on openSUSE, and the pendrive to the computer is much faster, I've tested other distros and the performance was very good. this is from the version now in openSUSE 11.2 and 11.3.
FTP from and from my home computers to 2 remote servers has become really slow over the past month. One of the remote servers I manage and the other one is taken care of by a hosting company, so I am thinking the problem is residing on my end. It doesn't matter if I am downloading 1 file or 10 files, they are all coming in at 9 kb/s which is really slow cause I have a 7 megabit connection. I've tried using multiple computers and still have the same problem. I am using proftp for the ftp server and filezilla for the client.
My friends computer is extremely slow with all versions of kubuntu. Its very slow to boot, very slow to load applicatons, very slow to switch between windows, very slow to do anything. I can't think of what would be causing the slowness, its not new, doesn't have any fancy hardware AFAIK, but it runs XP perfectly well, its probably a 2.0+ghz pentium 4 processor. Do you think it could be a kernel chipset issue? Or perhaps a graphics driver/window manager issue? I don't know what the hardware is, is there a command I can run to list all the hardware?
I am running into a problem with my cpu using a lot of usage with no applications running other than firefox, one window... then the screen would dim as if it is going to screen saver mode, which is not set to do that after 473 minutes of being idle...because I watch full length movies... so if anybody knows about this please let me know, i dont know if I have a virus, but maybe xscreensaver is conflicting with Gnome screensaver builds or something.
I want to do a stop-motion but I cannot find a program that has all the option I want and that is useable for me. I tried with Kdenlive that has all the option I want, but when I want to see the preview of my video, it lagged at every new image.Is there a format, a way to configure kdenlive or something else that would make it easier for my computer. Or even another program that do what I want but is less demanding then Kdenlive.All I want is to put picture one after the other, adjust the time they appear and add some text and sound.
My notebook is using intel core 2 duo T6400 CPU and 2GB Ram, when I am playing MP3 with Amarok and at the same time running Firefox, the computer tends to hang and slow in response to open new website.IS it due to my hardware?
After I burn the DVD image, I put the disc on the computer and boot. The installation screen appears, the acknowledgement screen appears, then the installation checks my system and gives me a yast window with an error about something related to URLs and repositories. I cannot continue with the installation.
I am 100% new at this and thought it would be as easy as installing ubuntu (which I installed on a laptop and works flawlessly).I am trying distros and opensuse is compatible with my video card right out of the box apparently, so that's why I chose it for my desktop.Do I need to copy the dvd image to the hard disk of the computer I want to install opensuse on, and use the dvd to boot as well?
My macbook pro stopped booting yesterday due to some file system corruption in the hard drive. I am able to access this drive through a linux live cd which I am using now but when I go to some folders it says "Could not enter folder /media/Macintosh HD/..." My question is how do I give myself the permissions to be able to access these files and transfer them to a network drive?
I recently install Ubuntu-studio Desktop and some other packages. And, I upgraded my System. But since then, the Grub has started to display (I have only 9.10 installed, using the entire Disk). Also, unless I select the entry, Grub does not automatically start. The startup takes nearly 1.5 minutes. And, the Login screen, after the installation of Ubuntu Studio GDM, is much slower. I removed the Ubuntu-studio GDM package, still it takes about 20 seconds to allow me to enter Username and password. Any idea?
I am having a problem with my Fedora11, I am not sure wether it is software or hardware but this looks serious. My computer is running very slow and freezes up every few seconds. Every time I reboot I would get a kernel failure pop-up.
Where are temporary internet files stored so as that I can delete them. A second point is that I have had Ubuntu for a few months now and my computer is starting to slow down.
I first noticed the problem because my wireless internet will stop working. The usb stick has its LED constantly on but it fails to connect. I have tried some methods of restarting the networking, like "sudo restart network-manager", disabling and re-enabling the wireless and networking from the taskbar applet. I tried removing the module and restarting it. It might be a bigger problem because I'll find that things will randomly hand for awhile, like opening system monitor, or running terminal commands. They do eventually run but only after several minutes. A restart seems to get everything working again, but the problem comes back at random times. I am willing to solve this right now as I have time, just let me know what info you need and I will post it.
Update: Some more info I forgot to include. I am running Ubuntu 11.04. It just froze again, I tried logging in and out but the internet still wouldn't work and things were hanging, I couldn't get file manager open. I have even tried shutting down the computer and had it stall on the Ubuntu logo with the dots loading so I had to hard restart.....
I had put a second Sata hard drive in my computer and was pleasantly surprised not to run into any problems. No BIOS changes, just start the partitioner, partition, mount, it worked.And then... my computer didn't boot today.I disconnected the new hard drive and it went a little bit further, allowing me to log in as root and remove some lines in /etc/fstab. After that, it booted without any issues.I then remembered that the new drive was /dev/sda and the old drive /dev/sdb. I assume this is the reason for not booting, there is no GRUB on /dev/sda. How do I fix this? Can I simply plug in the cable for the new drive where the cable for the old drive was?
I have a 2TB USB drive which I use as a backup device - I dump two filesystems onto it, totalling around 1TB. However, doing the dump trashes my F11 system, making it basically unusable, not only during the dump but also afterwards. I have 8GB of RAM, all of which is needed and normally in use, but when dumping, the system starts hogging huge amounts of it as buffer space - up to 1GB of RAM is reported to be allocated. And rather than using free memory for buffer space, it seems to aggressively swap processes out to get it. The system tends to melt down as a result, and just switching virtual desktops can take 5 minutes.
But after the dumps finish, the problems continue - the system is currently trying to keep around 700-800MB free, and continually swapping out processes to do so, even after the buffer space in use has gone back to about 100MB. This seems like strange behaviour for a fairly common type of activity. Presumably a lot of the buffer space is used to store what is being read from the filesystem (which will never be needed again), and some is used to cache the writes to the USB drive which is slower than the internal hard drives.
I have spent a lot of time trying changes to some of the kernel parameters, after reading articles about them. Of all the ones I've tried, setting vm.dirty_ratio to 1 instead of 5 helps a bit, and setting vm.dirty_background_ratio to 5 instead of 20 makes some improvement I think. Setting vm.swappiness to 0 doesn't seem to help at all.
So my question (at last!) is - how can I back up my filesystems without my system dying? In particular, can I limit the space used for buffers somehow, or turn off buffering for the dump process? And why does dumping result in the system artificially keeping huge amounts of space free afterwards, so I have to reboot to make the system usuable again?
