    Painfully slow OS

    Hi,

    Newbie here, and apologies if this is in the wrong place. After a year of constantly having to reinstall Windows 8, it finally died (including the partition restore files) and I installed Ubuntu. Now it seems really good but it's painfully slow, with the windows "greying out" which makes it virtually unusable. The odd thing is, is if I run it from the USB it's super quick.

    Any help would be gratefully appreciated as the USB version of the OS is really impressive.

    Many thanks.

    Re: Painfully slow OS

    Please give specifications of the computer and the ubuntu version you installed.

    Greyed out apps mean the system is busy and they wait for it to continue working. Could be several things. How much memory do you have, how much swap ?

    Shots in the dark :
    Code:
    sudo fdisk -l
    free
    df -h

    OK thanks, does not look like you are on low specs
    Could you please post the output to the other commands ? I may not be able to help you but others will, thanks.

    Edit : please do not try to draw tables, just paste the text in here, and wrap [code][/code] around it : http://ubuntuforums.org/misc.php?do=bbcode

    Re: Painfully slow OS

    since you say that windows 8 just 'died' along with the partition table, and that ubuntu is exceptionally slow, would make me think that your hard drive may well be failing

    the fact that the whole computer works fast with a USB flash drive furthers my belieif that your hard drive is the problem.

    i would suggest you either call up whatever brand name your computer is and ask them for a new hard drive replacement - if your computer is under warranty and if you don't mind them giving you a basic hard drive - or buy a new hard drive yourself, or even a solid state drive if you really like the speed of the USB stick. then replace the hard drive yourself - it's not difficult, you should be OK with a little reading

    simple benchmarks for hard drives can be found here: http://harddrivebenchmark.net/hdd_list.php

    Hello!

    Please install smartmontools

    Code:
    sudo apt-get install smartmontools
    If this is a SATA drive (assuming sda is the device your OS is installed on), run

    Code:
    sudo smartctl -a -d ata /dev/sda
    Highlight all of the resulting text in the terminal and press CTRL+SHIFT+C to copy it.

    Paste the text back here between code tags:

    If you are using New Reply button - highlight text and use the # button in the text box header.

    If using Quick Reply then [code] at the beginning and [/code] at the end.

    That should give us a pretty good indication of the health of your disk.
