    Download Gsmartcontrol from the Ubuntu Software Centre. Open it and double click on your hard drive. Go to the Attributes tab and tell us the Raw value for Reallocated Sector Count, Spin-up Retry Count, Reallocation Event Count, and Current Pending Sector Count. Also, you can go to the Perform Tests tab and select Short Self-Test then click Execute. You may also want to run the Long Self-Test but that will probably take around 2 hours.
    My main hard drive :
    reallocated sector count : 1
    Spin-up Retry Count : 3
    Reallocation Event Count : didn't find that one
    Current Pending Sector Count : 0

    The secondary one :
    reallocated sector count : 0
    Spin-up Retry Count : 0
    Reallocation Event Count : 0
    Current Pending Sector Count : 0

    both tests completed without error

    It only says "no proprietary drivers are in use on this system" and nothing else ...

    Linux running slower than Windows isn't normal, as long as you compare apples to apples. In this case, we are comparing apples to oranges. Windows Vista is a six-year old system. Ubuntu Precise is a one-year old system. Mainstream support for Vista ended the same month Precise was released. The two have basically equivalent system requirements.

    An apples-to-apples comparison would be Windows Vista to Ubuntu Gutsy (Gutsy would scream past Vista, though it would be much less glamorous) or Windows 8 to Precise (Precise would be faster).

    Your hardware is definitely adequate to run Precise, but 2 GiB memory isn't all that generous, and neither is your Pentium dual-core.

    Running an unsupported OS is generally a bad idea. If the speed of Precise noticeably slower than Vista, but still definitely useable, my recommendation would be to stick with Precise. It will be supported until April 2017, by which time your machine will basically be obsolete.
    My windows seven on a bad laptop is also faster !
    Should I move to xubuntu or something like that ?

    so best suggestion is install 12.04 or 12.04.1 and then install additional drivers (proprietary) then it should work well.

    option no. 2 - add opensource drivers PPA (xorg edgers) that will install latest opensource drivers.

    another option (but this doesn't really solve the drivers issue) is to use a desktop that is not 3D accelerated (e.g. Xubutnu desktop or LUbuntu desktop)
    How do I know if I have 12.04/12.04 1 or 12.04 2?

    Re: Computer slow

    Well,I don't remember the CPU in the laptop anymore but it is pretty slow
    Ok so I have ubuntu 12.04 2
    How can I go to 12.04 1 to get the drivers ? What other differences are there with 12.04 2 ?

    You can download the .iso for 12.04.1 at http://old-releases.ubuntu.com/releases/precise/

    Re: Computer slow

    In my experience Ubuntu is always slower than W7. Unless you are an expert in optimizing and removing what is not needed in Ubuntu than W7 is a better choice than Ubuntu. But there is Xubuntu which is the best choice I'm speaking in terms of 'old' hardware (dual core with <= 2GB memory).

    You can try downloading from here and following instructions.

    Re: Computer slow

    So do I need to install it all all over again ? Isn't it possible to keep my applications and everything ?

    Re: Computer slow

    If you set up UbuntuOne, you can use it to back up your list of installed applications (through the software center).

    One reallocated sector can be a sign that your hard drive is failing, but it could also be fine if the problem is just isolated to that one sector. However, Spin-up Retry is bad news, I always replace a hard drive if it has any value other than 0 for that.

    Re: Computer slow

    Since the drive is not spinning up and down all the time I would exclude HDD as a source of your problem.

    Thanks for the info. As all my important files are saved on other drives as well, I'm gonna keep that one for the moment.

    For the slow problems. I understand two things, xubuntu might be a good alternative and I should install the proprietary drivers. So, isn't it possible to install the proprietary drivers in ubuntu 12.04 2 from this website http://support.amd.com/us/gpudownloa...eon_linux.aspx ?

    I saw that it is quite easy to install xubuntu next to ubuntu. But then I guess I will have xubuntu 12.04 2 and I won't be able to download the proprietary drivers either ?
