    Complete newbie with Ubuntu - first day. My Ubuntu is slow...need to diagnose

    just installed the latest 14.04 LTS -32 bit version. I feel there is some lag....it's not that fast. I am sure it needs tweaking, but i dont know how to diagnose the problems or fix them. Anyone can systematically show me what to do?

    I have an old computer

    Gateway MX 6437
    2 GB of RAM

    what graphics card do you have? Ubuntu is modern operating system aimed at latest mashcines. for older and slower computers using Xubuntu or Lubuntu works best. Ofcourse Ubuntu can also be used but needs to be tweaked quite a bit. and 3D accelerated unity interface might need to be dumped.

    Welcome to the Ubuntu Forums

    I suggest that you try some other flavour of Ubuntu with a lighter desktop environment, Xubuntu which is medium light or Lubuntu which is ultra light.

    If you have a fast internet connection, I suggest that you download the corresponding iso files. You can use 32-bit as well as 64-bit versions, and I think with only 2 GB RAM, it might be better with 32 bits (others might advice differently).

    -o-

    If you have a slow internet connection, or you want a quick solution, you can install the corresponding flavours or only the desktop environments with the following commands from a terminal window

    Code:
    sudo apt-get install xubuntu-desktop
    sudo apt-get install Lubuntu-desktop
    Code:
    sudo apt-get install xfce4
    sudo apt-get install lxde
    and then you can select the desktop environment at the login screen. But this method means that the system will get doublets for many tasks, and it is difficult to get a clean system (again).

    Re: Complete newbie with Ubuntu - first day. My Ubuntu is slow...need to diagnose

    newbie questions:
    - should i have downloaded the 64 bit? would it have made any difference?
    -Based on the specs, should i downgrade to a faster distro, Xubuntu, etc..if so, which one is preferrable (i use this laptop only for web browsing - no gaming)
    - is it possible to keep Ubuntu on and run other lighter version of Linux. if so, whats the quickest way

    Sorry, lot's of questions. Recent convert from Windows, quite literally one day, but already loving Ubuntu.

    I think it makes no big difference in speed. A different desktop environment and a different choice of application programs will make a bigger difference.

    I think Xubuntu might be a good choice. You can test both desktops in the same system according to the second alternative in my previous post.

    Thanks for your prompt replies, guys. Appreciate it. I am going to try to use Xubuntu. Just curious, the tweaks to make Ubuntu faster, is it a tremendous effort? I am just trying to assess the level of difficulty.

    Standard Ubuntu is not very easy to tweak, instead it is made robust and for relatively new computers. The community flavours (Xubuntu etc) are easier to tweak.

    They install the other desktop GUI software.
    apt-get is the software package manager for installing and removing software.
    sudo is a command that effectively means "run the following command as administrator".

    So "sudo apt-get install xfce" says that as administrator, install the package xfce4. xfce4 is the GUI that Xubuntu uses. Similarly, lxde is the GUI that Lubuntu uses. You can install them all into Ubuntu, and have a choice of which GUI to run as you log in.

    However, I would suggest that you go ahead with a complete install of Xubuntu and overwrite Ubuntu. Ubuntu will load a number of services that are of little use in the xfce4 GUI, and Xubuntu loads a number of services that are of use in xfce4 and not loaded by Ubuntu. Your best experience will be with the *buntu version for the GUI you intend to use.

    Good luck with it.
    I don't think you will find any easy tweaks to make it faster. They try to make it pretty-much as fast as they can before they release it. You won't find a settings slider that says "Glacial" and one end and "Ludicrous Speed" at the other end.
