    Upgrading computer components, do I need a reinstall?

    I'm planning to upgrade my Ubuntu box with new hardware and only the old hard drive will survive. Processor will go amd 1800+ to 2400+, memory will increase from 700meg to 1gb and the video card will go from accent nvidia mxsomething to ati radeon 9800pro. Obviously also the motherboard will be changed.

    The question is, that do I need to make some preparations before chancing the parts or do the Ubuntu work fine after changing the parts? Of course I have to install new video card drivers, but other than that? Or should I backup my home-directories and reinstall everything? If yes, is there anything other to backup before?

    I would backup my /home directories and try it. It should work but if there are wrinkles (massive hardware changes you never know) you can fall back to reinstall and restore from backups.

    A re-install would be the best bet. If you want to save a list of all installed packages, use the terminal command
    Code:
    sudo dpkg --get-selections > packback.txt
    This will save a list of all packages in the file 'packback.txt' in your current directory (normally home).
    When you want to re-install all packages run the following
    Code:
    sudo dpkg --clear-selections
    dpkg --set-selections < packback.txt
    sudo aptitude install dselect-upgrade
    Hopefully the PC will then download and install all your old packages.

    I'd do a new install. Also perhaps look at an Nvidia card instead of ATI - I think they do generally work better with Linux although ATI have improved their support.

    Nope, ubuntu should work fine with these hardware changes. However, to be on the safe side, make a backup of your entire system using remastersys; it can also create a live CD from your system setup, which you can use to test the new system before you commit your hard drive to it!
