Re: When I need help no idea if is ubuntu lubuntu...
Ubuntu is the main distro, Lubuntu, Xubuntu, Kubuntu (well it's not anymore for Kubuntu) are all recognized distrobutions via Canonical. They all base their packages and code off of Ubuntu's base which is Ubuntu is a derivative of Debian - but since has branched off.
If you're using Lubuntu you're using what's called LXDE - Lightweight X11 Desktop Environment.
If you're using Ubuntu you're using what's called Unity - it's a dashboard based Desktop Environment that left behind the old Gnome2 packages - instead of going with Gnome 3 they made their own variant for a more polished version of Linux.
If you want a starter guide you can try this site it looks like it has good information on what's what - more geared for Ubuntu: http://ubuntuguide.org/wiki/Ubuntu_Quantal
If you're a real beginner and don't want much hassle of trying to figure out how to install this or that, you can use Linux Mint. Don't use Debian Edition as that's what they call a "rolling release" which means that as soon as packages are updated, they are pushed to your system. Instead of verifying that they're stable and work with other core-components to make sure they don't crash, they push it out - the latest and greatest - so you're system can break easily with it (granted I haven't had an issue yet).
Linux Mint was based off of Ubuntu but they now use more Debian than Ubuntu - it's a whole structured Tier of things - as an oversimplification:
Debian makes packages and puts them into DEB files using (depending on Testing, Unstable, or Stable) whichever version you're using. It's the barebones so to speak so it gives you the basics to get up and running. They don't have a software center like Ubuntu does, but they use Synaptics (which can be hard to figure out at first).
Ubuntu uses Debian as it's base, but configures it more custom-like for what it feels users should have, it then runs its own repositories (software caches) for users to download based on what they feel to make the system the best in their eyes. Usually newer software (not patches or security updates) aren't pushed out until a new release (e.g. 12.10, 13.04, 13.10) and they have a specific release schedule - every 6 months. PPAs are setup to where other users/developers/etc. can compile newer software and make it available to others to install - maintaining certain libraries and packages as well that may be required to install said software.
Now Kubuntu, Lubuntu, and Xubuntu take it further by taking Ubuntu and using their own set of packages, stripping what they feel isn't necessary and running their own DE (desktop environment) K = KDE, L = LXDE, and X = XFCE
You can always as questions and we'll answer. This is a very basic and oversimplification of things but it may help.
Where's [slooksterpsv] been? - I had Catastrophic partition alignment failure. I lost 90%+ of my data, and just now got it back fixed and working.
