I'm new to Unix/Linux and someone suggested I try Ubuntu. I like it but I can't figure a couple of things out and don't really have time to google up ways to solve the problem. Answers from a quick search were so confusing. Can someone provide me with a straightforward set of instructions with easy places to click and download packages for the following problems:
1) I manually placed an icon on the Ubuntu desktop. I want to remove it but can't figure out how! When I delete it, it's completely unaccessible on the original left side tool bar.
2) Where/How do I install Java for Ubuntu 12.04?
3) Where/How to I install a de-coder that will let me play a regular movie DVD?
4) How do I go back to installation options and allocate more computer space for Ubuntu and less for Windows?
