Emachine9643: Not there...... Still new to this and have no idea how to properly navigate the OS. But I did goto the menu and searched and nothing.
Don't know if Compiz is automatically installed in every Mint, I'm using the version with the MATE desktop and got an Nvidia card by now, but will probably switch to XFCE soon. If you want to install it, just type "compiz" into the search bar in Synaptic.
In case you haven't used Synpatic yet, it's the perfect tool for lazy people like me who want to avoid using the terminal. It's the sixth entry above the menu-button and can install all kinds of applications for you, there are even a lot of OpenSource games in the repository including the awesome "wesnoth" and "openttd" which are must-haves.
Emachine9643: edit- What packages should I download? everything for level 1 to 3?
I guess you mean the updates and yep.
If all your problems are solved and your system is running great, you only need the security updates (marked with a "!" ) later.
