I'm a new user here and I'm also a Linux newbie. So last night I tried Ubuntu for the first time (kinda), and as I was getting the hang of it I noticed an option to update my OS to version 12.04, so I said "Why not? Let's start with something fresh and new"... Bad choice. As soon as the process was over and I restarted my netbook (I first had some problems booting it up), the desktop appeared and I was like, what?
Some parts of the taskbar were black, the resolution was way too low (even for a NETBOOK) and I couldn't even find the start-like button to show all of the apps. Pretty good for a first time, huh?
I apologize if I don't add much information or a picture, I don't even know what version I had before I updated! I guess it's a matter of time until I learn the basics of this OS.
If someone could help me to revert this (maybe getting back to the previous version) I would truly appreciate it. Thanks in advance.
