Hello,

I too am a new user to Ubuntu. I have an old Gateway M500B1 that I want to use for my 9 year old to surf the net and play some online games. I decided that moving into the Linux world would be better than sticking with Windowz on this machine.

I installed Ubuntu 12.04 yesterday. The install went fairly well until boot up. I have two issues I am currently working on:
1. the display only fills about 2/3rds of the left side of the screen and appears to span from the top of the page up again from the bottom. In other words I see the top screen bar/icons on the bottom of the screen and if I point the cursor at items along the top I see the cursor moving along the bottom. Hope this is making sense.
2. the same wireless issue as the OP.

I tried what was described in this thread and here are my results after following the last post:
