Okay, now try to describe in some detail what you experience. I get that you only have 800x600 screen resolution. Searching for your model gives mainly hits on replacement batteries, so I assume it's not too new.. probably has 1024x768 as native resolution?
When troubleshooting via a forum like this, using the command line usually produces the best and most accurate results. Let's experiment a little. Highlight and copy the following line:
Now open a terminal (shell, command prompt) window. Hit the key combination Shift + Insert. You should see the above text being pasted into the terminal. Now hit enter. You should see text scrolling by in the terminal window. If that works, take it one step further; copy and paste this line:
cat /etc/X11/xorg.conf > $HOME/Desktop/xorg-file.txt
After this you should see a new file on your desktop "xorg-file.txt". Open it in a text editor, copy and paste the output into your next post. Hint: to make it pretty, highlight the pasted text and click the # button in the message toolbar, that will create a nice scrolling box which keeps your post more readable.
