THis is my first time using linux. I am running it on a amd 2600+ system with 1.5gb or memory and a 9800xt. i am in a dos style screen where it asks me to log in. i do so and it comes up with "striker@striker2:~$ " i am unsure what to do now. i am purly using this pc for the web and messaging since i just built a new amd x2 PC.
