ati - Is Ubuntu using my Graphics card?

So i have a AMD CPU with Radeon HD 3200 as integrated graphics, and i recently found a All-In-Wonder AMD Graphics card (pretty old) and used it but im not sure if ubuntu is using it, or if it's still using the Radeon HD 3200. When i look at the info about this computer within ubuntu it says my grahpics is: Gallium 0.4 on AMD RV635. Help?
