Graphic card drivers

[WeldonJ92]

I am a new user of Ubuntu and have very little understanding of how it works.

I have installed Ubuntu 12.10.
I am running Ubuntu 12.10 on a HP Pavilion G6.
The graphic card this laptop uses is a AMD Radeon HD 6480G.
Ubuntu is not using the graphic card driver that it should be.
Instead I think it is using 'vesa', which I think is a very low 2D-specific graphic driver.

I have already searched for how to install this.

I know how to open the 'terminal' and I know that sudo is something about installing and that sometimes I am prompted for a password.

If someone knows how to install these drivers, that would be brilliant.
I would like to use Ubuntu, however if these drivers won't install, then I can't. :/

Thanks a lot!

Edit:
A website said that my graphic driver was something else, which I did eventually install I think, but then Ubuntu would not boot and would hang at a black screen with a blinking white cursor. I then booted Ubuntu in graphic safe mode, but this did not work either.
I then found information suggesting that my graphic driver is something other than what a website had said.
Since then I have uninstalled Ubuntu and installed a fresh copy of Ubuntu.
I have not changed anything within this copy of Ubuntu and am waiting for someone more knowledgeable than myself to explain.

You don't need to use the terminal at all. Just go to System Settings > Software Sources > Additional Drivers and choose the driver for your graphics card.

I will try that in a few minutes.
I hope it works.
Thank you.

Hey.

There are 3 additional drivers.
- Using X.org X server - AMD/ATI display driver wrapper from xserver-xorg-video-ati (open source, tested)
- Using video driver for the AMD graphics accelerators from fglrx (proprietary)
- Using video driver for the AMD graphics accelerators from fglrx-updates (proprietary)

Which one should I use?

Thanks a lot.

Try the second one (fglrx).

Try the second one (fglrx).

Okay, in the details window it says:

Driver: Unknown
Experience: Standard

Should I restart the computer?

Thanks.

The graphics have changed to VESA now.. :/

The graphics were actually working better until I did that.
Now they are lagging.. o.o
Haha..
