Hi guys,

I have just installed Ubuntu 10.04. My CPU usage is high when I do trivial things such as scrolling through a PDF file. So I think my video driver is not properly installed.

I want to confirm that by checking the information of my currently installed video driver, such as if there's a driver installed and what version it is. Then I could decide whether to install a new one if it is not up to date.

On Windows, I could use the device manager, how to do that on Ubuntu Linux? I don't expect a GUI solution for this. Command line will be just good enough.

Many thanks.
