Dual-booting mandriva and running slow

[gla3dr]

I just installed Mandriva Linux Spring 2010 64 bit on my laptop and it is running slow. When dragging windows around, there is a trail left behind of the window being dragged. Also, when closing windows or scrolling, the change on the screen appears to refresh from the top of the screen and moving downward, instead of the window instantly disappearing or scrolling smoothly.

I am dual booting it w/ Windows 7. To install, I booted the laptop from the disk that I had made of the Mandriva ISO, then went through all the steps of the installer. For partitioning, I chose shrinking the windows partition and made a new linux partition, which is 32 GB.

My laptop specs are as follows:
Intel Core i7-720QM
ATI Mobility Radeon HD 5870 - 1GB GDDR5
2x 500GB 7200RPM HDDs
8GB DDR3 RAM

I would think that this laptop should be able to handle Mandriva with no troubles at all, so have I done something wrong while installing Mandriva, or are there some settings that should be adjusted? Any help is greatly appreciated.

Thanks,

Hi and Welcome !

Have you installed ATI Proprietary Driver?

[gla3dr]

No I haven't. How would I do that? I'm new to Linux and still learning.

EDIT: I figured out this ATI proprietary driver thing. It seems to have solved the problem. Thanks!
