I have a Gateway notebook with graphics card

01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series] with open source driver

Linux version 2.6.32 -28 - generic. No other operating system on the computer.

When I am using firefox to browse the web, everything normally works just fine except that when I attempt to access some particular web pages the screen completely messes up going mostly white with various streaks, etc., although I can access other pages of the same site without problems.

When I run the cursor over the garbled screen, bits of the image recompose themselves, at least partially, and I can continue to open the applications window, or turn the computer off, or open the terminal, or take screen shots, etc., although all menus are unreadable.

Also, when I zoom in on Google Earth the screen completely messes up. At all other times, there are no apparent problems.

Any ideas?
