[Problem]
External screen with VGA shows corruption when enabled, and if mirroring set
both screens show corruption.

[Original Description]
I am attempting to set up dual monitors for the first time in ubuntu. I
recently upgraded to 10.04. on both monitors I have the image I get is corrupt
on the monitor, and if I set it to mirror the displays my laptop screen becomes
unresponsive and everything on it is whiter. I am trying to set this up through
vga. I can still move the mouse around on the corrupt screen and see it fine.
