right package for what might be a mother board problem

[eric]

operating system ubuntu 9.04 amd64
video card radeon 9000 pci
mother board intel dp43tf

bug:
The mouse icon is a white rectangle 1 inch long .5 inch tall.
There are small speckles above below and in the rectangle.
I have attempted to change the mouse pointer icon using the gnome tool
in appearances to no effect.
The mouse works but it is difficult to use as the pointer does not make
it clear where the activation spot is.


I just installed this mother board to replace an abit intel ip35v.
the old board did not have this problem.
I have debian 5 on this hard drive and it has the same problem ...the
kernel is older.
