I performed a custom install. During the install, I selected the entry
for the PS/2 Microsoft Intellimouse.
When I initially tried to start X-windows, my mouse cursor zipped off to
the upper right hand corner of the screen. No matter how vigorously I
moved the mouse it would very rapidly return to the upper right hand
corner of the screen.
I had to manually change the Protocol value in the Pointer section of
the /etc/X11/XF86Config file from "PS/2" to "IMPS/2" to get X windows to
work. The install should have handled this configuration issue.
This is related to Knowledge Base request 209, but I think that this is a
legitimate install issue. It took me several hours to figure this out.
This issue is resolved in the latest installer from RawHide.
