This may actually be in the WM, or cause by it. When I was looking for a new
WM for users, I did note this behavior on some and not others. Since I was
running on the same kernel and video driver, it seems to me that either the
WM is actually doing this in areas where it doesn't show the pointer, or
that it is loading an X driver with is causing this. Since I did see this
first in a VM, then on a live fc16 install, using totally different video
hardware, it's unlikely to be just poorly supported hardware.
The OP might try using VNC for access, to see if that provides any useful
info. I do believe the WM is making the cursor vanish when not moving.
I thought the WM too, but it's different between different kernel
versions, which suggests Alan is spot on. However I've also got a
kernel bug ongoing at the minute, so probably sensible to wait until
that's resolved (the kernels with the problem are being booted
acpi=off, which seems unrelated, but you never know).
