Double Pointer Upon Screen Rotation

[Adam Smith]

On a Fujitsu Lifebook T5010 (http://goo.gl/j2Eag2 T9550 type), when the screen is rotated a full cycle (pressing the builtin shortcut button 4 times), the pointer is show as two pointers: a normal, "active" one on the left and a "lame", 90 degrees, clockwise-rotated one on the right. Both pointers move in tandem, but only the left one is effective. Screen captures do not record the right pointer, so example without mock up is impossible. Logging out and logging back in does not seem to resolve the issue, nor does restarting the laptop. Other users are not affected, but the issue can be replicated by other users.

In addition, when an affected user logs out and logs back in, the screen is rotated 90 degrees clockwise, requiring a single push of the laptop's rotation button to set it back to 0 degrees (no rotation).

Although I have been able to correct this manually, I cannot determine which of the steps I took were effective.
