I have a Sony laptop and never experienced this until this past week. I use both a USB mouse and USB keyboard and have found that the disappearing mouse problem only surfaces when I plug the mouse into the USB bus available on keyboard. If I plug both the mouse and keyboard directly into laptop the problem doesn't occur. I suspect some piece of software has been changed recently but haven't had the time to try and track it down. Logitech Keyboard: Y-BC9 Logitech Wheel Mouse: M-BE58 Regards, Mike Klinke
It's the kernel which has been changed. If I boot up one of the earlier released 2.6.9 kernels the mouse behaves as before.
Cheers,
