I recently bought a new laptop and installed Ubuntu on it. Unfortunately it seems the touchpad is not supported - I can live with that.

Problem 2 is that the mouse is not working properly. On boot it works fine for a while, but then functionality deteriorates - only some areas of the screen is clickable, windows don't get focus when clicked, wheel-click don't work etc. The pointer is still moveable and some areas can still be clicked - ie. I can select text in the terminal.

I have no idea where to start looking for a solution for this issue. Any suggestion to a solution or where helpful debug information can be found will be much appreciated.

The USB mouse is a Logitech G500 which I'm using without issues on my Desktop computer with Ubuntu 13.10.
