Hi I don't know what happen with the latest update, but now my mouse is frequently freezing and stop responding and I have to wait 5 - 10 secs for it to come back to life. I am using a wireless mouse, the mouse is not an issue because when I boot into SystemRescueCD and use the xfce windown system there my mouse never freezes. As you can well imagine this is driving me crazy and I can't continue to work like this. Moreover my bluetooth device setting is gone, so I have no way to use my keyboard which was working. Reproducible: Always
Forget this bug, it was google-hangout install on my system afaik. I did a fresh install of Kubunutu and problem gone.
