[ubuntu] Mouse stuck between two screen

view story

http://ubuntuforums.org – Hello, When I add an extra screen and try to move the mouse between the two screens, the mouse cursor is blocked on the edge of the monitor and I have to move the mouse faster to reach the second monitor. When I googled for this problem, the solution seemed to be the deactivation of the sticky edge option for monitors (Diplays settinngs). But this is not working for me. The solution I found is to disable the auto-hide of the Unity Launcher (Appearance/behavior). But now, I see the Unity launcher all the time and it takes to much place. Does anybody have a solution to remove the mouse &quot (Hardware)
