I have upgraded my ubuntu from 10.11 to 11.04. The problem is, there is a horizontal mouse dead zone, I can not click in that area.
My laptop is Acer Aspire 5920G
But, when my friend installing ubuntu 11.04 in Vaio laptop, he gets the same problem with me, there is a mouse dead zone in the same area.
Anyone can help me to fix it?
I can not click on that zone (highlight in image)
