I have install Xubuntu 12.04 LTS. Everything works fine except that when I watch a movie especailly fast action scene. It has a hroizontal line running across the screen. I have install the nVidia driver as recommended and try severall setting but fail. When I switch to Kubuntu the problem gone.
So I was wondering whether there is a difference between the 2 distro and how to solve the problem? I like Xubuntu because of its light weight. Thanks in advance.
