Hello, First off, thank you for all of the hard work. Second, I have a laptop HP 9410US that I had installed 4.0r5. I had everything working. The problem was in that when I wanted to install the current NVIDIA driver v177 X would not start. I understand that repositories can cause a potential conflict. The laptop has a 6150Go chipset. Any suggestions on what I can do to get this working? Cheers, Marek
