I have installed ubuntu 12.04,without nvidia driver I can use my Laptop screen and a second screen over the HDMI port of my laptop.
For some reason when I install the nVidia driver 331.20 the second screen which is using the HDMI port is getting a mirrorscreen of my Laptop. The nVidia driver also doesn't recognize the second screen. But when I enter the ubuntu display setting it show both screen overlapping each other. When I try to put on screen beside the other one and click on apply, both screens turn black and I get logged out but both screens are still mirroring.
Anyone got a pointer for me how I could fix this? If any logs needed to better trace my Issue please tell me as I'm new to unix/linux.
