I have the same problem as sohel, where the original issue is fixed but my external monitor is not detected by Nvidia Prime. I created a question here:
http://askubuntu.com/questions/550750/nvidia-prime-does-not-detect- external-vga-monitor-after-updating-ubuntu-drivers but there are no answers. I have held `ubuntu-drivers-common` at version 0.2.91.5, which allows me to use the external monitor, but it causes other problems. Before this issue occurred, my setup was working fine.
