Maybe it is a solution.
I'm installed Ubuntu 16.04 and after that I updated system packages using apt-get, also I installed nvidia-361 right after packages updated. Result is black screen after restart. I deleted nvidia driver, and also I found two kernels installed in my system, I removed old kernel and reinstalled nvidia drivers and reboot. It works now!
