I had installed Kubuntu 16.04 from daily build about two weeks ago, using only Intel VGA iGPU. Then day 2016-01-05 I installed an NVIDIA GT 430 card and proprietary nvidia drivers "nvidia-352-updates" from the repositories (using package manager). The nvidia driver and the system worked well. The day 2016-01-09 while I was using the system, the screen started to do some strange things and the system crashed/locked. By forcing a reboot I never was able to start Kubunu with nvidia proprietary drivers. The screen goes black with prompt flashing in the upper left corner, and I can not even enter a TTY teminal using nvidia driver. So what I do is to enter recovery mode and from command line I uninstall nvidia driver. Restarting with "nouveau" the system also does not start the X display, I get black screen (without the prompt flashing), but with "nouveau" I can enter to a TTY terminal and with "startx" I can enter to the system in graphic mode . Now with "nouveau" and starting with "startx" everything seems to work fine, but I always get the black screen when startup the system, so I always should start graphics mode with "startx". In short, from the day 2016-01-09 using "nvidia" proprietary driver I can never start Kubuntu in graphic mode and I can not even enter to a TTY teminal. With "nouveau" I also get a black screen when start the system, but at least I can enter a TTY and start graphical mode with "startx". I am reporting for "nvidia-352-updates", but the problem still occurs with nvidia 304, 340, 361 from PPA. I also Try Kernel 4.3.0-2, 4.3.0-5, 4.4.0 mainline.
