Already tried this (installing Kernel 4.4), this (E: Unable to locate package nvidia-364)

  • Welcome to Ask Ubuntu! Did you by any chance try reseating/replacing the HDMI cable? Please edit your post to include the output of sudo lshw -C display which will tell us about both the video chipset and the driver in use. Thank you for helping us help you! – Elder Geek Feb 16 '17 at 21:30

    Many people have found this useful. There are a couple other answers there as well. Let us know if those don't resolve your issue and we will dig a bit deeper. Note: available packages are found here. I think 364 is a typo or obsolete... – Elder Geek Feb 16 '17 at 22:07
