Laptop: Lenovo Legion Y730 15' with Ubuntu 16.04 LTS (64-bit)


  • Processor: Intel® Core™ i7-8750H CPU @ 2.20GHz × 12
  • Graphics: Intel® HD Graphics (Coffeelake 3x8 GT2)
  • Graphics: nVidia GTx 1050ti

Please help - I am at my wit's end. I am new to Ubuntu so I am sure that there is something very simple that I am missing but I cannot seem to figure it out. I cannot seem to get my discrete nvidia GTX 1050ti graphics card to work in 16.04. I recently purchased a Lenovo Legion Y730 laptop that has both an intel graphics card and an nvidia card. No matter what I try, the driver does not seem to be loading/running the card.

I have followed all the instructions I found on this similar post: Cannot get NVIDIA graphics card to work on Ubuntu 18.04

To be specific, I have:

  1. Purged all nvdia
  2. Downloaded the ppa
  3. Installed and tried various drivers including the recommended version
  4. Blacklisted the nouveau drivers
  5. Rebooted
  6. Finally, ensured that secure boot is disabled.

I have tried almost every variation to these steps found in other troubleshooting posts. I have even recently tried a fresh-install to no avail.

I cannot connect to any HDMI monitors (which I desperately need), I cannot even open NVIDIA X Server Settings. When I click on the application, the icon blinks in the side bar then disappears. When I try opening it from the terminal, I get the following:

ERROR: Unable to load info from any available system

Below are some outputs that may be useful for troubleshooting:

Above it shows that the display for the nvidia card is "unclaimed" but I am not sure how to remedy this. The drivers seem to be downloaded, and when I check additional drivers, it shows that the nvidia driver is in use. Is there anything that I am missing, or any other threads that I have not been able to track down that shows how to solve this?

If any more information is required please let me know.
