  • @vivek-patani, could you try the solution indicated in the answer Peter Uithoven linked to and let us know if that applies to your problem? Otherwise, this question would need more details to troubleshoot the actual issue, in which case a bug report would probably be a better place to carry on that process.

I have the same laptop the problem is with Nvidia driver.

you need to install "additional drivers"

sudo apt update 
sudo apt install ubuntu-drivers-common

Or you can open AppCenter and install "additional drivers" from there.

I'm not sure that the package is called exactly that but you can look it up for the exact name

after everything is installed open additional drivers app and select Nvidia 381 driver

that should fix your issues

  • So figure out / verify the right nvidea driver, you can use the NVIDIA Driver Downloads page: nvidia.com/Download/index.aspx Jan 15, 2018 at 13:45
  • ha? i've already figured it out

  • I was just trying to add more information, for people who might have slightly other hardware. And I remember how confusing those driver numbers where to me. (The "So" was a typo, should have been "To") Jan 16, 2018 at 9:19

I answered a similar question here. It could be a service is getting hung and can't shutdown properly. This fix adjusts the timeout for hung services.
