Ubuntu 16.04 black screen when shutdown / hibernate / restart

Asked by Thiru on 2017-04-20

From this stack overflow question: Sorry to repost but I would really file this under a significant bug as nothing is working.

Basically, I just clean installed Ubuntu 16, and I can't shut down the laptop. I

Now, when I press shutdown, it goes into a black screen with a terminal like "_" at the top left corner, and it's frozen. This seems different from the other stack overflow threads. I have to hard reset to shut it down.

Same goes if I close the lid, or press restart. `sudo shutdown` isnt working either.

Seen the below few threads, none of them really help.

https://askubuntu.com/questions/764568/ubuntu-16-04-hangs-on-shutdown-restart <-- Interested in the second solution but I cant seem to locate and install just that update hes talking about?



Tried nearly all the grub based and other solutions there, but nothing is working.

Core i7 7700HQ
Nvidia 1060GTX (Currently disabled - running on intel graphics)
Linux kernel: 4.8.0-46-generic

Would appreciate help, Thank you! :)


Tried https://askubuntu.com/questions/508029/ubuntu-14-04-stuck-on-shutdown as well but still nothing is working.

I noticed NVIDIA PERSISTANCE DAEMON kept failing to load. If i do

`sudo prime-select nvidia` to switch to nvidia driver, I am able to shutdown / reboot via GUI. Command line still does not work.

Using intel graphics do not work though. Is there a solution?

Can you help with this problem?
