[Bug 1576909] Re: Suspend not working on Ubuntu 16.04
saguti, the next step is to fully commit bisect from kernel 3.13 to 4.4
in order to identify the last good kernel commit, followed immediately
by the first bad one. This will allow for a more expedited analysis of
the root cause of your issue. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit
bisecting.
Also, the kernel release names are irrelevant for the purposes of
bisecting.
After the offending commit (not kernel version) has been identified,
then please mark this report Status Confirmed.
Thank you for your understanding.

Title:
Suspend not working on Ubuntu 16.04
Status in linux package in Ubuntu:
Incomplete
Bug description:
I am running Ubuntu 16.04 on an Acer Aspire V3-472G with Nvidia
Geforce 840M graphic cards, proprietary driver.
None of the options for suspend are working. The process of suspend
works fine but when the computer is waken, screen stays black and
computer becomes unresponsive.
Installation of packets such as uswsusp create a bigger problem as the
computer freezes during boot process.
