I had this same problem as described by #11. I found that changing the
display driver to proprietary nvidia driver helped. The nouveau driver
was the issue.

Unfortunately the new Ubuntu kernel did not fix the issue, it only
worked fine during some reboots. I now tried mainline v4.16.6 and
v4.17-rc3, both did not fix the issue neither.

The system was only recently installed, so there was no other version of
the kernel before on this system. However, last week I could get my
hands on this system again and update/upgrade installed a new kernel
which fixed the problem, I did not have the possibility yet to check
whether it now also
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.16
Adding reboot=bios, reboot=pci, reboot=cold, reboot=warm, reboot=efi,
acpi=force to the kernel parameters list did not help.
