[Bug 1875306] Re: System starts again after shutdown

[Eric Dalongeville]

I added "acpi=force" to my grub boot, no success.

I then rolled back my graphics driver from Nvidia prioprietary 440 to
Nvidia proprietary 390, and the issue is gone.

I don't really understand how the graphics driver is involved in the
shutdown process, and if Nvidia is to blame here. I'll let more skilled
people decide what to do with this bug report.
