Bug Description
Since a few weeks, my displays won't wake up from display powersave. The machine stays responsive via SSH.
This first occurred on Ubuntu 18.04, and keeps happening on 18.10 (which I had updated to in the hopes of fixing the issue that way).
The only escape I've found from this state is via magic SysRq.
It can be triggered reliably by waiting for the screensaver to kick in (e.g. overnight).

It appears the 'amdgpu' kernel driver is crashing. That is part of the kernel package 'linux'.
