Found a partial solution that seems to address the instant wak=
e up under
Wayland.

It seems that by default, the AOS2770SHE starts polling once display
disconnects on one of its inputs. This seems to cause the actual system to =
wake
up. However, this was not an issue before and used to function with no prob=
lems
previously. It seems that something in amgdpu DC code changed that is picki=
ng
up these polling requests.

To get the monitors to sleep properly, I did the following:

Set "Input Select":  Auto -> HDMI1
Set "DDC/CI": Yes -> No

Now the display sleeps as expected and wakes up with no issues. Still would
like to know what changed to cause this to appear. I usually need to have t=
he
inputs set to Auto as I have a docking station plugged into the monitors for
the work laptop.

Also amdgpu.dc=3D0 hands the system and it's only becomes accessable throug=
h ssh.
However no errors are present in any logs. But I'll file a different bug on=
ce I
nail it down to a specific component.
