Two screens for working are connected via DVI and HDMI.
One HDMI output is connected to a PlayStation VR Headset. The Headset redir=
ects
all input to the TV but it is mostly turned off.

When turned off but connected to the HDMI output, frequent EDID read fails =
are
reported to syslog:

> [drm:log_to_debug_console [amdgpu]] *ERROR* No E=
DID read.

When un-plugging the PSVR Headset from HDMI the errors vanish. After the ED=
ID
read there is the HMD related messages like

> [    3.066968] [drm:log_to_debug_console [amdgpu=
]] *ERROR* No EDID read.

All connected Screens then reconnect: They turn black and the position of t=
he
screens (which is left and which is right screen) is sometimes also reset. =
This
is annoying during productive work.

My point is that I don't mind if there is no EDID from the PSVR HeadSet or =
any
of the connected devices. The headset is turned off and As I see it, it sho=
uld
only check for the EDID when I turn it on.

The only quick solution here is to unplug the Headset while on Linux.
