so... my testing missed something stupid
the display that i assumed to be behaving correctly may be were the actual
issue is - after the first "dpms off" both turn off as expected but the one
that i assumed to be turning on correctly ( due to my lack of Patience...)
seems to turn on without any input from my part almost immediately after
turning off - the second (soon after) time all works correctly
... and reading my original bug report it almost sound like thats what i said
:/

When testing dpms, try something like this:
sleep 5; xset dpms force off
so that you avoid any late input events that might come in after turning that
displays off that might make then come back. Please also attach your xorg log
and dmesg output.

re-tested via ssh to to eliminate delayed events (and i now have 3 screens...)
xset dpms force off:
all displays turn off
then almost immediately DVI-0 and HDMI-0 turn back on but DisplayPort-1 stays
off
xset q states "monitor is off"
then i press shift( cause an event):
xset q states "monitor is on"
DVI-0 and HDMI-0 stay on and DisplayPort-1 stays off
then "xset dpms force off" again
all 3 displays turn off
xset q states "monitor is off"
then i press shift( cause an event):
all 3 displays turn on
xset q states "monitor is on"
this is a repeatable loop

Do the DVI/HDMI monitors have an option to probe all inputs at some regular
interval? If so, can you turn that off and see if it helps?

i checked the settings and found nothing, so i decided to switch the displays
around to see what happens...
original layout (1):
dvi -> 1
hdmi -> 2
dp -> 3
layout 2:
dvi -> 2
hdmi -> 1
dp -> 3
ran xset dpms force off via ssh
all 3 turned back on but "3" was distinctly after 1,2
(under setup 1 they all turn back on at about the same time the second time
round)
xset -q says displays off
same result every time
layout 3:
dvi -> 3
hdmi -> 2
dp -> 1
same result as layout 1 but it starts at a different point in the loop -
xrandr says display on but display 3 is off immediately after starting X
it may have something to do with a race condition relating to the speeds the
dislays "start" ( i probably have no idea what i am talking about...) as when
setting up xorg.conf if i used "right-of" it complained about missing modes or
something - it only worked as i expected it to when "left-of"'d from display 3
will investigate further in the next few days

i updated mesa, ddx, kernel - drm-fixes
the issue is not reproducible in the same way
i am yet to find a consistent way to do it and it happens very rarely under
normal use
i do find this error in dmesg odd as there is no "display port" plug in use:
[drm:radeon_dp_get_link_status] *ERROR* displayport link status failed
[drm:radeon_dp_link_train_cr] *ERROR* clock recovery failed
i get that error in dmesg atleast one for every time it happens
unless anyone else experiences this ( or you want me to look into it further )
consider this "resolved enough" :)
thanks, aaron m
