Without GreeterScreen= in tdmrc set to the correct screen, the login window
doesn't appear, only the un-asleep screen displays anything, which is nothing but
blue if incorrectly set. Correctly set, login is possible, upon which the other
two displays work as expected.

The HDMI-connected display is the only one not put to sleep for active TDM.
/etc/X11/xorg.conf does not exist, and /etc/X11/xorg.conf.d contains nothing
applicable to display configuration.
I also have for positioning displays:
# cat /etc/X11/xinit.d/po3set-kms60
xrandr --output DP-1 --primary --mode 2560x1440 --rate 60 --output HDMI-1 --above
DP-1 --mode 1920x1200 --rate 60 --output HDMI-2 --right-of HDMI-1 --mode 1680x1050
--rate 60

I only added rates to it today trying to determine what is going on. All was good
using it as it was in March, but this failure started about a month ago when
kernel 6.18.22 was freshly installed.
