I have a PC with 2560x1440 on DisplayPort, and 1920x1080 on HDMI. The greeter shows up on the small HDMI screen. Is there something in tdmrc or friends that can move it to the DP screen, and preferably, start off TDE sessions by default with the larger/DP screen as the primary? I know how to use xrandr to make the DP primary, but it's not working for the login greeter. It tried it in /etc/trinity/tdm/Xsetup, but it's apparently ignored or otherwise ineffective there.

Hi Felix, I think it depends on which display is set as your primary display. I do not remember exactly but I think you can configure this as root for the login screen. For example the Greeter should be configured to use mirrored displays (default) and the user should be extended display. In this case you get login screen on both displays and after this the user configuration is loaded with extended setup.

I don't find the strings mirror or extended in tdmrc.dpkg-dist or the abbreviated tdmrc. I know what you're describing, but I don't see any such settings in TCC. In Monitor & Display, everything is grayed out. In Login Manager settings, the only things I see having to do with display selection are an Identify Screens button, and a select list for how and where backgrounds appear.
BTW, I'm trying to get this to happen using Intel IGPs on multiple PCs on both openSUSE and/or Debian first, then others, once (if?) successful.

It is under Administration monitor and display (or similar)
I used and use only Intel IGP. On some of them I had to write custom xorg.conf and for the user I had to enable script to extend the screen.
DSPL=`xrandr | egrep "[[:space:]]connected[[:space:]]" | grep -v eDP | cut -d ' ' -f1`
if [[ "x"$DSPL != "x" ]] then xrandr --output eDP --auto xrandr --output $DSPL --mode 1920x1080 --right-of eDP --auto exit 0 fi
So it also depends on the IGP

I've looked now what is in the setup of the notebook.
1. xorg.conf is setup to mirror on both displays (this is how you get login on each of them) 2. the user copnfiguration (xrandr or tderandrtray) takes care to extend after login.
I am not sure right now if TDE is "memorizing" the selected configuration (per monitor ID or so like Windows does) Obviously here on the notebooks it was done with the script.

Screens order is determined by xserver. If it is a desktop computer instead of an empty xorg.conf and keep the configuration on the autodetection result, you can force the screen settings by writing the desired configuration parts to xorg.conf.
In any case, in the tdmrc is also possible to use setting GreeterScreen=<screen> to enter location other than the primary screen:
# The screen the greeter should be displayed on in multi-headed and Xinerama # setups. The numbering starts with 0. For Xinerama, it corresponds to the # listing order in the active ServerLayout section of XF86Config; -1 means # to use the upper-left screen, -2 means to use the upper-right screen. # Default is 0
