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.

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

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 Cheers -- Slávek
