OK, for comparison purposes I'm back to 14.0.5 and Stretch. (Something of
a struggle as Tim's server became inaccessible again during the downgrade.)
Dual display with first for Trinity and second was intended to be non-TDE as
before but TDE won't cooperate on that. However 14.0.5 works without flashing
or crashing. The unlock screen dialog pops up two or three or four times
after login but things eventually settle down.
Instead of the two lock files in 14.0.7 PSB there is a single lock file
in 14.0.5: /tmp/tde-mgb/kdesktop_lock_lockfile
However TDE 14.0.5 is running a second desktop on the second display.
Before upgrading to 14.0.7 and rolling back to 14.0.5 the systray randr
would allow me to specify which display was primary and which display(s)
TDE could or could not use. But now systray randr only shows one screen
and doesn't enable those options, despite TDE actually using two displays.
xrandr gives different results in each screen which don't list the other
screen. And I can't get kicker to appear in the second display although
it says that two instances are running and won't start another.
Behind the scenes, some weirdness is going on:

Has anyone had success with multiple displays in 14.0.7? Preferably with
TDE on one display and the second as an X display unused by TDE?
