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:
# ps ax | grep kde

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?

Hi Mike,
I have a TDE 14.0.7 with two screens on Debian Wheezy and Debian Stretch.
However, both configurations are that one TDE session is used over both
screens => $DISPLAY is simply ":0" and one kdesktop is running. And
everything works fine.
As you can see from your list of processes, for R14.0.6 kdesktop is also
run incorrectly and kdesktop_lock is even more incorrectly. There should
always be one kdesktop + kdesktop_lock pair per TDE session. The question
here is whether these multiple kdesktop processes really work, or if there
was no crash (and therefore no flicker) just because one of them is stuck
and doesn't really work?
Here are the questions for which we need to find the answer:
1. Why is more kdesktop running?
Is there one TDE session or more?
2. Why does kdesktop crash?
Note: In any case, thank you for adding information about the situation -
at the beginning I did not know what to imagine under the flickering and
therefore I thought it was xserver crashes.
Cheers
