How can I get /etc/X11/wmsession.d/45TDE in Mageia 7b2 (urpmi upgraded from Mageia 6) to run my xrandr script as it starts? other distros call it from various places, but I can't find a place that works in Mageia 7. :~(

TDM isn't working either, so I'm starting TDE with

startx /opt/trinity/bin/starttde

instead. Do I need something in /etc/alternatives to get TDM to work? If so, what? If not, then what?

I'm only trying to follow up on a bug: https://bugs.mageia.org/show_bug.cgi?id=10457
