xenodm presents dark screen since snapshot of May 14th

[Dannis 't Hart]

Hello,
Just mentioning: since the May 14th snapshot, I get no further than a dark 
("blank") screen after booting, at the point that xenodm is starting up.
I put back the /usr/X11R6 directory tree from May 13th snapshot, everything 
works as usual.
This is on my Lenovo Thinkpad T490s.
Something buggy must have happened between May 13th and 14th snapshots.
Kind regards,
Dannis.
