Does doing Crtl-Alt-F2 then Alt-F7 wake it up?

That sequence woke up the laptop display, bit not the external display.
Do I need to put data in the /etc/X11/xorg.conf.d 50-* files? I do not
know when they are read.

It's possible something there might help. I don't remember your hardware.
Running in Xterm or Konsole, what is output from

inxi -G -c0

(install inxi if necessary), and

grep onnect /var/log/Xorg.0.log

???

There could be other clues if you susepaste Xorg.0.log.

I installed inxi and executed the suggested commands. The output from my
42.3 system is below, where both monitors appear. But the laptop monitor
was blanked and came to life after I opened the lid, but some time
later. I don't know why the delay. The output is below:
xorg.conf.d>inxi -G -c0

When I ran this on my Leap 15 system HDIM-2 was shown connected. But
there was no pattern on display. I went to the KDE environment and
looked at system-setting->display and only one monitor was displayed.
When I returned to my FVWM environment, and ran the commands again,
HDIM-2 was shown disconnected.

I will look at the man page and see what inxi does.

Thanks, I can susepaste the Xorg.0.log when we think there is a
significant one.
Don

Have you tried with the nvidia proprietary drivers instead of nouveau?
