I don't know if the following is related but I made settings according to: https://bugs.launchpad.net/gnome-shell/+bug/1968040

I added this option:

MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0

to

/etc/environment

Now both screens don't turn off - the internal screen and the external screen. The screens just get blank.
