Some time ago, when I closed my laptop, Linux automatically hibernated,
now it does not. As my laptop becomes really warm and I don't want to
stress my display, I'm using this rarely, so I cannot tell, since when
hibernation doesn't work :-/
Kind regartds

These messages are related to Optimus system (Nvidia implementation of dGPU power management handling is not compliant with ACPI specs). So that’s not related to your hibernation issue.
Hm, I'm using the Nouveau driver - is this message hardware-related?
Regarding this one, I’d like a precision that might be useful: is this about hibernation or suspend?
Hm, I'm usually not distinguishing those. As System doesn't need much
time to wake-up, I'd assume it just suspends to RAM - but as computers
are getting more power, this is probably not really visible. How can I
detect, which mode it had to switch to?
Other than that, what DE do you use if applicable? What does handle lid close event? I had the issue that the lid close event wasn’t handled because KDE PM daemon isn’t inhibiting systemd one correctly, and once fixed it worked again.
Using XFCE. Don't know, what handles the lid close evenet - how can I
find that out?
Kind regards
Peter
