Investigating a bit further, I can confirm that the lid.sh script works
fine once brightness is woking and doesn't even get called when it's
not. In other words, the script works perfectly, the event is not being
generated. Both brightness and lid events stop working at the same time,
I still can't figure out why...

It may be a red herring, but it tends to work for longer when the
machine is colder (after a long rest) and shorter when it's hot (on
gnome login it's already dead). Could be some mess up with the thermal
control?
