Actually, it's not just laptop's screen which goes blank,
this same happens to external monitor. It seems random as to
which/when monitor goes blank.
I think it is new in 37th Mesa and its AMD drivers.
F37 dropped vaapi support from mesa because of patent issues. I don't
know if that is your issue, but there are freeworld packages on
rpmfusion that restore the functionality. But, they require a
dnf swap to do so.
dnf swap mesa-va-drivers mesa-va-drivers-freeworld
dnf swap mesa-vdpau-drivers mesa-vdpau-drivers-freeworld
If you just upgraded, then you probably don't have an older kernel to
try, but you could try a newer kernel by updating. Also, you could get
an older kernel at
https://koji.fedoraproject.org/koji/packageinfo?packageID=8
by downloading the kernel rpms you have installed and install it with
dnf -C install [kernel rpms you downloaded]
in the directory where the rpms are.
