Stuck on black screen after update on Gnome

when you update you have to rebuild that because of the python update

Don't forget to recompile optimus-manager AUR after upgrading to python 3.9.0

Thinking more, there’s not an obvious way to repackage as a hook runs as root (so makepkg will refuse to run). However, it’s at least possible to flag packages which need a rebuild (or at the very least highlight files that are in the wrong place now).
