Same identical issue with Fedora 36 (Mate/Marco windows manager)

fakexrandr-manage

Does adding import gi; gi.require_version('Gtk', '3.0') to the top of the script, straight before the first other Import, suffice to fix this?

[BrutPitt]

Thanks for the fast reply.

Yes, It works for me.
Adding import gi; gi.require_version('Gtk', '3.0'), just after from __future__ import print_function, in fakexrandr-manage script

Thanks again.
