Hmm, I upgraded mutter from eoan-proposed and gnome-shell from eoan- proposed plus those three commits (https://launchpad.net/~andersk/+archive/ubuntu/ppa, if you want to check my work), but it didn’t resolve the problem. Even after a reboot, gsd-xsettings doesn’t start and X11 applications don’t get themed.
