gnome-base/gnome-settings-daemon-50_beta breaks primary-clipboard middle-button paste

This seems like a design decision rather than a bug. If you, like me, like the ages-old copy and paste as select - mid button paste, this is the fix gsettings get org.gnome.desktop.interface gtk-enable-primary-paste returns false is the current default Change it with: gsettings set org.gnome.desktop.interface gtk-enable-primary-paste true
