gtk3-engines-unico was recently removed from stretch because it apparently doesn't do anything any more. See https://bugs.debian.org/822976
>From its description, gtk3-engines-xfce sounds like something different; it claims to allow regular GTK3 themes to be used by Xfce. But maybe it's just as obsolete as Unico since it has no reverse dependencies and I'm able to use Breeze fine on Xfce without it. It seems to me like Breeze is a GTK theme not a GTK3 engine. For one thing, it supports GTK2 too! Here are the other GTK theme binary packages I am aware of in Debian: - albatross-gtk-theme - arc-theme - blackbird-gtk-theme - bluebird-gtk-theme - clearlooks-phenix-theme (removed from stretch because of GTK 3.20) - greybird-gtk-theme - gnome-themes-standard (GTK2 only now since GTK3 itself bundles the GTK3 version of Adwaita) - mate-themes - murrine-themes (GTK2 only) - numix-gtk-theme (well it's an ITP, but it will be in Debian soon) Ubuntu also has - light-themes - ubuntu-mate-themes - yuyo-gtk-theme and several old GTK2 themes Therefore, I propose that the binary package be renamed to breeze-gtk-theme. Thanks, Jeremy Bicha
