I just got the solus budgie 20170101 installed. And I installed the ibus using
sudo eopkg install ibus-libpinyin
and set it as the default input method in gnome settings. But when I start to type, the window for charactor choices just does not show up. Maybe ibus is missing some gtk dependencies?
(Also it could be really nice if you guys add fcitx as an alternative. It's much more powerful than ibus.)
