1.查看系统日志
less /var/logs/message
May 12 21:54:41 localhost python: SELinux is preventing /usr/libexec/ibus-x11 from read access on the file /usr/share/themes/Ant/gtk-3.20/gtk.css.#012#012***** Plugin catchall

看报错确实是语言环境问题
2.把语言环境调整过来
Applications----->System Tools----->Setting--->Region &Language
确保 "Language" 和"Formats"是对应的，比如，Language是English的话，Formats也一定要是English才行，不管你是美式英语还是英式英语
3.设置好后重启电脑就恢复正常
