fedora 28 usb live 可以boot起。但gcin用不到，conflict with ibus。如dnf erase ibus後，整過fedora 28 hang機 　 ！ 都是用回fedora 27 好了。

我是根據老刀兄的方法安裝的： https://fedora-tw.org/t/fedora-21-workstation-gcin-fedora-22-23/29 

#dnf install gcin*

結果：成功。gcin 版本是gcin.i686 2.8.5-4.fc28

#reboot

$im-chooser

結果：command not found, but ask to install. 

install im-chooser-1.7.1-4.fc28.i386 成功

but popup screen : No INput Method

                            Use iBus (recommended)

#gcin

結果：IMOpenIM 'ibus' failed. Maybe another XIM server is running

$gsettings set org.gnome.settings-daemon.plugins.keyboard active false

結果：No such schema "org.gnome.settings-daemon.plugins.keyboard"

--------------------------------

我dnf erase ibus 之後boot 不起fedora 28。要用usb live重裝。 

Just find a bug report: keyboard plugin cannot be disabled so we cannot use any other input method than ibus
