FWIW, GParted doesn't work on Wayland right now. And on Fedora 25 Live
media Wayland is the default with auto login. You'd have to give the
liveuser user a password and turn off auto login, log out, then at login
switch to GNOME on XOrg using the gear icon.
Or 'dnf install blivet-gui' and use it instead.
