Thanks for taking the time to report this issue and make Ubuntu better.
To confirm, did you restart your machine after changing /etc/hostname
and /etc/hosts? Generally speaking changing the hostname without a
restart can cause the issues you're describing, because the previous
hostname is cached in the running applications (such as the graphical
display system).
