/etc/hosts seems to be behaving all right. Here is my /etc/hosts file. 
(I do not know where the 127.0.1.1 entry came from, but I commented out 
anyway.) Note: I now have "desktop" as the hostname and I am trying to 
change it to "earth".

127.0.0.1 localhost desktop
#127.0.1.1 earth.home earth
192.168.1.2 desktop.home desktop
192.168.1.3 laptop.home laptop


# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Here is the result of localhost --fqdn (after successful boot retaining 
the name "desktop" by manually editing /etc/hostname):

   # hostname
   desktop

   # hostname --fqdn
   localhost

Here is the result after changing the name to "earth" with the hostname 
command:

   # hostname earth
   # hostname
   earth
   # cat /etc/hostname
   desktop

   # hostname --fqdn
   hostname: Unknown host

I still cannot work out how hostname is remembering a name ("earth") 
that it has not saved in /etc/hostname (which still contains "desktop"). 
hostname --fqdn is also confused and cannot find a host!
