Now and again I’ve been experiencing poor performance in GNOME. Looking for a solutionI have found this tip here . It really works at leat for me.
Edit your /etc/hosts file:
$ sudo gedit /etc/hostsYou should see something like that:
127.0.0.1 localhost
127.0.1.1 basetta-laptopNow write on the first line your hostname (my hostname is basetta-laptop).
127.0.0.1 localhost basetta-laptop
127.0.1.1 basetta-laptopNow Save.
Explanation why
This is a fix for the new system that was started back in edgy where the host name was split off to 127.0.1.1, the problem is that some applications still look for the host name @ 127.0.0.1, so to keep those applications happy and running smoothly you simple need to add the host name where those applications expect it to be.
