Indeed, ubiquity doesn't bother with checking the DHCP host name. Perhaps it should -- that would be a bug in ubiquity. This is possibly why you can't replicate the issue on virtual machines, in this case are you using the alternate installer?
Regardless, it's not really supported to remove /etc/hostname. The file should instead be modified if the hostname for the system changes, along with /etc/hosts (since it contains a "pointer" to 127.0.1.1 for that name). At the same time, if lightdm fails to find the hostname (which is "normal" if it's just looking for it in /etc/hostname), it's behaving correctly in showing "localhost". What *is* broken is that the desktop doesn't continue to load cleanly and instead falls back to the greeter. There needs to be some more investigation at the lightdm level for this; for the reasons listed by Sebastien. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1007221 Title: Removing /etc/hostname results in failed first login attempt To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1007221/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
