Well, I wouldn't run a command if I wasn't able to figure out at least the basics of what it was going to do. But from other replies I thought I wouldn't need anything too fancy to accomplish my goals anyway. And, based on other replies I edited 'hosts', 'hostname' and 'mailname'. Then rebooted. The DM (LightDM) still will not start. I changed to another virtual terminal (by that I mean I pressed <Ctrl><Alt><F1>), logged in a root and ran 'startx'. That worked OK. To look for references to my old and new hostnames I ran the following command: "grep -rH "HOSTNAME" in /etc and substituted both old and new names for HOSTNAME. The 3 files I edited earlier still had the new name. The only file with the old name is exim4/update-exim4.conf.conf, and that doesn't look like it would cause the problem. There are over 20 files with the word 'localhost' in them, but not with '-01', so far my guess is that it is just used to reference the host machine even when it is not the actual hostname. So, maybe this is something specific to LightDM. I did check the files in /etc/lightdm but there were no reference to "host', local or otherwise. I started searching through my log files and thought this might help. These are entries from the most recent boot up, which is when LightDM would not load: Auth.log - Dec 21 16:36:38 (none) lightdm: pam_unix(lightdm-greeter:session): session opened for user lightdm by (uid=0) Dec 21 16:36:38 (none) lightdm: pam_unix(lightdm-greeter:session): session closed for user lightdm Dec 21 16:37:13 (none) login[3563]: pam_unix(login:auth): check pass; user unknown Dec 21 16:37:13 (none) login[3563]: pam_unix(login:auth): authentication failure; logname=LOGIN uid=0 euid=0 tty=/dev/tty1 ruser= rhost= Dec 21 16:37:15 (none) login[3563]: FAILED LOGIN (1) on '/dev/tty1' FOR 'UNKNOWN', Authentication failure Syslog - Dec 21 16:36:38 (none) avahi-daemon[2285]: Server startup complete. Host name is none.local. Local service cookie is 3853520009. Then, still in syslog, I noticed two consecutive lines: Dec 21 16:36:01 localhost-01 rsyslogd: [origin software="rsyslogd" swVersion="7.4.4" x-pid="1899" x-info="http://www.rsyslog.com";] exiting on signal 15. Dec 21 16:36:36 (none) rsyslogd: [origin software="rsyslogd" swVersion="7.4.4" x-pid="1922" x-info="http://www.rsyslog.com";] start Based on the time stamp these happened during the most recent boot. All the previous lines have 'localhost-01' then all the subsequent lines have '(none)'. One other thing - I rebooted again and tried the command 'service lightdm restart'. It worked, sort of. I was able to log in, but my desktop didn't start right. There were no panels, and when I tried to run a Mate configuration app they wouldn't run. I switched back to the virtual terminal I ran 'service lightdm restart' from, and there were no error messages. Darn :-(. Other suggestions?
