You didn't say if you have a router between your system and the cable or (A)DSL modem or not. Assuming you you're plugged directly into the modem, it appears that the DHCP server for Comcast didn't populate your /etc/hosts file with your system's name when it obtained an IP, or didn't give it a name that will reverse-resolve. So, X can't start since it has no idea what machine "my_computer_name" is. Go to a console (CTRL-ALT-F1 through -F5), log in as root and check the output of "hostname". That's what your machine thinks its host name is. If it's not set, or it contains "localhost", then Comcast didn't send you a host name. If you did get a host name, try: # host `hostname` and see if an IP is returned. If not, then Comcast didn't populate their DNS entry appropriately. If it did return an IP, make sure that IP is the same as shown in the "ifconfig" for your network card. If they match, then try # host IPaddress If you don't get a response, then Comcast didn't populate their reverse DNS (PTR) records. Of course, if you have a router, it's one hell of a lot easier to give your a machine a fixed IP address on the LAN side of the router, set up the /etc/hosts file to have that IP and your host's name in it and let the router do the work (that's what I do). Another alternative is to change your machine's name to "localhost.localdomain" and restart X (hit "ALT-F7", then "CTRL-ALT-BACKSPACE" to restart the X server). I hate futzing with DHCP. I sure wish the ISPs would implement the whole standard instead of "selected parts" of it and use a DHCP daemon that adhered to the standard instead of Winblows servers.
