Changing System name
Solution 1
You have to change the computers hostname as well.
Edit the hostname file and replace the name
gksudo gedit /etc/hostname
also change the name in hosts
gksudo gedit /etc/hosts
Leave the other stuff there untouched.
For the username, it would be cleaner if you deleted the old user and created your new one.
Solution 2
You'll have to edit /etc/hostname
and /etc/hosts
, and replace the old hostname with the new.
PS: On the second thought, I'd probably just reinstall to get a clean system.
Solution 3
Open a terminal window.
Input the following command and hit Enter: gksudo gedit /etc/hostname
When prompted, enter the administrator password and click the OK button.
The hostname file will open, displaying the current computer name. Replace the current computer name with the desired new name.
Click Save.
Close all open windows and restart your system.

Hussain Nagri over 1 year
I am given an old Ubuntu working system and the previous user had everything on his name so started turning it to my name as typing his name everywhere was bugging me. I tried:
$ usermod -l hussain darhamid
This turned the
darhamid@darhamid:$
intohussain@darhamid:$
But I want
hussain@darhamid
:$ also changed tohussain@hussain
. What should I do?I am using ubuntu 12.04

fabricator4 over 11 yearsAgreed: it's best to make a new user, however it should be pointed out that the new user must be an admin user and must have sudo rights, otherwise the system can never be updated or have new software installed. Perhaps it would be wise to leave the old admin user there as a recovery option.

phoibos over 11 yearsYou're right, if you don't know how to do this, better leave it as it is ;D

Aquarius Power about 11 yearsafter reboot, at network connections, while editing wireless hotspot, the old name remained.. my guess is we should grep the whole system for the old name to see if it was left untouched somewhere else :(. Here I have these /etc files
/etc/cups/printers.conf.O
,/etc/cups/printers.conf
and/etc/NetworkManager/system-connections/Hotspot
that still contained the old name :(, my guess is not other places for it to be "hiding" :> -
Aquarius Power about 11 yearsFor the hotspot file you can use the network connections configuration, thats surely safe. The printers configuration, at properties, will handle the cups files.
