The newly released Ubuntu 11.04 (Natty Narwhal) features Unity shell interface which displays the current user name the top right of the panel (MeMenu) that adds a personalized feeling to desktop users.
However some users might not be comfortable to have their username appears on the computer screen, especially when they are working on a publicly accessible computer or when they do not want their username to appear on screenshots or screen-casts of their desktop.
So to remove the username, one only need to open a console, and run the following command:
gconftool -s /system/indicator/me/display –type int 0
Before
After
Alternatively, you can also choose to display your own fullname on MeMenu. You can do that by running the following command:
gconftool -s /system/indicator/me/display –type int 2
You return to the default setting of displaying your current username, by running:
gconftool -s /system/indicator/me/display –type int 1
