gksudo is also useful if you are backgrounding the task using &.

'sudo gedit /etc/X11/xorg.conf &' would result in sudo asking for a 
password in the background, but no way for you to enter said password, 
as you have already been given a new command prompt.  I believe that 
this is the situation gksudo is made for, as 'gksudo gedit 
/etc/X11/xorg.conf &' would pop up the gui password prompt at the same 
time as giving you your new command prompt.
