Have a look at 

apt-cache show sux 

Seriously :)

So

sudo aptitude install sux

peter at prospero:~ $ sux alterego xterm
Password:

< alterego's password>

[ usual complaints about MIT magic cookies and authorisation, but xterm
pops up anyway, with the user as alterego ]

If I switch user to "alterego" with "su alterego" on the command line, and
then try to run xterm, I get the expected

alterego at prospero:/home/peter$ xterm
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

xterm Xt error: Can't open display: :0.0

"su" means "switch user" and requires the password of the user to which
you are switching - "sux" is the same but fixes the X authority issue.

Google  "MIT magic cookies" if you want to be thoroughly confused ;-)
