It also locks up for me with user switching.
Also, when I log out the user from :1, it does something bad to session 
on :0 - monitor does not detect any output any more, but the session is 
still running (nothing is displayed, so it's not of much use).
No such phenomenon if I log out the user in session :0.

I'm sure anyone will be able to fix simple issues like that on his/her own.

As a side not, I was wondering if it's possible to set up multiseat 
using just one card (i.e. two seats with one ATI card which has VGA and 
DVI outputs)?
