What are the SELinux permissions after you have logged out?

Do you need that chcon command call when resuming sessions or when  
starting sessions.

Excuse my SELinux innocence at this point. I would like to add support  
for SELinux, but I need to understand better why we have to tweak the  
security context of .Xauthority for X2Go.

Thanks+Greets,
Mike
